## 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 saylor-innovations-x402-market-intelligence-category-demand-vs-supply-1feb5c8d
```

Example prompt: Pull the latest x402 market intelligence report showing demand versus supply across API categories so I can see where there are gaps or oversupply in the ecosystem.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.005 USDC) snapshot of supply versus demand dynamics across the x402 API marketplace. It is ideal for builders evaluating where to launch a new monetized API, investors researching market gaps, or agents doing competitive landscape reconnaissance within the x402/micropayment ecosystem. Prefer this over general web search when you want structured, machine-readable category-level market data rather than anecdotal or editorial coverage.

## Known failure modes

- Stale data if the market intelligence snapshot hasn't been refreshed recently
- Empty or sparse category array if no data has been indexed yet
- 402 Payment Required if the 0.005 USDC micropayment is not included in the request
- Generic server errors (5xx) if the backend data pipeline is unavailable
- Rate limiting if too many calls are made in a short window
