The crowd, as an API

Every call on BitPredict is a real prediction with a real timestamp. This endpoint serves the live crowd read per asset — price, bull/bear split, 24h accuracy, and call volume — as one cacheable GET. Free while in beta, no key required — and API keys are now live for Elite members.

Live sentiment endpoint

One asset per request, any catalog symbol (BTC, ETH, SOL, …). Responses are CDN-cached for 60 seconds and CORS-open, so you can call it straight from a browser.

GET https://app.bitpredict.io/api/public/sentiment/BTC

Example response

{
  "symbol": "BTC",
  "name": "Bitcoin",
  "priceUsd": 97231.12,
  "change24hPct": 1.84,
  "sentimentUpPct24h": 68.42,
  "sentimentDownPct24h": 31.58,
  "crowdAccuracy24hPct": 54.9,
  "predictions24h": 1204,
  "totalPredictions": 48210,
  "asOf": "2026-07-06T14:00:00.000Z"
}

sentimentUpPct24h / sentimentDownPct24h — the trailing-24h crowd split; falls back to the all-time split until enough recent calls exist, and is null before any calls at all.
crowdAccuracy24hPct — how the crowd actually scored on calls settled in the last 24h. We publish it either way.
Unknown symbols return 404.

Settlement is public too: how settlement works documents the methodology and the digest endpoints anyone can re-hash.

Embeddable gauge

The same data as a live SVG card — drop it into any site with a plain img tag. It updates on the same 60-second cadence. Append ?theme=light for light pages.

API keys — Elite

Elite members can create API keys to authenticate their requests. Send the key in the x-api-key header (or Authorization: Bearer bp_…). Keyed requests skip the shared 60-second cache — every response is served fresh with Cache-Control: private, no-store — and include a keyTier field. The keyless endpoint above stays free while in beta, unchanged.

curl -H "x-api-key: bp_live_YOUR_KEY" https://app.bitpredict.io/api/public/sentiment/BTC

Fair use

Free while in beta for dashboards, bots, and posts — attribution appreciated. The data is a snapshot of a prediction game, not financial advice. API keys are live for Elite members; more endpoints (per-asset history, leaderboards) are on the roadmap.
