For agents
ArbPlay has two products: a sure-bet web app for bettors, and the Odds HTTP API at https://api.arbplay.app, which serves raw odds from seven Greek bookmakers as JSON. Use the machine-readable files below — /llms.txt, /openapi.json and the JSON samples — instead of scraping pages.
Two products, two surfaces
The ArbPlay app is a real-time sports arbitrage service for the Greek market. It reads pre-calculated back/lay arbitrage rows that its scraper rewrites continuously and shows them to subscribers in a browser dashboard with optional Telegram alerts. Coverage is live and pre-match football, tennis and basketball across licensed Greek bookmakers (plus international and crypto books where they are legal), paired with betting exchanges (Betfair, OrbitX) and prediction markets (Polymarket, Kalshi) on the lay side. Its routes under arbplay.app/api/* (sign-in, the arbitrage feed, payments) serve the app only and are not a public API. Plan prices: /pricing.md.
The Odds HTTP API at https://api.arbplay.app serves the odds of Stoiximan, Novibet, Fonbet, Superbet, Elabet, OPAP (Allwyn) and Bwin exactly as each bookmaker publishes them. It is sold per bookmaker on RapidAPI, Zyla API Hub and JoJ API, or by direct key.
