## 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 x402-bazaar-resource-change-history-a469f682
```

Example prompt: Pull the full change history for x402 Bazaar resource ID 1 — I want to see every price change, payto address change, schema change, and any delisting events with their SHA-256 snapshots so I can verify the payment terms before paying.

## When to prefer this

Use this endpoint when you need to audit or verify the historical payment terms of a specific x402 Bazaar resource before making a payment — particularly to detect if price or payto address has changed, or to confirm no tampering has occurred. Prefer this over the trust dossier or attestation endpoints when you specifically need the full chronological event log rather than a summary score or signed proof.

## Known failure modes

- Invalid or non-existent resource ID returns an error or empty result
- Payment of $0.01 USDC not included or rejected results in 402 Payment Required
- Resource has no change history if monitoring just began (empty event list)
- Network timeout if the backend is unavailable

## How this service works

Full change history for one x402 Bazaar resource: every snapshot (SHA-256 audit trail) and every change event (price_changed / payto_changed / schema_changed / delisted) since monitoring began. Use it to verify an endpoint's payment terms before paying. Find ids for free: https://5.75.142.199.sslip.io/x402/resources
