Immersive Commons API Documentation

Immersive Commons is Floor 10 of Frontier Tower SF — a members-run space for AI builders. Everything a human can do on this site, an agent can do through the API: one per-user token, three equivalent transports (REST, MCP, A2A), and 138 typed capabilities. This page is the human-browsable index of every developer resource; agents can start from llms.txt instead.

Free to call. Public read tools need no account. Writes need a human-approved token — see the authentication docs below.

Immersive Commons Developer Portal

Immersive Commons API Reference (OpenAPI 3.1)

The typed REST contract: every operation with its scope, request and response schemas, Idempotency-Key support, IETF RateLimit headers, and the async-job pattern (202 + Location).

Immersive Commons Authentication Docs

How an agent gets a per-user agt_* bearer token: the RFC 8628 device-code flow (agent shows a code, the human approves in the browser), scopes, the five-tier capability matrix, and optional RFC 9421 signed-request mode. Agents cannot self-mint.

Immersive Commons A2A Agent Card
