Use the atlas
Open /atlas/ to browse the stamp player, switch specimen themes, play recordings, and share individual specimens. Static share pages live under /atlas/share/{id}/.
Use the data
Fetch /atlas/dawn-to-night.json for structured metadata. Fetch /llms-full.txt for agent context and /openapi.json for a typed description of the public static GET resources.
Source and rights
Source materials come from the National Park Service Yellowstone sound library. NPS labels these audio files as public domain, but downstream users should verify rights and third-party restrictions for their own use.
Limitations
YSL has no OAuth, MCP server, A2A endpoint, account dashboard, write API, payment flow, webhooks, or private data access. Agents should treat the project as a read-only public archive.
