About OddsBench

OddsBench is an independent, continuously run benchmark of sports odds API latency. It exists because every latency number in this industry was, until now, published by the vendor selling the feed.

Who runs it

OddsBench is operated by Marek Nowak, a Warsaw-based data engineer who has built trading and line-monitoring systems for sports betting since 2019. Contact: [email protected]. Corrections: [email protected].

Funding and independence

• Self-funded. Server and API costs for the 2026-09 run: approximately $4,800.
• No affiliate links, no sponsored rows, no paid placement, no consulting relationships with listed providers.
• Every API key is purchased at the stated tier; providers are not told when a run is in progress.
• We do not accept referral fees and we do not accept data partners. No listed provider pays us anything in any form — not for a listing, a ranking, or access to our data. Anyone who joins the project with a commercial relationship to a listed provider is disclosed here by name.

Open data

Per-provider measurements for every run are downloadable as CSV and JSON under Runs, licensed CC BY 4.0.

Adding a provider

Any provider with a self-serve or trial plan can be added. Email the endpoint and plan tier; there is no fee and no way to opt out once listed.
