Key differences
| Category | Odds API | BoltOdds | Why? |
|---|---|---|---|
| Latency & Delivery Model | Both APIs emphasise low-latency real-time delivery via WebSocket feeds—Odds-API.io offers WebSockets alongside REST endpoints, while BoltOdds is WebSocket‑first—so on paper neither has a clearly documented speed advantage. ([docs.odds-api.io](https://docs.odds-api.io/guides/websockets)) | ||
| Bookmaker & Market Coverage | Odds-API.io explicitly advertises real-time odds from 250+ bookmakers across more than ten sports and roughly 100+ market types, whereas BoltOdds lists many sports and sportsbooks but does not publish a comparable global bookmaker count. ([docs.odds-api.io](https://docs.odds-api.io/api-reference/introduction)) | ||
| Event Data Depth | BoltOdds’ Pro tier specifically adds live play‑by‑play feeds and live/historical box scores for select leagues, whereas Odds-API.io’s public docs focus on odds, fixtures, and scores rather than full play‑by‑play feeds. ([boltodds.com](https://boltodds.com/pricing)) | ||
| Historical & Analytical Features | Odds-API.io exposes historical closing odds, detailed odds-movement history, and dedicated value‑bet/arbitrage endpoints, while BoltOdds mainly offers live odds plus box scores and leaves most analytical logic to the client. ([docs.odds-api.io](https://docs.odds-api.io/api-reference/historical/get-historical-odds)) | ||
| Pricing | Odds-API.io provides a documented always-on free tier around 5,000 requests/hour plus low-cost paid plans via RapidAPI that start well under $100/month, while BoltOdds’ listed plans begin at $99/month after a short free trial. ([libraries.io](https://libraries.io/pypi/odds-api-io)) |
Feature comparison
| Feature | Odds API | BoltOdds | Notes |
|---|---|---|---|
| Real-time access model (WebSocket vs REST) | Odds-API.io supports both REST polling and WebSocket streaming for odds, while BoltOdds is WebSocket‑first for real-time data with example async clients in its docs. ([docs.odds-api.io](https://docs.odds-api.io/guides/websockets)) | ||
| Official SDKs & client libraries | Odds-API.io publishes official SDKs (for example in Python and other languages) to simplify integration, whereas BoltOdds currently shows raw WebSocket code samples but no official language‑specific SDKs. ([libraries.io](https://libraries.io/pypi/odds-api-io)) | ||
| Player props coverage | Odds-API.io explicitly supports extensive player props markets across major US sports, while BoltOdds does not clearly specify props coverage in its public marketing or docs. ([docs.odds-api.io](https://docs.odds-api.io/examples/player-props)) | ||
| Value-bet / arbitrage helper endpoints | Odds-API.io offers dedicated value‑bet and arbitrage endpoints and SDK helpers so you can query precomputed opportunities, whereas BoltOdds focuses on raw odds streams and expects you to compute EV yourself. ([libraries.io](https://libraries.io/pypi/odds-api-io)) | ||
| Free tier / free trial | Odds-API.io markets an ongoing free tier with roughly 5,000 requests per hour and full endpoint access, whereas BoltOdds offers a 14‑day free trial before requiring a paid plan and any persistent free tier is unclear. ([libraries.io](https://libraries.io/pypi/odds-api-io)) | ||
| Global bookmaker coverage (200+ sportsbooks) | Odds-API.io states coverage from 250+ bookmakers across many sports, while BoltOdds lets you subscribe to “all sportsbooks” but does not publish a concrete global bookmaker count. ([docs.odds-api.io](https://docs.odds-api.io/api-reference/introduction)) | ||
| Historical odds & line history | Odds-API.io documents endpoints for historical closing odds and full odds‑movement history, whereas BoltOdds advertises historical box scores but not historical odds lines. ([docs.odds-api.io](https://docs.odds-api.io/api-reference/historical/get-historical-odds)) | ||
| Play-by-play & box-score feeds | BoltOdds’ Pro plan includes live play‑by‑play feeds and live/historical box scores for select leagues, a capability not prominently described in Odds-API.io’s public feature list. ([boltodds.com](https://boltodds.com/pricing)) |
