## 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-map-cross-source-category-seller-intelligence-49992817 -d '<json body>'
```

Example prompt: Give me a cross-source market map of x402 paid APIs — show me how revenue, call volume, and payer concentration are distributed across categories, which sellers dominate, how well each category is covered in the registry, and where the schema-quality gaps are.

## When to prefer this

Choose this endpoint when you need a holistic, cross-source view of the x402 paid API ecosystem — especially for competitive analysis, identifying underserved categories, evaluating seller concentration, or finding metadata/schema gaps. Prefer this over single-source directory lookups or seller-specific scoring endpoints when you want market-level intelligence rather than route-level detail.

## Known failure modes

- Payment not included or insufficient (0.25 USDC on Base required via x402 protocol)
- Invalid or malformed POST body returns 400 error
- Service temporarily unavailable returns 503
- Stale data if underlying registry sources have not been recently crawled
- Empty results if no x402 data has been indexed yet
