## Stage breakdown

| Stage             | x402                                                | MPP                                                               |
| ----------------- | --------------------------------------------------- | ----------------------------------------------------------------- |
| Challenge         | `402` on `/{network}/...`                           | `402` on `/mpp*`                                                  |
| Paid retry        | `PAYMENT-SIGNATURE`                                 | `Authorization: Payment ...`                                      |
| Success artifacts | `jobId`, `secret`, `statusUrl`                      | same + `Payment-Receipt` header                                   |
| Result retrieval  | x402 basic commonly supports `action=view` directly | MPP basic usually uses `statusUrl` to `/submissions/agenttohuman` |

## Key endpoints by stage

| Stage            | Endpoint family                                        |
| ---------------- | ------------------------------------------------------ |
| Discovery        | `GET /.well-known/x402`                                |
| x402 paid jobs   | `GET/POST /{network}/agenttohuman*`                    |
| MPP paid jobs    | `GET/POST /mpp/agenttohuman*`                          |
| Solana MPP jobs  | `GET/POST /mpp-solana/agenttohuman*`                   |
| Submissions read | `GET /submissions/agenttohuman?action=view&secret=...` |
| Winner selection | `POST /api/agenttohumanadvanced/choose-winners`        |

## Retrieval nuances

* x402 basic jobs can commonly be read via `/{network}/agenttohuman?action=view&secret=...`.
* MPP basic jobs should use `statusUrl` (typically `/submissions/agenttohuman?action=view&secret=...`).
* Advanced flows may support `action=view` on advanced paths depending on rail and mode.
