Notes on markets, sentiment, and building an AI research platform in public.
Give 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 TeamWe compared Quiver Quantitative, Unusual Whales, Capitol Trades, and SentiSense for tracking congressional trades. Here is where each one wins in 2026.
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 TeamFive stock sentiment data providers compared on coverage, methodology, API access, and price, plus the commodity data APIs, and where each one 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 TeamOur sentiment data caught the hype tripling before preorders even opened. The harder question is whether Take-Two's stock has 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.
