{"service":"Fresh CC0 Feed","description":"A freshness feed of works just dedicated to the public domain (CC0 / Unlicense), cleaned into one schema with reproducible provenance. For AI agents/shops that need modern, rights-clean assets they can use or train on — and disclosure-ready proof. You pay for freshness, aggregation, and verified CC0 — not the bytes (the bytes are free).","paid_endpoints":{"/v1/recent":{"method":"GET","params":"type(image|audio|dataset|code), source(github|zenodo|freesound), limit","price_usd":"0.02","payment":"x402 (USDC on Base)"},"/v1/item":{"method":"GET","params":"id=github:owner/repo, zenodo:<recordId>, or freesound:<soundId>","price_usd":"0.02","note":"full provenance incl. verbatim LICENSE SHA-256 (github)"}},"free_endpoints":["/","/health","/llms.txt","/sample","/.well-known/x402"],"accepted_licenses":["CC0-1.0","Unlicense"],"sources":["github","zenodo","freesound"],"schema_version":"1.0","schema":{"item_id":"stable id, e.g. github:owner/repo","type":"image | audio | dataset | code","title":"work title","creator":"uploader/author handle","source":"where it was aggregated from (v1: github)","source_page_url":"canonical page where the license is stated","asset_url":"link to the work (we link, we don't re-host)","declared_date":"when the creator dedicated/created it (repo creation)","first_seen_by_us":"when our feed first saw it","license":"CC0-1.0 | Unlicense (public-domain dedications only)","license_url":"canonical license deed URL","license_evidence":"reproducible proof: detected SPDX, and on /v1/item a verbatim LICENSE-file SHA-256","confidence":"high = explicit PD dedication (only 'high' is served)","residual_rights_flags":"non-copyright risks that can survive CC0 (e.g. trademark, publicity)"},"disclaimer":"Provenance is the dedication evidence we found with citations, NOT legal advice or a guarantee.
