# Create a quota

> Creates a project-scoped quota. `requests` is valid for `scope: project`/`api_key`; `tokens` and `cost_usd` are valid for `scope: project`/`agent`/`actor`; `storage_bytes` is valid for `scope: project` only. Any other scope/metric pair is rejected with 400 (no attribution exists to enforce it). An `actor` quota caps one end user's spend, matched from the generation's session; a null `scope_ref` means one budget *per* actor rather than a pooled project total. A `cost_usd` quota may name one `meter_type` to cap; omitting it caps every priced meter. A duplicate quota (same project, scope, scope_ref, metric, window, meter_type) is rejected with 409.

Creates a project-scoped quota. `requests` is valid for `scope: project`/`api_key`; `tokens` and `cost_usd` are valid for `scope: project`/`agent`/`actor`; `storage_bytes` is valid for `scope: project` only. Any other scope/metric pair is rejected with 400 (no attribution exists to enforce it). An `actor` quota caps one end user's spend, matched from the generation's session; a null `scope_ref` means one budget *per* actor rather than a pooled project total. A `cost_usd` quota may name one `meter_type` to cap; omitting it caps every priced meter. A duplicate quota (same project, scope, scope_ref, metric, window, meter_type) is rejected with 409.

`storage_bytes` caps a stored total rather than a windowed one, so it takes `window: current` and every other metric refuses that value (400 either way). It is enforced at the corpus write paths — file upload and create, document create, document ingest and re-ingest, memory-entry create — with `409 QUOTA_STORAGE_EXCEEDED` and no `Retry-After`, since no window reset clears a footprint.
