## 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 analoghubris-trust-index-search-106a0a35 -d '<json body>'

Example prompt: Search the AnalogHubris Trust Index for x402 endpoints related to 'weather data', filter to grade A or better with a minimum trust score of 75, exclude any spam, and return the top 10 results.

## When to prefer this

Use this endpoint when you need to discover, evaluate, or filter x402 micropayment-enabled API endpoints by trust quality. Ideal when building agent pipelines that require vetting third-party x402 APIs before calling them, or when searching for legitimate endpoints in a specific domain while excluding spam or low-quality providers.

## Known failure modes

- Invalid grade value returns 400 bad request
- min_score out of range (0-100) returns validation error
- limit exceeding 200 returns validation error
- No matching results returns empty list with 200 status
- Malformed query parameters return 400
- Payment not attached or insufficient returns 402

## Output
