## 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 neo-citation-check-f0a86e4e -d '<json body>'
```

Example prompt: Can you check these 3 citations from my article draft — make sure each quote actually appears word-for-word on its linked page and give me a signed report? Here are the pairs: quote 1 'Large language models are trained on massive datasets' from https://example.com/article1, quote 2 'Climate change is accelerating' from https://example.com/climate, quote 3 'GDP grew 3.2% last quarter' from https://example.com/econ.

## When to prefer this

Choose this endpoint when you need to verify multiple citations at once (up to 8) and require a signed, logged proof of the result — ideal for AI pipelines that generate referenced answers and need tamper-evident citation audits. Prefer over single-quote checkers (like neo verify-quote) when you have a full answer with several citations to batch-check in one call with one signed receipt.

## Known failure modes

- URL unreachable or returns non-200 — quote marked as not found / unreachable
- Quote not found verbatim — counted as failed, reflected in summary
- More than 8 citation pairs submitted — rejected with validation error
- Malformed URL in citation array — error or unreachable result for that entry
- Payment not completed — 402 response, report not generated

## How this service works

Check every citation in an answer (up to 8 quote+link pairs, or extracted from the text): which quotes are really on their pages. One signed, logged report.

## Output

A JSON object containing: 'checked' (number of citations verified), 'verbatim' (count found word-for-word), 'summary' (human-readable result like '3 of 5 quotes found word for word on their pages'), and 'signature' (a cryptographic signature proving the result is authentic and logged).
