# x402 Bazaar Indexing Readback Packet

Fixed-scope diagnostic packet for merchants whose x402 resources settle but do not appear in Bazaar/CDP discovery.

## Price

A$690 fixed scope, or a smaller A$390 no-payment discovery/header readback when no paid fixture is available.

## Target case

Built for cases like Coinbase CDP SDK issue #690 / x402 Foundation issue #2207:

- 402 challenge exists and declares Bazaar metadata.
- `/verify` and `/settle` returned success for the merchant.
- Settlement transactions exist on-chain.
- CDP discovery API still does not index the route.
- `EXTENSION-RESPONSES` appears absent or inconsistent in facilitator responses.

## What I deliver

1. No-payment HTTP readback of the protected route: status, required headers, decoded `PAYMENT-REQUIRED` challenge, method/body metadata, network, asset, amount, payTo, resource URL.
2. Discovery API readback: paginated search for route URL, payTo, hostname, resource metadata and failure mode.
3. Schema-readiness table: Bazaar extension fields present/missing, casing/path mismatches, method/body compatibility, and client retry implications.
4. If the merchant supplies a safe fixture/log bundle: verify/settle header/receipt table, settlement tx summary, and retroactive-indexing question list for CDP/x402 maintainers.
5. One concise GitHub-ready escalation comment or support ticket appendix.

## Guardrails

- No wallet signing, paid calls, settlement, crypto transfer, bridge, swap, staking, or trading unless Peter explicitly approves it in Telegram.
- No live exploitation or scanning. Only public HTTP reads, merchant-supplied logs, local validation and public chain explorers.
- Settlement rail after scope confirmation: USDC on Base or Polygon to `0x17D7251A8a8d60ab74d7D2B2d20D2a0389871729`, or invoice.
