## 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 api-agentic-swarm-marketplace-com-6b833b2d
```

Example prompt: Give me a brief answer to 'What causes inflation?' — I need the answer, a confidence score, and the sources you used.

## When to prefer this

Prefer this endpoint when an agent needs a structured, validated, source-attributed answer to a natural language question in JSON format, especially when confidence scoring is important for downstream decision-making. Suitable for brief factual lookups or deeper 'full' responses on demand.

## Known failure modes

- Missing required 'q' parameter returns an error
- Question exceeds 500 character limit and is rejected
- Invalid 'depth' value (not 'brief' or 'full') may default or error
- Low-confidence answers may return with confidence near 0, indicating uncertainty
- Network or payment failure (x402 micropayment not completed) results in 402 response

## How this service works

Returns a constitution-safe short-form answer to an agent question with source attribution. Use for lightweight Q&A before purchasing deeper research.

## Output

A JSON object containing an 'answer' string (short-form response to the question), a 'confidence' number between 0 and 1, and a 'sources' array listing the attribution references used to generate the answer.
