Guides
Practical, code first guides to working with bookmaker odds data. How to pull prices, stream them live, and build on top of the RapidOddsAPI feed.
What you can build with an odds API
The betting tools developers build on a live odds API: positive EV scanners, arbitrage finders, middles tools, bonus and matched betting tools, and live odds screens.
June 2026GuideBuild an arbitrage betting scanner in Python
A working arbitrage scanner in under 70 lines of Python. Pull head to head odds from many bookmakers, check every pair for an arb, and split the stake.
June 2026GuideBuild a middles scanner in Python
Find middle bets on totals across bookmakers. Back the Over at a low line and the Under at a high line, and win both if the result lands in the gap.
June 2026GuideTurn a bonus bet into cash with Python
Convert a stake not returned bonus bet into near guaranteed cash. Place the bonus on the long price, hedge the other side at another book, and keep the retention.
June 2026GuideBuild a positive EV scanner in Python
Find value bets by de-vigging a sharp book like Pinnacle to get a fair price, then scanning every other bookmaker for prices that beat it.
June 2026GuideBuild an odds comparison screen in Python and HTML
Show every bookmaker price for each game side by side and highlight the best one. A Python backend pulls the odds, a plain HTML and CSS page draws the grid.
June 2026GuideMatching games across bookmakers in Python
Reliably tell when two bookmakers are pricing the same game. Handle doubleheaders and different listed start times by matching on teams plus a time window.
June 2026GuideHow to pull bookmaker odds with a REST API
Fetch live bookmaker odds over a simple REST endpoint. Parameters, response shape, and credits, with working Python, JavaScript, and cURL examples.
June 2026GuideHow to stream bookmaker odds with WebSocket
Receive live bookmaker odds the moment they change with a WebSocket feed, instead of polling a REST endpoint on a timer. Full Python and Node.js examples.
June 2026GuideREST vs WebSocket for odds data: which should you use?
Polling a REST endpoint or streaming over a WebSocket. How the two approaches differ for bookmaker odds, and how to pick the right one for what you are building.
