OPAP Odds API (Allwyn / OPAP Store)

OPAP, part of the Allwyn group, is Greece's national betting operator. The data is the Allwyn store offer (formerly OPAP Store): the odds you bet on in an Allwyn shop, with each pre-match event's store code. OPAP's separate online sportsbook is not part of this API. The marketplace listings are named Allwyn Odds and OPAP Store Odds API.

• site_live_opapstore_soccer.sample.json — trimmed to a few events
• site_pregame_opapstore_soccer.sample.json — trimmed to a few events
• site_pregame_opapstore_basketball.sample.json — money line, point spread and total points, with store codes

Each download is a complete GET /v1/data/{filename} response cut down to a few events, with every id reference still resolving. All samples are listed in samples/index.json.

Extract match-result (1X2) odds in Python

This function is tested against the samples on this page. Pass it the parsed JSON response.

    rows = []
    for ev in payload["data"].get("data", {}).get("events", []):

Through a marketplace

On RapidAPI, Zyla API Hub or JoJ API you call the marketplace's gateway with that marketplace's key. The two endpoints and the JSON they return are the same; copy the base URL and path from the listing.

Freshness, gaps and caveats

• Refresh: live files about every 1–3 s, pre-match files about every 4–7 s. Every response carries updated_at and a Last-Modified header; send If-Modified-Since to get 304 Not Modified when nothing changed.
• Not every event carries every market: many pre-match events list only totals and other markets without a MATCH_RESULT market — check groupCode.
• The line is part of the market name ("Total Goals Over / Under 2.5"). handicapValue equals the line for totals, but Asian handicaps use quarter-goal units there (a −1.25 line is -5.0) — read the line from the name.
• Outcome order inside a market is not fixed — read subType (H, D, A) instead of the position.
