# Fresh CC0 Feed

> A pay-per-call feed of works freshly dedicated to the public domain (CC0 / Unlicense), aggregated into one clean schema with reproducible provenance, settled in USDC over x402 on Base. Agents pay for freshness + verified-CC0 + provenance, not for the bytes (the bytes are free). NOT expired-copyright works — modern works whose creators chose to give them away.

For agents: GET /v1/recent returns the newest verified CC0/Unlicense items (params: type, sort=created|updated, limit). GET /v1/item?id=github:owner/repo returns one item with full provenance, including a verbatim LICENSE-file SHA-256 you can reproduce. Only explicit public-domain dedications are served (confidence "high"); "free to use" custom licenses are excluded. Provenance is evidence with citations, not legal advice. Inspect /sample free first. Price: $0.02 USDC per paid call.

## Endpoints

## Schema (schema_version 1.0)
item_id, type, title, creator, source, source_page_url, asset_url, tags, declared_date, first_seen_by_us, license, license_url, license_evidence, confidence, residual_rights_flags.

## Notes
- Sources: GitHub (code/assets), Zenodo (datasets/software/media), Freesound (audio).
- Provenance is the dedication evidence we found with citations, NOT legal advice or a guarantee. CC0 waives copyright only — trademark, patent, and personality/publicity rights can survive. Public-domain treatment varies by jurisdiction. Verify before relying on any item.
