# x402 Market Intelligence – Service Lookup by Name or Domain

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-market-intelligence-service-lookup-by-name-or-domain-8386f2cc
```

Example prompt: Look up the x402 service 'apollo' for me — I want to know its category, how many endpoints it has, what the lowest price is, whether it's active, and how many unique buyers it had in the last 30 days.

## When to prefer this

Use this endpoint when you know a specific x402 service name or domain and need to retrieve its marketplace profile — category, pricing, endpoint count, and buyer activity — rather than doing a broad topic search. Prefer this over the topic-search endpoint when the target service is already known. It is the right choice for vetting a vendor, checking current pricing, or confirming a service's active status before integration.

## Known failure modes

- No matches found if the name or domain fragment is too vague or misspelled
- Degraded response if the upstream Bazaar data source is partially unavailable
- Null fields for metrics if a service has no recent trading activity
- Wash flags present on volume/buyer data if traffic anomalies were detected
- Service may appear listed but with stale or null pricing if not recently indexed

## How this service works

Find an x402 service by name or domain: category, endpoints, lowest price, status and 30-day buyers.

## Output

Returns a structured match list where each entry includes the service host, name, category, number of endpoints, minimum price in USD, 30-day volume in USD, unique buyer count over 30 days, status, and any wash-trading flags. Also includes a summary, verdict, source URL, and data freshness timestamp.
