The UK odds APIs, compared
Six odds APIs a UK product might build on, set side by side on the questions that decide the purchase: which UK bookmakers they carry, whether bet365 is among them, whether exchange lay prices arrive paired or raw, and how you buy. Every fact below was read on the provider's own pages in September 2026 and is linked to its source.
OddsRelay publishes this page and is one of the six entries. The entries are in alphabetical order, and each says who it suits rather than being ranked.
Who each one suits
BetsAPI
A long-running, low-priced source of raw data built around bet365, sold per sport, per bookmaker or all-inclusive.
Consider it if you want low-priced raw bet365 data with results and years of history, and you will build the processing yourself.
| UK bookmakers | Five bookmaker-specific odds APIs with all markets (bet365, Betfair, BWin, Sbobet and 1xBet); its aggregated Events API accepts 40 bookmaker sources, UK books among them, for 1-3 main markets per sport. |
|---|---|
| bet365 | Its flagship, documented endpoint by endpoint. |
| Exchange lay prices | Betfair Exchange endpoints whose responses carry back and lay prices with size; pairing them to bookmaker prices is your build. |
| Output | Raw events, odds and results per bookmaker. |
| Delivery | REST, with the token passed in the URL query string. |
| Pricing | Published self-serve prices with low-priced paid trials; its pricing FAQ says it offers no free trials. |
| Docs | Fully public, no login wall. |

|---|---|
| bet365 | Listed, delivered as raw prices. |
| Exchange lay prices | Betfair Exchange and Matchbook with raw back and lay odds; pairing is your build. |

OddsRelay
A UK & Ireland odds feed that arrives already matched: every bookmaker back price paired to an exchange lay price, with the lay liquidity attached.
Consider it if you are building a UK oddsmatcher, comparison site or matched-betting product and want bookmaker prices already paired against exchange lay.
| UK bookmakers | 140+ bookmakers · 60+ live in the UK & Ireland, in one schema, live on the coverage dashboard. |
|---|---|
| bet365 | Included, across all six matched feed types. |
| Exchange lay prices | Lay prices and liquidity from the four UK exchanges (Betfair, Smarkets, Matchbook and BETDAQ), pre-paired to every bookmaker back price. |
| Output | Six matched feed types (Standard, Each-way, Extra place, Best odds guaranteed, Dutching and 2Up) and a raw per-book feed. |
| Delivery | REST, polled pre-match rather than streamed in-play, with ETag/304 and gzip. |
| Pricing | Published plans (Free, Starter, Pro and Business), with Enterprise quoted. Every plan gets every product and bookmaker its region serves; plans differ only in tokens. |

OpticOdds (also the OddsJam API)
The enterprise incumbent: fast, broad raw odds for operators and traders. OddsJam's developer docs redirect to it, so the two are one API with two front doors.
Consider it if you run a sportsbook, trading desk or platform and need in-play speed and source breadth, through a sales-led process.
| UK bookmakers | UK names appear in its developer-docs table, labelled per book; it documents no UK region. Its homepage states 200+ sportsbooks. |
|---|---|
| bet365 | Not in its public developer-docs reference table (refreshed September 2026); its docs point to a key-gated endpoint for the live list. |
| Exchange lay prices | Betfair Exchange (with separate lay sources) and Matchbook as raw sources, unpaired to bookmaker prices. |
| Output | Raw odds, plus an odds screen, bet builder and trading tooling. |
| Delivery | A push stream built for in-play. |
| Pricing | Sales-gated: a request-pricing form with no published tiers. |
| Docs | Public, no login wall, with published rate limits. |

The Odds API
A long-running self-serve source of raw odds, operating since 2017 by its own account, across many sports and regions.

| UK bookmakers | Lists 21 UK-region bookmakers and exchanges; its homepage states 100+ bookmakers across all regions. |
|---|---|
| bet365 | Not listed in its UK region; listed only in its Australia region. |

How this page was checked
Each fact was checked on the provider's own public pages on 18 September 2026, and absences are stated only where the page that would list the item was read. Prices are described rather than quoted, because they change faster than this page. Where a provider's pages disagree with each other, the entry says which page it cites.
Questions
Which UK odds APIs include bet365?
OddsRelay, OddsPapi, BetsAPI and UK Odds API list bet365. The Odds API lists it only in its Australia region, not its UK one. OpticOdds' public reference table, refreshed in September 2026, does not list it, though its docs point to a key-gated endpoint for the live list.
Which UK odds APIs pair bookmaker prices against exchange lay?
Of these six, OddsRelay delivers bookmaker back prices already paired to an exchange lay price. BetsAPI, OddsPapi, OpticOdds and The Odds API supply exchange prices as raw sources for you to pair, and UK Odds API's documented rows carry one price per outcome per bookmaker, with no separate lay price.
Is there a free UK odds API?
The Odds API, OddsPapi, UK Odds API and OddsRelay each publish a free tier or plan. BetsAPI sells low-priced paid trials and says it offers no free trials. OpticOdds is sales-gated, with a free trial mentioned but no self-serve signup documented.
