Create a the billing provider checkout session

POST 
/api/v1/credits/checkout

Create a the billing provider custom checkout session for purchasing credits.

The caller's organization public_id and user public_id are embedded as metadata on the billing provider checkout so the webhook receiver can route the eventual credit grant back to the right tenant.

• Scope required: billing:manage.
• Role required: manager or above on the organization.
• Rate-limit tier: billing (10/hour per user).
• Returns 501 if the billing provider is not configured in this environment.
• Returns 502 on any non-201 response from the billing provider API.

200

Successful Response

400

Bad request — malformed input or failed validation.

401

Missing, expired, or invalid credentials.

403

Authenticated but not authorized for this resource. Note: cross-organization reads return 404, not 403.

404

Resource not found, or hidden for tenant-enumeration safety (the caller lacks permission to know whether the resource exists).

409

Conflict — the current resource state does not allow this operation (e.g. assessment already started, email already in use).

422

Semantic validation failure — request shape was valid but contents were not.

429

Too many requests — rate limited. Retry after the window resets.

500

Internal server error — unexpected failure.
