Feed status

Feed header, per-file load report, and static-join statistics.

GET /api/feed

The diagnostic endpoint. header.timestamp is when the agency generated the feed — the instant every prediction in the API is relative to.

files.detail reports each protobuf file separately, so a feed that silently failed to decode is visible as a failed count rather than looking like an agency that happens to run no buses.

static describes the GTFS join that gives ids their names. available: false there means route and stop names are missing everywhere and routeId coverage collapses to under 1% — see The static join.
