How do I make my first API call?

1. Get a free key at app.sentisense.ai/get-api-key. Keys start with ss_live_.
2. Send it in the X-SentiSense-API-Key header on every request:

curl -H "X-SentiSense-API-Key: ss_live_YOUR_KEY" \
  "https://app.sentisense.ai/api/v1/stocks/price?ticker=AAPL"

3. The response is JSON. A 401 means the key is missing or wrong. A 404 can mean a ticker we do not track, no data of that kind for the ticker, or a wrong endpoint path. The error code in the response says which (see why the API returns a 404).

Next steps

• Python or Node. Install the SDK with pip install sentisense or npm install sentisense. Examples are in the API quickstart.
• Use it from an AI assistant instead. Connect SentiSense to Claude, ChatGPT or Codex with the MCP connector, with no key to paste.
• Find the data you need. The API reference lists every endpoint. Some return a preview on the free plan: see why data says preview.
