## How to call it through Zero

```sh
zero fetch --capability mars-economic-micro-commercial-proof-ba270ff1
```

Example prompt: Can you look up commercial partner and supplier intelligence for 'industrial-grade water filtration systems' and give me the top ranked evidence plus a decision summary?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) snapshot of commercial partner or supplier intelligence with ranked evidence and decision support. It is ideal for quick due diligence, procurement research, or market viability checks where 3 ranked results with a compact summary are sufficient. Prefer it over full commercial intelligence endpoints when budget is constrained or a rapid micro-proof of commercial landscape is enough for the decision at hand.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Invalid or malformed query string may return empty or irrelevant results
- Payment failure via x402 protocol blocks access to results
- Rate limiting or quota exhaustion may result in HTTP 429
- Journey id mismatch may cause session continuity issues
