The response contains the **full key exactly once** — copy it immediately; it can't be retrieved later. The key carries `read`, `write`, and `admin` permissions and does not expire. **One key per organization for now:** if a key already exists, creation fails with `409 KEY_LIMIT_REACHED`. To rotate, delete the old key (see `DELETE /api-keys/{keyId}`) and create a new one — the old key stops working the moment you delete it, so update your backend configuration in the same maintenance window. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/organization/api-keys openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing.
