Matchbook: the honest guide

Matchbook, founded in 2004, made its name on US sports and has grown into a serious racing exchange with sharp pricing and a 2% commission. For developers and tool users it has a unique selling point: the API is open to every customer — no key, no application, no access fee.

What it is, and who it suits

Matchbook targets sharper recreational and professional bettors: strong horse-racing markets, genuine depth on US sports (NFL, NBA, MLB), and competitive football pricing. It suits racing traders wanting a value alternative and anyone trading American sports on an exchange.

Strengths

• Low commission, simply applied. 2% on net winnings for UK, Ireland, Channel Islands and Isle of Man customers (4% elsewhere), with commission-free "Matchbook Zero" promotions on selected markets from time to time.
• US sports depth that the other three don't match, alongside solid UK/IE racing liquidity.
• The easiest API access of any exchange. Any registered customer can use the API immediately with their normal login — no application key, no vetting queue, no upfront fee. Full market depth is available through it.

Weaknesses

• Overall liquidity is behind Betfair; outside racing, US sports and bigger football matches, books can be thin.
• Usage-based API pricing. Instead of an access fee, Matchbook charges for data volume: £100 per 1,000,000 GET requests in a calendar month, deducted from your account balance (write requests — placing and cancelling bets — are free at reasonable frequency). A fast price poll adds up: heavy all-day, every-day polling can reach millions of requests a month, so active users should watch their usage (Matchbook's api@matchbook.com can report it).
• REST-only API — no streaming feed; data arrives by polling, as with Betdaq and Smarkets.

Commission and charges

• 2% of net winnings per market (UK, Ireland, Channel Islands, Isle of Man); 4% for other territories; occasional 0% promotions on selected markets. No published high-winner surcharge.
• API usage: £100 per 1M GET requests per calendar month; writes free at reasonable frequency. Source: Matchbook's API pricing page.

Getting API access, step by step

(Process per the Matchbook Developer Centre, checked 9 August 2026.)

1. Open a Matchbook account at matchbook.com and complete verification (18+, KYC).
2. That's it — there is no key or application. The API accepts your ordinary account credentials immediately. (This is the lowest barrier to entry of the four exchanges.)
3. Understand the metering: GET requests are counted per calendar month and billed at £100 per million from your account balance; write requests are free at reasonable frequency. Email api@matchbook.com for usage details or plan upgrades.
4. Connect in BetTrading.net: add Matchbook on the connections screen with your Matchbook credentials — see Connecting your exchanges.

• Full-depth ladders — Matchbook's price API returns multiple levels per side, feeding BetTrading.net's Ladder view properly.
• Strong history data — genuinely date-ranged settled-bet records make Matchbook (with Betfair) the best-served exchange in Trade History and Positions & P&L.
• Racing value leg — with price routing, Matchbook's racing prices at 2% commission regularly beat the bigger book's after costs.
