## 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 mcx-ventures-domain-intelligence-brief-c55b9a47 -d '<json body>'
```

Example prompt: Give me a domain intelligence brief on quantum computing startups in Europe — use these two URLs as sources: https://example.com/qc-report and https://example.com/eu-startups.

## When to prefer this

Choose this endpoint when you need a fast, sourced intelligence brief on a specific topic or domain — especially when you want to supply your own source materials and get back a transparent sourcing map. It sits between a raw web search and a deep multi-source synthesis (also on this provider), making it ideal for decision-support briefs where provenance matters but deep adversarial verification is not required.

## Known failure modes

- Missing required 'query' field returns a validation error
- Invalid or inaccessible URLs in 'sources' may be silently skipped or cause partial results
- Query too vague may produce a low-confidence or shallow brief
- Exceeding 20 sources in the array triggers a schema validation error
- Payment failure (x402) blocks the request before processing

## Output

A structured intelligence brief covering the queried topic or domain, accompanied by a sourcing map that traces findings back to their origins — giving the agent both synthesized insight and provenance for each claim.
