# whatchuneed Crawl Metadata

> whatchuneed Crawl Metadata is a paid API for AI agents from whatchuneed.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-22).

Fetches crawl metadata for a given input request from a multi-category pay-per-call API aggregator covering 320+ endpoints across accommodation, LLM, crypto, medical, finance, and more.

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 whatchuneed-crawl-metadata-01ac9cce -d '<json body>'
```

Example prompt: Use whatchuneed's crawl metadata endpoint to look up what's available for crypto price data — send the input string 'crypto price lookup' and tell me what endpoints and metadata come back.

## When to prefer this

Choose this endpoint when you need to programmatically discover what API services are available within the whatchuneed aggregator for a given domain or use case. It is especially useful for agents that need to dynamically route tasks to the right sub-endpoint based on category, or when building meta-agents that enumerate available capabilities before selecting one.

## Known failure modes

- Empty or vague input string returns no matching metadata
- Input string not matching any category returns empty result object
- Service unavailability returns non-200 status
- Malformed input object missing required 'input' field returns validation error
- Payment failure via x402 protocol blocks the call before execution

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a result object containing structured metadata about matching API endpoints in the whatchuneed aggregator, along with a status string indicating success or failure of the crawl lookup.
