## 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 tradepilotusa-document-compare-03c6fbe9 -d '<json body>'
```

Example prompt: Compare these two consultation scheduling documents for me and highlight what changed — specifically look for differences in scheduling availability and who confirms appointments, and flag anything that seems missing or inconsistent. The audience is our operations manager.

## When to prefer this

Choose this endpoint when you need a structured, auditable side-by-side comparison of two text documents with explicit tracking of differences, consistencies, omissions, and evidence gaps — especially when requires_human_review flagging is important. Prefer this over generic LLM document diffing when you need provenance metadata, assumption tracking, and a clean JSON artifact suitable for downstream workflows or compliance records.

## Known failure modes

- source_text below 20 characters or missing — validation error
- brief below 10 characters or missing — validation error
- source_text exceeds 32000 characters — request rejected
- brief exceeds 12000 characters — request rejected
- Only one document provided instead of two — incomplete comparison or error
- Malformed JSON input — 400 bad request
- Payment not included or insufficient — 402 payment required

## How this service works

Compare the supplied documents for substantive changes, omissions, conflicts, and questions; do not give legal advice. Uses buyer-supplied information only; no external research or outbound actions. Returns a draft for human review.

## Output

Returns a JSON object containing: a plain-language summary of key differences, a detailed markdown artifact breaking down substantive changes, consistencies, and omissions; a list of assumptions made during comparison; identified evidence gaps; a requires_human_review flag; provenance metadata including timestamp and whether external research was performed; and a request_id.
