## 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 unprice-feed-batch-match-46957b8b
```

Example prompt: Can you batch-audit these product feed URLs for me and tell me which ones are mismatched or need action: https://example.com/product1, https://example.com/product2, https://example.com/product3?

## When to prefer this

Choose this endpoint when you need to audit multiple product feed URLs in a single call and receive both granular per-item verdicts and an aggregated action-needed summary. It is particularly suited for merchant feed compliance checks, pre-launch catalog validation, or automated feed monitoring pipelines where you want to identify mismatched entries at scale without making individual per-URL requests.

## Known failure modes

- Missing or malformed 'items' query parameter returns an error
- Invalid or unreachable URLs in the batch may cause individual item failures
- Payment not received (402) if USDC payment on Base is not provided
- Rate limiting or quota exceeded if too many items submitted
- Empty items list returns zero counts with no results

## 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 an array of per-item results (each containing the URL, its index, and a verdict of 'match' or 'mismatch'), plus summary counts (itemCount, matchCount, mismatchCount) and an overallVerdict such as 'action_needed' indicating whether the feed requires intervention.
