HTTP API for Pet Simulator 99 game data, public player profiles, and authenticated player account access.
https://ps99.biggamesapi.io/
The v1 namespace (/v1/*) is the new surface covering authenticated player data, public player
profiles, clan aggregations, league seasons and leaderboards, the in-game event leaderboards, and the releases feed. See v1/overview.md for the full reference.
The legacy namespace (/api/*) is the original API — fully supported, not deprecated, and still
the right choice for pet data, item data, RAP, clan listings, and exists lookups. See
legacy/README.md for the full reference.

Every response from both /v1/* and /api/* uses the same envelope: a status field of "ok"
or "error", paired with either a data field or an error object.
{ "status": "ok", "data": { ... } }{ "status": "error", "error": { "message": "Rate limit exceeded.", "ignore": true } }Field-by-field details live in v1/overview.md.
v1 is shape-stable within the version: fields will not be renamed or removed without a major
version bump. Additive changes — new fields or new view keys in player profiles — are not
considered breaking and may appear at any time. Removals or renames bump to v2. The legacy
/api/* surface remains supported indefinitely. See
v1/overview.md for detail.
