Files and what's inside

Every file is Fonbet's own JSON, served unchanged inside the API envelope. Refresh: about every 1–3 s (live and pre-match in one file).

Pre-match markets by sport

Every bookmaker compared: sports and markets per bookmaker.

Field map: where each value lives

Paths start at data. The same file holds live and pre-match events; place tells them apart.

Real sample

An abridged record from site_livepre_fonbet.json: real values, most fields left out so the structure is readable. The downloads below keep every field.

• site_livepre_fonbet.sample.json — trimmed to a few events

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.

# Fonbet has no market names: odds are numeric factor ids per event.
# 921/922/923 = home / draw / away (inferred; checked against other books).
HOME, DRAW, AWAY = 921, 922, 923


def match_result(payload):
    """(event, 1, X, 2) rows for football matches in site_livepre_fonbet.json."""
    data = payload["data"]
    sports = {s["id"]: s for s in data.get("sports", [])}

    def sport_alias(segment_id):  # competition segment -> parent sport
        while segment_id in sports and sports[segment_id]["kind"] != "sport":
            segment_id = sports[segment_id].get("parentId")
        return sports.get(segment_id, {}).get("alias")

    factors = {cf["e"]: {f["f"]: f["v"] for f in cf["factors"]} for cf in data.get("customFactors", [])}
    rows = []

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: about every 1–3 s (live and pre-match in one file). Every response carries updated_at and a Last-Modified header; send If-Modified-Since to get 304 Not Modified when nothing changed.
• There are no market names in the file. Factor ids 921, 922 and 923 are home, draw and away — we verified them against other bookmakers' prices for the same matches. Other factor ids (totals, handicaps, double chance — they carry a line in pt) are not documented here.
• Sub-events (level 2 and 3) share the match's teams and start time; filter on level == 1 for the match itself.
• No Betradar id — cross-bookmaker matching needs team names and start time.
• This is a large file: request it with Accept-Encoding: gzip and send If-Modified-Since.
