## 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 vextorium-x402-bazaar-service-search-0e74f6b5 -d '<json body>'
```

Example prompt: Search the x402 Bazaar for weather services — show me the top 5 results ranked by usage, including their prices and which networks they support.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover x402-compatible paid APIs at runtime by capability keyword, rather than hardcoding a specific service URL. Ideal for agent orchestration systems that need to find the best available micropayment API for a given task based on real usage data and price. Prefer over manual browsing or static registries when freshness and usage ranking matter.

## Known failure modes

- Empty query string returns no results or validation error
- Very niche keywords may return zero matching services
- Limit set too low may truncate relevant results
- Service catalog may have stale entries if recently delisted
- Non-English keywords may return fewer matches if catalog is English-indexed
