## How to call it through Zero

```sh
zero fetch --capability unprice-merchant-feed-audit-2593132c
```

Example prompt: Can you audit my Google Merchant feed at https://example.com/google-merchant-feed.xml and tell me if any of the product URLs have mismatches or issues — check up to 10 items?

## When to prefer this

Choose this endpoint when you need a quick, per-request audit of a Google Merchant Center product feed to detect URL mismatches without setting up your own parsing infrastructure. It is especially useful for agents managing e-commerce clients, running pre-campaign checks, or monitoring feed health on a pay-per-use basis via USDC micropayments rather than a subscription.

## Known failure modes

- Feed URL is inaccessible or returns non-XML — endpoint may return an error or empty results
- Feed contains no parseable items — itemCount and parsedItemCount return 0
- Network timeout if feed XML is very large
- Invalid or malformed feed URL parameter — may return a validation error
- Limit parameter out of range — may default or error

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

Returns a JSON object with the audited feed URL, an array of per-product results (each with URL, index, and match/mismatch verdict), total item count, parsed item count, mismatch count, and an overall verdict (e.g. 'action_needed' or 'ok') summarizing feed health.
