       description: 'Starts an agent credit purchase paid with a Machine Payments Protocol (MPP) credential: USDC on Tempo, or a card when one is offered. The first call answers `402` with one `WWW-Authenticate: Payment ...` challenge per payment option; pay one of them and retry the same request, same `Idempotency-Key`, with the signed credential in `Payment-Authorization: Payment ...` (or in `Authorization: Payment ...` when the management key is sent as `X-Api-Key`). A paid request answers `202`: the transfer was broadcast or the card was charged, and the payment is still being confirmed, so credits arrive asynchronously. Poll the URL in the `Location` header, `GET /api/v1/credits/purchases/{id}`, until `status` is `credited` or `failed`.'
