Comparison
OddsRelay vs OddsJam
How you buy is the first difference here. OddsJam's consumer product deserves its reputation, but its API is a different door: sales-gated behind a contact form, docs served under sibling brand OpticOdds, raw prices with no back-to-exchange-lay pairing documented. OddsRelay's odds data API delivers UK prices with the matching already done, each back price paired to an exchange lay and rated.

- Rating
- 102.4%
Paired and liquidity-gated, with the lay price and liquidity carried. The rating here is one line of client-side maths at your own commission rate (at 0: 100 × back ÷ lay). You render the row.
What OddsJam does well
- A genuinely strong consumer product: arbitrage, positive-EV, promo-conversion and middles tools, a mobile app and a 7-day free trial.
- Serious US breadth: the consumer site states 150+ sportsbooks, with US-led sports coverage: NFL, NBA, MLB, NHL, college football and basketball, soccer and golf.
Side by side
| Dimension | OddsJam | OddsRelay |
|---|---|---|
| Core output | Raw odds per sportsbook: prices its API page bills as real-time, player props, a historical odds database, JSON/XML with push streaming. Pairing, rating and any matching are your build. | Back prices arrive already paired to a live exchange lay price and rated: oddsmatcher-ready. |
| Bet365 | Listed on the developer sportsbooks page as one raw source among roughly 300+; pairing it against an exchange price is your work. | Covered across all six feed types, already matched. |
| UK bookmaker depth | The developer list includes major UK names (Ladbrokes, Coral, William Hill, BetVictor, Unibet (UK)), but the API pages document no UK regional coverage. | 140+ bookmakers across a 20-country network (UK and Irish books plus the African, Australasian and North American domestic names big aggregators skip), normalised into one schema and live on the coverage dashboard. |
| Exchange lay prices | Available as raw individual sources, Betfair Exchange (with explicit lay-price sources) and Smarkets, unpaired to any back price. | Lay prices with liquidity from four exchanges (Betfair, Smarkets, Matchbook and BETDAQ), pre-paired to every bookmaker back price and rated. |
| Regions beyond the US | Does not list a South Africa or Nigeria region; of the common SA books only Supabets appears, and Bet9ja, SportyBet and BetKing are not listed. | A 20-country coverage network (the UK, Ireland, South Africa, Nigeria, Kenya, Ghana, Tanzania, Uganda, Zambia, Cameroon, Côte d'Ivoire, Senegal, DR Congo, Mozambique, Malawi, Australia, Canada, the US, Rwanda and New Zealand), region-filtered from one endpoint. |
| Pricing posture | Sales-gated: the API page says "Contact us now to get premium access and pricing" and publishes no tiers. | Scoped per client: a trial key first, then a plain conversation. No contact-form wait. |
| Docs and API access | Developer docs are publicly viewable at developer.opticodds.com (where developer.oddsjam.com redirects); a licence key is requested via a contact form; no self-serve signup is described. | Public docs, no login wall, and a self-serve trial key that puts the matched feed in your product the same day. |
When OddsJam is the better buy
For a US-facing product, OddsJam's ecosystem is hard to argue with: polished, widely-used consumer tooling and, behind the API door, breadth a UK-first feed doesn't try to match. If a sales-led procurement process suits you, it is a credible, enterprise-scale choice.
One structural note: developer.oddsjam.com now permanently redirects to developer.opticodds.com, so the OddsJam API and OpticOdds are effectively one product with two front doors. The developer-level facts here are cited to the OpticOdds pages where they now live.
Pick OddsJam if
- Your product is US-facing and needs its breadth of US sportsbooks and player-props coverage.
- You want push streaming and a historical odds database for modelling or backtesting.
- The consumer tooling is the point, not the API.
- You are comfortable with sales-led procurement and want an enterprise-scale supplier.
Pick OddsRelay if
- Your oddsmatcher needs rows that arrive already paired and rated.
- Bet365 matched against exchange lay prices is the requirement.
- You want to evaluate self-serve: public docs and a trial key the same day, no contact form.
- You want UK depth now, plus African, Australasian and North American domestic books from one region-filtered endpoint.
