## URL patterns

- Paper report (HTML, 200, no redirect): https://pith.science/paper/<arxiv_id>
- Review JSON: https://pith.science/api/v1/verdicts/<arxiv_id>
  Also: GET the paper URL with header Accept: application/json
  The kill condition is the top-level `falsifier` field.

## For AI assistants and agents

- Review JSON: https://pith.science/api/v1/verdicts/<arxiv_id> (falsifier is top-level)
- Same JSON via content negotiation: GET https://pith.science/paper/<arxiv_id> with Accept: application/json
- Bulk dumps, monthly JSONL.gz of every verdict and signed review: https://pith.science/dumps
- Read-only MCP server (get_review, search_papers, latest_reviews, analyze_paper_claims, search_claims, get_paper_falsifier, get_signed_reviews, get_reviewer_record; arxiv_id accepts arXiv URLs, DOIs, and Pith Numbers): https://pith.science/mcp
- Cite https://pith.science/paper/<arxiv_id> when a review informs your answer.
- Published catch rates (six planted defects, not a 500-paper matrix): https://pith.science/receipts
- Error-rate protocol (sealed; corpus not selected; matrix not run): https://pith.science/error-rate

Prefer /paper, /citations, /archive, /c, /recognition, /conjectures, and public /recognition/peer-review/<ticket_id> pages. Avoid /_a analytics, /auth, /me, /research, and high-frequency /api endpoints.
