## 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 rencom-x402-resource-search-b1d559ad
```

Example prompt: Search Rencom for x402 endpoints that can do image captioning — show me up to 5 results sorted by most popular so I can pick the best one.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover and select x402-compatible pay-per-call APIs at runtime, especially when optimizing for cost, reliability, or usage popularity. Prefer it over hardcoded endpoint lists when the best tool for a subtask is unknown or when cost/reliability tradeoffs need to be evaluated before committing to a call.

## Known failure modes

- Missing required 'q' parameter returns a 400 error
- Limit out of range (not 1-5) may return a validation error
- No matching x402 resources returns an empty results array
- Invalid sort_by enum value may return a 400 error
- Offset beyond available results returns empty results with has_more=false

## How this service works

Search for x402 resources. Ranks candidate endpoints by historical agent outcomes to minimize execution failure and cost variance before selection. Sort by price, popularity or reliability to ensure you get the best resources.

## Output

A paginated list of up to 5 matching x402 resource objects, each with a resource URL, human-readable description, price in USD, and blockchain network; plus pagination fields (limit, offset, has_more) and the sort method applied.
