For arbitrage & trading tools
Odds data for arbitrage and trading tools.
Arbitrage and trading tools live or die on freshness and breadth. You need many books in one shape, current enough to act on, with exchange prices alongside. OddsRelay delivers that as one clean API — deep UK coverage, bet365 included, exchange back/lay context, on a tight refresh cycle you can design around.
The job to be done
Detect cross-book and back/lay discrepancies across a wide, current market picture — without building the collection and normalisation that makes detection possible.
The data you need
Breadth across books
The more books in one consistent shape, the more discrepancies your tool can surface.
Freshness you can design around
A tight, stated refresh cycle and a timestamp on every payload, so detection runs on current prices.
Exchange back/lay context
Exchange prices alongside bookmaker odds, the reference your calculations need.
A normalised schema
Every book mapped to one event and selection model, so a cross-book comparison is a direct lookup.

- Exchange back/lay prices sit alongside bookmaker odds for back/lay calculations.
- A tight, timestamped refresh cycle lets you reason about how current each price is.

Questions
How fresh is the feed?
It refreshes on a tight cycle and stamps every payload with a processed-at time, so you always know how current a price is. Live freshness is published on the coverage dashboard — we publish what we can stand behind rather than a marketing number.
Do you provide exchange prices?
Yes — exchange back/lay prices are available alongside bookmaker odds, which is what back/lay and arbitrage calculations need.
Is bet365 included?
Yes — bet365 is included, adding a widely-followed book to your detection set.
Can your feed guarantee an arbitrage is still there when I act?
No feed can — prices move. What OddsRelay provides is a wide, current, timestamped market picture so your tool detects opportunities on the best available data; acting on them is your tool's job.
