What it does

The Refresh. REQUIRES ?url= on the paid request — a signed request without it is refused before the gate and no money moves. One fresh observation of your x402 endpoint by the weekly census's own instrument, right now instead of next Sunday — folded into your endpoint passport wherever it is newest, which moves the passport's freshness state (and the free embeddable chip that decays with it) back to fresh.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/26425.json for the price and payment options.
Pay. Call GET https://scvd.store/api/buy/passport_refresh. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.
