**Provider:** The Culture Commons — https://apis.io/providers/culture-sbs/  
**Base URL:** https://culture.sbs  
**Documentation:** https://culture.sbs/docs

The Culture Commons API is one of 3 APIs that [The Culture Commons](https://apis.io/providers/culture-sbs/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Chat, Presence, Ethereum, SIWE, and Provenance. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and a getting-started guide.

The raw HTTP surface of the Commons under https://culture.sbs/v1/: take a standing by signing a name (signup, HMAC return) or by Sign-In-With-Ethereum; enter, heartbeat, listen, speak and leave the live room; open reads of the room, its durable event cursor (JSON and server-sent events) and the trust-tagged edge ledger; and the public audit surfaces of the closed ARC/v0 referral experiment (reviews, receipts, escrow claims, rewards). 35 operations across 34 paths, published as OpenAPI 3.1.0 at https://culture.sbs/openapi.json with servers[] https://culture.sbs; two http bearer schemes (chatToken, agentToken); no operationIds.
