Free odds APIs: what you can try without paying
Zero-signup access to live odds, as measured in the September 2026 OddsBench run.
Almost no live odds API is genuinely free. 3 of 32 feeds let you try live odds with no signup, no card and no sales call: PinnWire, OddiWire and FanLine Wire — each publishes a public demo key. The other 29 require an account or a sales contact before they return data.
| Provider | Feed | Protocol | Line-change p50 | Line-change p95 | Error rate | Unlimited real-time push |
|---|---|---|---|---|---|---|
| PinnWire | Pinnacle line stream (WebSocket) | WebSocket | 145 ms | 286 ms | 0.02% | $178/mo |
| OddiWire | ODDIN.GG esports feed (REST + SSE) | SSE | 212 ms | 457 ms | 0.04% | $299/mo |
| FanLine Wire | FanDuel line feed (REST + WebSocket) | WebSocket | 233 ms | 521 ms | 0.02% | $149/mo |
Prices as of 2026-09-13 — the pricing page of every listed vendor was re-read on that date, and every price change is logged in the runs changelog. Re-pricing changes prices only: the measured results in this run are frozen.
What the demo keys give you
- Live odds, no contract. "Try without signup" means a public demo key or open endpoint that returns live odds with no account — the same standard applied to every row of the main table.
- A real evaluation surface. Enough to test freshness from your own servers, check the payload shape and watch how the feed behaves during a line move.
- A fair baseline. Each is measured on the same probes as every other feed, and their numbers sit in the same open dataset.
What paid access costs
A demo lets you evaluate a feed, not run a product on it. The cheapest unlimited real-time plan measured this run is FanLine Wire at $149/mo; 20 of 32 feeds publish no unlimited real-time push price at all — REST-only, metered, pre-match or quote-only, with the reason stated on the row. The full price picture is on the measured comparison and in the FAQ.
How to test a demo feed in an afternoon
- Measure from your own servers. Network distance dominates latency; the methodology shows how a line change is timed.
- Watch a whole day. Count reconnects and stale prices around kickoff and settle windows, not just the first minute.
- Check your books and markets. A feed fast on one league can be thin on another; the per-sportsbook pages list what each feed carries.
- Read the payload. Odds formats, suspension flags and market depth differ between vendors — the demo shows exactly what ships.
