Evidence claims:
- [sourced_fact] README: API free for any purpose; assets are CC0 and never require attribution, but building on the live API requires a small 'Powered by Poly Haven' credit; points to ToS.md. · locator: README intro · source: https://github.com/Poly-Haven/Public-API
- [sourced_fact] ToS.md: API free for commercial and non-commercial use; calls must carry a unique Referer or user-agent matching the software name; attribution clause applies only to live API use, not downloaded CC0 assets; Poly Haven may change or terminate the API without notice; governed by South African law. · locator: ToS sections 2, 4, 7 · source: https://github.com/Poly-Haven/Public-API/blob/master/ToS.md
- [sourced_fact] Repo metadata: AGPL-3.0, not archived, last push 2026-10-04. · locator: GitHub API fields license, archived, pushed_at · source: https://api.github.com/repos/Poly-Haven/Public-API
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- code: license=AGPL-3.0 hosting=permitted redistribution=restricted modification=restricted training=unknown · AGPL-3.0 code license (network copyleft). · evidence: https://github.com/Poly-Haven/Public-API
- other: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · Hosted API access (api.polyhaven.com) is governed by ToS.md as a separate agreement from CC0 assets and AGPL code; ToS does not address model training in the lines read. · evidence: https://github.com/Poly-Haven/Public-API/blob/master/ToS.md
