## 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-opportunity-category-ranker-77d05bfb
```

Example prompt: Show me the top 10 ranked x402 product opportunity categories — I want to know which ones have strong demand, low competition, and favorable pricing so I can decide what to build next.

## When to prefer this

Use this endpoint when you need a ranked, multi-signal view of which x402 market categories present the best product opportunities — combining demand, competition, pricing, and concentration in one scored output. Prefer this over the demand radar or search endpoints when you want an actionable ranked list rather than a raw market map or search results.

## Known failure modes

- Invalid limit parameter (outside 1-25 range) returns validation error
- Unknown category value returns empty results or 400 error
- Payment not fulfilled (x402 payment required, 402 response if unpaid)
- Stale underlying data if x402scan or Bazaar aggregates are not fresh

## How this service works

## Output
