## 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 lodestar-index-batch-trust-lookup-6ab08dc2
```

Example prompt: Can you look up Lodestar Stamp trust receipts for these domains all at once: stripe.com, shopify.com, square.com, and paypal.com — and filter by the payments market?

## When to prefer this

Use this batch endpoint when you need to look up trust receipts for multiple businesses (up to 20) in a single call, rather than making separate individual reads per domain. It is cost-efficient and faster when evaluating shortlists, doing due diligence on multiple vendors, or comparing competitors within a specific market. Prefer the sibling single-domain endpoint if you only need to check one business.

## Known failure modes

- More than 20 domains provided — only up to 20 are accepted per call
- Invalid or malformed domain strings cause parsing errors
- No businesses found for provided domains returns empty result set
- Invalid market slug returns an error or empty market-filtered results
- Payment not processed or insufficient USDC balance blocks the call

## How this service works

Read your restaurant’s dated public receipt free. Watching delivers the baseline and published changes: first month free, then $149/month. On the record: verified against public sources and dated. We don't approve the booking. Payment never touches the record.

## Output

Returns Lodestar Stamp trust receipts for each business domain found in the index. One receipt read is billed per business found (not per domain queried). Each receipt contains trust signals and stamp data issued by the Lodestar Index for that business.
