Notes on markets, sentiment, and building an AI research platform in public.
How to use ChatGPT for stock analysis with live market data: add the SentiSense connector from the Plugins page, sign in with a free account, and ask about sentiment, analyst targets, insider and 13F filings, options and earnings. With the connector's own October 28, 2026 output and a reusable prompt.
By SentiSense TeamWhat commercial use means on a stock market data API, the difference between showing data to your users and redistributing it, what the major vendors' terms allow as read on October 28, 2026, how a self-serve data license covers an app, a newsletter or an AI research product, and where the line sits on the ordinary Pro plan.
By SentiSense TeamThe parts of an AI agent, explained for people who use ChatGPT or Claude every day: the model, instructions, context, tools, connectors (MCP), skills, memory and the loop, each with a plain definition, a real-life example and a small diagram, with stock research as the running example. Plus why the model you pick and where the agent runs change what it can do.
By SentiSense TeamAnthropic filed its IPO prospectus (Form S-1) on October 26, 2026, to list on Nasdaq as ANT. Of its $80.7 billion first-half net loss, $72.4 billion is a fair-value change on convertible notes; it lists hundreds of billions of dollars of multiyear compute commitments; and one founder share carries 50.1% of the vote.
By SentiSense TeamBig tech earnings this week: Microsoft and Alphabet report after the close on Wednesday, October 28, 2026, and Amazon after the close on Thursday, October 29. Dates and call times, consensus EPS and revenue, each company's own guide, eight quarters of Azure, Google Cloud and AWS growth, capex and its stated outlook, and the implied move modeled from SentiSense options data for the October 23 session beside the average move over the last eight reports.
By SentiSense TeamWho owns a stock? See institutional ownership from SEC 13F filings: the largest holders, their share of the company, notable funds and quarterly buying and selling, in the app, the API and the MCP connector.
By SentiSense TeamA 13F filing reports an institutional manager's quarter-end holdings. Learn the $100 million test, the November 16, 2026 deadline and what the report leaves out.
By SentiSense TeamMeta is not doing a stock split. On October 21, 2026 it announced a one-for-one stock dividend of a new non-voting Class C share, effective January 19, 2027, and said it expects Class A to trade as if split two-for-one. What Class C is, who keeps the votes, when the shares arrive, what Meta says about taxes, why Meta says it is doing it, and why the $3.83 EPS headline is not what it looks like, cited to Meta's SEC filings.
By SentiSense TeamThe implied move for earnings is the size of the one-session swing, either way, that option prices build in for a report. The straddle formula, the IV approximation, and a dated table for October 21 to 23, 2026: Meta, Tesla, IBM, Texas Instruments and 18 more, each with the implied move from SentiSense options data, the average move over its last eight reports, and how often the stock beat the implied.
By SentiSense TeamA price target is one analyst's estimate of where a stock could trade in about 12 months. How targets are built, why Buy ratings dominate, how often targets are met (one study: 38% at 12 months), and how to read the 59 targets on Nvidia as of October 18, 2026.
By SentiSense TeamA yfinance alternative for AI agents: an official stock market API with published limits, SDKs and MCP, and a key your coding agent gets with no signup. What yfinance is, when it is still the right tool, and what SentiSense adds: sentiment, insider, congressional, 13F, options and earnings data, with every yfinance claim read from its README, GitHub tracker and Yahoo's terms on October 17, 2026.
By SentiSense TeamHow to use Claude for earnings season with the SentiSense connector: who reports this week, why a stock fell after its report, which number it beat on, how its options are positioned, and what last week's bank earnings say about the next. With the connector's own output from October 16, 2026.
By SentiSense TeamSeven end-of-day options readings are now screener fields, in the same plan as the SentiSense Score and analyst consensus, and a new endpoint returns the options session in 15-minute cycles so a signal can be tested before it is used.
By SentiSense TeamMarket data APIs compared for AI agents, LLMs and trading bots: which vendors run a hosted MCP server and how it signs in, who publishes llms.txt, a skill file or an OpenAPI spec, rate limits an agent loop can live with, coverage beyond prices, and pricing read on each vendor's page on October 13, 2026.
By SentiSense TeamGive Cursor a live market data feed in two minutes: add the SentiSense MCP server by URL or install the skills with one command, and the agent screens stocks, reads sentiment and writes the script that reruns the research every morning.
By SentiSense TeamUnusual Whales API alternatives for options flow and unusual options activity, every price read on the vendor's own page on October 13, 2026, plus OPRA licensing in plain English: professional and nonprofessional fees, display versus non-display, redistribution, and what delayed data changes.
By SentiSense TeamOne sentence to Claude and the SentiSense connector builds a dashboard that tracks your holdings with the research context around them: the SentiSense Rating, analyst targets, insider and congressional trades, 13F holders and the stories moving each stock. How we built one for MCD and TTWO on October 11, 2026, and what it cannot chart yet.
By SentiSense TeamThree checks to run with a Grok Bot that already has market data: a morning read on analyst moves, sentiment and the stories behind them; an after-earnings read that separates the print from the outlook; and a filings read on insider and 13F activity. Real answers from October 10, 2026.
By SentiSense TeamSentiSense is listed in Claude's connector directory. Connect it with a free SentiSense account and Claude answers with stock sentiment, the SentiSense Rating, news, analyst ratings, 13F flows, options positioning, earnings and reported financials, with no API key to paste.
By SentiSense TeamPython earnings calendar and earnings data examples: five scripts that list the week's reports, rank them by importance, read the market-wide beat rate, measure one stock's reaction to past reports and pull last quarter's report. One pip install, one key, each runs as written.
By SentiSense TeamSeven earnings calendar APIs compared on price, free tier, forward window and MCP access: Benzinga on Massive, Financial Modeling Prep, Alpha Vantage, Finnhub, EODHD, API Ninjas and SentiSense.
By SentiSense TeamWhich hedge funds beat the S&P 500 in 2025 and who leads 2026 so far: Bridgewater, Citadel, Millennium, Pershing Square and 20 more, every number cited to its source.
By SentiSense TeamThe Options Radar now runs during the session: a 15-minute delayed board of unusual contracts through the day, and the largest prints after the close.
By SentiSense TeamRobinhood Agent Apps cost $5 to $30 a month each with a one-month free trial, from eleven providers. Robinhood Agents trade from a dedicated agentic account with trade approval on by default. What each does, how the trading MCP fits, and the two settings to check before an agent trades.
By SentiSense TeamSix analyst ratings APIs compared on free tiers, price targets and verified pricing: Finnhub gives recommendation trends free but puts price targets behind a $3,500 a month plan, Alpha Vantage and EODHD return a consensus snapshot, Benzinga licenses by quote, TipRanks sells analyst track records, and SentiSense returns the full target band on a free key. MarketBeat and Zacks have no API.
By SentiSense TeamTwo SentiSense Actors are live on the Apify Store: a daily stock sentiment score per ticker, and a one-row research report with sentiment, insider and congressional trades and analyst consensus. Pay per ticker, no subscription, callable from the Apify console, API, schedules and MCP server.
By SentiSense TeamA SentiSense Data License lets your product show our market data to its own users, store it and use it commercially, month to month from $135. Pro Max raises the API rate to 1,500 requests a minute. Both are self-serve on the pricing page.
By SentiSense TeamAI stock analysis by investment committee: five investor personas each build a case from the same sourced evidence ledger, challenge each other, and a neutral chair writes the bottom line with the dissents on record. A worked example on META, run on live data.
By SentiSense TeamA fear and greed index API with a documented schema. SentiSense Market Mood returns a 0-100 fear-to-greed score for the US stock market, its phase, six signal components, sector scores and trading-day history. One free key, then curl, Python, Node, a CLI, an MCP tool or an agent skill.
By SentiSense TeamFive working Python examples for stock sentiment data: one stock today and over 30 days, whether a mention spike is good or bad news, the most bullish names in a watchlist, market-wide breadth, and sentiment lined up against price. One pip install, one free key, each script runs as written.
By SentiSense TeamFour ways to connect market data to an AI agent: a hosted MCP connector for Claude, ChatGPT, Codex and Grok, the Python and Node SDKs as tools in your own agent loop, a CLI for shell-capable agents, and installable skills. Which fits which runtime, with a runnable example.
By SentiSense TeamOnly five stock data APIs return a filtered ticker list in one call: EODHD, Intrinio, Benzinga, Alpaca and SentiSense. Which run free, plus a Python example.
By SentiSense TeamFive Python scripts for congressional stock trades, each runs as written: this week's disclosures, what Congress is buying, one stock's filings, filing lag by chamber, one member's history. pip install, one free key; two scripts need PRO for full counts.
By SentiSense TeamOpenInsider is a free Form 4 screener with no public API. Here is what builders use instead: SEC EDGAR if you want to write the parser, or a documented insider trades API with a 10b5-1 plan flag, cluster buys, and a working call.
By SentiSense TeamEvery covered stock now carries a daily SentiSense Rating, a letter from A to F built from a score you can check by hand: a rank across seven families of public signals, minus a published points table of risk conditions. It ships in Beta: the numbers are live for everyone, the response shape is stable, and the method will keep being tuned in the open, with every change versioned.
By SentiSense TeamGive Meta's Muse agent live stock market data in about five minutes: one free API key, one pasted prompt, and Muse builds a custom connector that can quote a stock, read its sentiment, check who is buying and see who reports this week.
By SentiSense TeamHow to give Grok, ChatGPT or Claude live market data without writing code, then eleven MCP servers compared on what they expose, how fresh it is, what the free plan really allows, and whether they run on the vendor's servers or on your computer.
By SentiSense TeamThe insider trading trackers people actually use in 2026, compared on plan-trade flags, cluster detection, alerts and APIs, with this month's GameStop cluster buy as the worked example.
By SentiSense TeamGive Codex a live market data feed in about two minutes: one free API key and one command, and GPT 6 Astra can screen stocks, read sentiment, check who covers a name and see who bought after earnings, instead of guessing from training data.
By SentiSense TeamEvery name in market news resolves to one typed node in the SentiSense ontology: a company, a person, a product, an organization or a topic. Here is why that matters for sentiment, and how to query the graph with three free calls.
By SentiSense TeamNeither wins outright. After two weeks running Claude Code and OpenAI Codex on the same product, Claude Code is better at building, Codex is better at reviewing, and the pairing beats either alone.
By SentiSense TeamQuiver, Unusual Whales, Capitol Trades and SentiSense compared: which has an API, which is free, and why every tracker can lag a trade by up to 45 days.
By SentiSense TeamThe Company KPI API returns the operating metrics a company reports about itself, such as iPhone revenue, AWS revenue, or Tesla deliveries, as quarterly time series with a filing citation on every series, for more than 900 US-listed companies.
By SentiSense TeamGive your OpenClaw agent a live market data feed in about two minutes: one free API key and one install command, and the agent you text from WhatsApp, Telegram or Discord can screen stocks, read sentiment, check who covers a name, and see who moved after earnings.
By SentiSense TeamGive Claude Code a live market data feed in about two minutes: one free API key and one command, and your agent can screen stocks, read sentiment, check who covers a name, and see who moved after earnings, instead of guessing from training data.
By SentiSense TeamEvery stock page now opens its Analyst tab with two readings side by side: the share of covering firms at Buy, Hold and Sell, and the SentiSense Score and Sentiment for the same name, today. The coverage API returns the firm counts as ratingBuckets, rating grades come back in one spelling, and a new Analyst Reaction insight names the firms that moved in the five sessions after earnings.
By SentiSense TeamAnalyst coverage is the set of research firms publishing ratings or price targets on a stock. SentiSense now returns it in one call for about a thousand US names: each firm's latest target and rating where it has one, the analysts it names, and the notes that arrived with no byline.
By SentiSense TeamRobinhood's MCP connector lets AI agents trade in a dedicated account. A builder's review: what it does well, what it leaves to the ecosystem, and the data that completes the pairing.
By SentiSense TeamUse a position size calculator to estimate how many shares fit your risk per trade and stop loss distance, with ATR context and delayed market data.
By SentiSense TeamGive your Grok Bot a live market data feed in about two minutes: one free API key, one install message, and your agent can screen stocks, read sentiment, and track insider and institutional activity on its own.
By SentiSense TeamGrok Bot review: what xAI's always-on agent does well, where it struggles, and what it can actually do with live market data.
By SentiSense TeamCapitol Trades has no public API, and the House and Senate Stock Watcher sites no longer resolve. Here is a documented congressional trading API, the endpoint mapping from the old bulk JSON dumps, and a working call.
By SentiSense TeamComparing the best stock data APIs in 2026: yfinance, Finnhub, Twelve Data, Tiingo, and SentiSense. Where each one wins, what the free options really cost you, and what matters when an AI agent is the caller.
By SentiSense TeamA stock screener API takes a structured filter and returns the matching rows in one call. Today we are opening ours: four deterministic endpoints over roughly a thousand tracked US names, free with an API key, so your agent or your script can run the same screens the app runs.
By SentiSense TeamThe Earnings Analysis API is live. It diffs the Risk Factors section of consecutive 10-K and 10-Q filings and returns excerpts of the passages a company added, removed, or rewrote, with a materiality score. It also returns a per-quarter earnings analysis report and a feed of which covered companies reported recently.
By SentiSense TeamA market sentiment index API returns a composite score, the date it covers, the scale it sits on, and the history behind it. One integration then renders every index a provider publishes, including the ones that ship later.
By SentiSense TeamThe /api/symbol history endpoints are internal to StockAnalysis, with no docs, no key, and no stability guarantee. Here is exactly what they return, the field-by-field mapping, and a documented OHLCV chart API with 26 years of history in one curl call.
By SentiSense TeamTwo ways to put live market data in front of an AI: a one-URL MCP connector for Claude, ChatGPT, and Grok, or an API key for code. Which fits an executive stock dashboard, the exact prompts to ask for a weekly briefing, and what the connector can and cannot do.
By SentiSense TeamAn entity sentiment API tracks sentiment, mentions, and scores for people, products, and organizations the same way a stock API tracks tickers. Here is how to query a CEO, a politician, or a flagship product in two calls.
By SentiSense TeamGet analyst ratings, consensus price targets, and upgrade and downgrade actions for any covered stock from one API, in Python or straight from your coding agent, then overlay real-time sentiment to see where the crowd disagrees with Wall Street.
By SentiSense TeamA financial news API for AI agents and LLMs: real-time stories, deduplicated, tickers tagged, sentiment scored. Why scraping RSS is the expensive path, and what to use instead.
By SentiSense TeamAn AI can write discounted-cash-flow math all day. What it cannot do is remember what a company actually earned. We connected Claude to reported financials and built a three-scenario DCF on META, without the model inventing a single number. Here is the full walkthrough.
By SentiSense TeamMost retail options data is either a raw chain you have to decode yourself or a paid flow terminal that costs more than a car payment. Today we are launching Options Intelligence: an options radar and a per-stock options tab that rank every reading against the stock's own history, free with a SentiSense account, plus a public API, an MCP tool, and an agent skill for builders. 'High IV' finally means something, because we tell you high relative to what.
By SentiSense TeamEveryone's building an AI agent to analyze stocks. When everyone has one, the agent stops being the edge and the data does. Here's how to feed yours better.
By SentiSense TeamRetail's real information edge is watching where the crowd talks about stocks before the talk shows up in price. The single largest place that conversation happens is finance YouTube, and until now almost nobody was measuring it. Today we are turning it into data: SentiSense reads finance YouTube as a first-class sentiment source alongside news, Reddit, X, and Substack, scored per video and per comment, linked to the tickers people are actually discussing.
By SentiSense TeamStock sentiment data providers and social sentiment APIs compared on Reddit and Stocktwits coverage, methodology, API access and price. Every price checked on the vendor's own page on October 13, 2026, including where each provider beats us.
By SentiSense TeamMarket sentiment moves prices before fundamentals do, but tracking it is vague advice unless you know what to measure. Here is a practical guide to the three ways people track stock market sentiment, what separates a useful signal from noise, and how to watch it for free.
By SentiSense TeamToday we are opening a third door into SentiSense: an MCP connector that brings our market intelligence straight into Claude and ChatGPT. Paste one URL, sign in, and your AI can pull Market Mood, stock sentiment, market-moving news, analyst ratings, and institutional flows. No API key, no code. Use the app. Build on the API. Or just ask your AI.
By SentiSense TeamA daily AI sentiment index from news and social conversation across a weighted basket of AI labs, products, chipmakers, and platforms, free to watch.
By SentiSense TeamTake-Two mention volume tripled before preorders opened, and coverage skewed positive. The harder question: has the stock already priced the win?
By SentiSense IntelligenceWe are launching the SentiSense Calendar API. The first feed is a forward-looking earnings calendar: which companies report over the next several weeks, with session timing, fiscal quarter, confirmation status, and consensus EPS. Free keys get a full week per call, next week included; PRO unlocks the whole forward window. Wired into the Python and Node SDKs plus our agent skills.
By SentiSense TeamWhen we launched the SentiSense API in March, PRO came with a 100,000 requests per month ceiling. We are removing it. PRO is now unlimited on monthly volume, with a single per-minute rate as the only guardrail. Here is what changed, why, and everything we have shipped for builders since launch.
By SentiSense TeamEvery few months a thread goes viral asking how Reddit's stock picks actually performed, and the answer is always a cherry-picked mess with no entry dates and the losers quietly forgotten. Today we are launching a free, survivorship-free tracker that answers the question honestly and keeps answering it: the stocks finance-Reddit turned bullish on, each frozen with an entry date and scored against the S&P 500.
By SentiSense TeamA weekly composite of how news and social media talk about the Fed Chair and the Federal Reserve, scored -100 to +100, free to view with no sign-up.
By SentiSense TeamToday we are formally launching the SentiSense API: a single, well-documented surface for stock fundamentals, institutional flows, congressional and insider trading, analyst ratings, AI insights, news sentiment, and our proprietary Market Mood index. Plus Python and Node SDKs, and an AI agent skill that drops into Claude Code, Cursor, and OpenClaw.
By SentiSense TeamCNN's Fear & Greed Index only looks at market data. Market Mood adds social sentiment from Reddit, X, and news, and it's completely free with full API access.
By SentiSense TeamDiscover how modern investors are using AI-powered data platforms to cut through market noise, make informed decisions, and augment their intelligence in an increasingly complex financial landscape.
By SentiSense TeamA practical guide to what works, what doesn't, and why most off-the-shelf solutions fail on financial text. Learn why fine-tuned models trained on news, X/Twitter, and Reddit outperform generic LLMs by 26%.
