Coverage you can
verify before buying.

Swap the feed, keep the contract.

Coverage is not uniform, and we publish that rather than hide it. Fixtures and results reach far more competitions than match statistics do: a competition can carry results while carrying no corners, shots or possession. Every statistics response therefore states coverage.statistics_available for the match you asked about, so an uncovered competition returns an explicit answer instead of an error. OpenFootball’s community-maintained CC0 data remains a historical bootstrap, not a live feed. The beta serves each dataset as Stats API observed it at the latest successful ingestion, with no promised maximum age or refresh interval. GET /api/v1/coverage/summary reports that ingestion and artifact-retrieval time, while source_updated_at stays null and freshness_guaranteed stays false.

Source mappings support reviewed provider migrations. Unique reschedules and corrections can keep a stable ID; ambiguous matches are never guessed. If a fixture disappears from a complete snapshot, it is hidden as an inactive tombstone rather than mislabeled as canceled, and the same ID is restored if it reappears.
