Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-radar-service-search-c39c6e8f -d '<json body>'
```

Example prompt: Search the x402 Radar index for weather forecast APIs — I want to see the top results with their prices, payment addresses, and whether they're currently live.

## When to prefer this

Choose this endpoint when an AI agent needs to discover x402-compatible micropayment APIs by capability keyword, especially when you want merged coverage of both CDP Bazaar and PayAI indexes simultaneously with liveness and pricing data in a single call. Prefer this over browsing individual registries manually or calling the /stats endpoint when you need ranked, queryable results for a specific capability.

## Known failure modes

- Empty results if query keywords don't match any indexed service descriptions
- Stale liveness data if probes haven't run recently (liveness may show 'unprobed')
- Temporary Cloudflare tunnel unavailability causing connection errors
- Low relevance scores if query is too broad or too niche
- Payment failure (402) if $0.005 USDC not sent correctly with request

## How this service works

Search 26k+ x402 services (CDP Bazaar + PayAI merged index): q=keywords, returns ranked matches with price, network, payTo, liveness. By x402 Radar.

## Output

A ranked list of x402 service matches including each service's URL, payTo Ethereum address, source index (bazaar or payai), network (e.g. eip155:8453 for Base), liveness probe result (alive, x402-conformant, latency_ms), price in USD, relevance score, and description. Also includes total match count, returned count, and index update timestamp.
