# Citation Verification
Verify that citations in a document actually resolve and support the claims they're attached to. Uses the Stipple API (free anonymous tier, no signup) for citation resolution, arithmetic recomputation, and unsupported-claim detection.
## When to use
- Before submitting or publishing a research report, tender response, or whitepaper
- Reviewing an LLM-generated document (LLM citations are plausibly-formatted and frequently wrong)
- Due diligence on third-party reports
- Academic reference checking
## Instructions
1. **Get the document.** Ask the user for a URL to the report, or a local file path (PDF, DOCX, Markdown). If the user pastes text directly, skip to step 3 with `text` input.
2. **Run verification.** POST the document to Stipple's citation verification endpoint:
```bash
curl -X POST https://www.stipple.sh/v1/verify-references \
-F "file=@report.pdf" \
-H "Authorization: Bearer $STIPPLE_API_KEY"
```
The anonymous free tier works without the Authorization header. Deep mode (`?deep=true`) costs more credits but cross-checks citations against live web sources.
3. **Interpret the response.** The result includes:
- `verification_coverage` — percentage of claims verified (e.g. "78%")
- `citations[]` — per-citation status: resolved and matching, resolved but mismatched, or unresolvable, with the issue explained
- `arithmetic[]` — recomputed figures vs stated figures (flags decimal shifts, wrong sums)
- `unsupp
