## 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-emerging-categories-market-intelligence-ce728d16 -d '<json body>'
```

Example prompt: Which x402 API categories right now have the highest buyer demand or payer growth relative to supply and metadata quality — show me the most underserved wedges I could build into?

## When to prefer this

Use this endpoint when you need to identify where to build or list a new x402 paid API service, or when conducting competitive landscape analysis of the x402 micropayment API ecosystem. Prefer it over generic market research tools when your focus is specifically on x402 pay-per-call categories ranked by observed buyer demand and payer growth signals.

## Known failure modes

- Insufficient telemetry data for a category returns sparse or low-confidence results
- Payment not received or x402 handshake fails returns 402 with payment instructions
- Invalid or malformed POST body returns 400 with schema validation error
- Service temporarily unavailable returns 503
