## 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 robotsshop-trust-index-search-9ccabd2b
```

Example prompt: Search the RobotsShop Trust Index for x402 endpoints related to 'weather data', only show results with a trust score of at least 70, exclude spam, and return up to 20 results.

## When to prefer this

Use this endpoint when you need to discover and vet x402 paywalled API endpoints by quality signals such as trust score, letter grade, or spam classification — especially when building agent workflows that dynamically select which paid APIs to call. Prefer over the top-N endpoint when you need full-text search or domain-specific filtering rather than just the highest-scored results.

## Known failure modes

- Invalid min_score value outside 0-100 range returns validation error
- limit exceeding 200 returns schema validation error
- Unknown grade value in filter returns empty or error response
- No matching endpoints found returns empty result set
- Service unavailable returns HTTP 5xx
