SentiSignalChart Analysis API — AI Price-vs-Sentiment Analysis in One Call

Chart Analysis API — AI Price-vs-Sentiment Analysis in One Call

Give the API an asset and a time window, get back a written analysis comparing how the price moved against how sentiment shifted over that window — the same AI chart analysis shown on SentiSignal’s own asset pages, now available directly to your application.

Endpoint: GET /api/v1/chart-analysis
Auth: same API key as the rest of the SentiSignal API (Authorization or x-api-key header).
Parameters: asset_type (crypto/commodity/fx, default crypto), symbol (required), period (e.g. 7d, 30d, 1y, default 7d).

What you get back

A short written analysis of how price and sentiment moved together over your chosen window, plus the exact time range and data granularity used to produce it. Very long windows (a year or more) automatically use coarser data so the analysis stays focused, rather than being refused. If there is genuinely no price or sentiment data for the asset in that window, you get a clear message saying so — never a fabricated analysis.

What you will never get back

A raw, structured price series — for any asset. This endpoint only ever returns a written analysis, never a raw price table you could plug into your own charting. For cryptocurrency specifically, this also satisfies our Binance/ CoinMarketCap licensing terms, which restrict redistributing their raw data feed — the written analysis may still mention real price figures narratively (current price, how it has moved over your requested window), since that is our own generated content, not a redistribution of the underlying feed. Metals, FX, and commodity prices — already available elsewhere in this API — work exactly the same way.

Limits

  • This endpoint is available on every plan — there is no functional restriction by plan.
  • Because each analysis involves an AI-generated write-up, it counts against its own separate monthly usage limit (shown in the response headers), independent of your general API request limit. Higher plans include a larger monthly allowance.
