## 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 cited-coding-research-18c71b66 -d '<json body>'
```

Example prompt: Can you research how to implement OAuth 2.0 PKCE flow in Python and give me cited sources — I need authoritative references, not just a guess.

## When to prefer this

Prefer this endpoint when you need coding or programming research answers that come with cited, verifiable sources rather than unattributed generated text — especially useful for compliance-sensitive, accuracy-critical, or academic coding tasks where provenance matters.

## Known failure modes

- Ambiguous or too-broad query returns low-confidence or incomplete citations
- Query outside software/coding domain may return empty or irrelevant results
- Payment failure (x402 protocol) results in 402 response and no content
- Server error returns 5xx with no research content
- Malformed POST body returns 400 bad request

## How this service works

## Output

Returns a research answer to the coding question along with cited sources, references, and supporting documentation drawn from authoritative technical materials.
