# SCVD General Store – Passport Refresh

> SCVD General Store – Passport Refresh is a paid API for AI agents from scvd.store, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).

Triggers an immediate on-demand re-probe of your x402 endpoint by the weekly census instrument, updating your endpoint passport and its embeddable freshness chip to reflect the latest observation right now rather than waiting for the next Sunday census.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scvd-general-store-passport-refresh-5d433003
```

Example prompt: I just fixed a bug on my x402 endpoint at https://myapi.example.com/pay — can you trigger an immediate passport refresh on it so the freshness chip updates now instead of waiting until Sunday? Put 'post-fix verification' as the purpose and label it 'MyAPI Agent'.

## When to prefer this

Use this endpoint when you own or operate an x402 endpoint and need its passport freshness chip updated immediately — for instance after a fix, before sharing credentials with a partner, or after maintenance — rather than waiting up to 7 days for the next weekly census cycle. This is the only way to get an out-of-cycle signed observation from the official census instrument. Do not use it to probe endpoints you do not own, or to check conformance of x402 offers and receipts (use the conformance checker sibling endpoint for that).

## Known failure modes

- Endpoint URL points to scvd.store's own hostname — refused by design
- Endpoint URL is not publicly reachable or uses a non-default port — passport updates to broken/unreachable state (not an error, but expected behavior)
- Invalid URL format supplied — schema validation failure
- Payment of $1 USDC not completed — endpoint not called
- Probe finds endpoint broken — passport and chip update to dark/broken state (this is the product working correctly, not a failure)

## How this service works

The Refresh. 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. Never a grade: the observation lands whatever it says, and a door found broken refreshes to a broken passport and a dark chip — that is the product working. The observation is signe…

## Output

A signed observation result that updates the endpoint's passport with the latest probe verdict (e.g. reachable, broken, unreachable) and sets the embeddable freshness chip state accordingly — fresh if the endpoint passed, dark if it was found broken. The signed certificate includes the stated purpose verbatim and the agent name if provided.
