# x402 Radar Service Search

> x402 Radar Service Search is a paid API for AI agents from con-suggests-dubai-lie.trycloudflare.com, paid per call via x402, $0.005/call, status down (last checked 2026-10-21).

Searches a merged index of 26,000+ x402 micropayment services (CDP Bazaar + PayAI) by keyword, returning ranked matches with price, network, payTo address, and liveness status.

## Facts

- Endpoint: POST https://con-suggests-dubai-lie.trycloudflare.com/api/search?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: down
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-radar-service-search-c28c5f24
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_2iUxJyzelu_QEMzMrtpw-

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-c28c5f24 -d '<json body>'
```

Example prompt: Search the x402 Radar index for services related to 'weather forecast' and show me the top results with their prices, networks, and whether they're currently live.

## When to prefer this

Use this endpoint when you need to discover x402-compatible micropayment APIs across both the CDP Bazaar and PayAI ecosystems in a single search. It is the best choice when an agent needs to self-equip with new tools, when you want to compare prices and liveness across providers, or when you need to find services payable on-chain with USDC. Prefer this over manual browsing of individual registries or calling the snapshot endpoint (which only returns aggregate stats, not searchable results).

## Known failure modes

- Empty results if keywords don't match any indexed services
- Stale liveness data if probes haven't run recently (liveness field may be 'unprobed')
- Trycloudflare tunnel may be temporarily unavailable (ephemeral hostname)
- Payment failure if the $0.005 USDC x402 handshake is not completed correctly
- Rate limiting or rejection if the endpoint is overloaded

## 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

Returns a ranked list of matching x402 services, each including: service URL, payTo wallet address, source registry (bazaar or payai), network identifier (e.g. eip155:8453), price in USD, relevance score, a human-readable description, and liveness probe results (whether the endpoint is alive, x402-conformant, and its latency in ms). Also returns total match count and index update timestamp.
