The `url` is in this response only. It works once, for seven days. Same rules as giving a grant. Any caller; the scope needed is checked on what it acts on. ## OpenAPI ````yaml /openapi.json post /api/v1/invitations openapi: 3.1.0 info: title: artbucket version: '1' description: >- Agent-first asset management. The web UI is built on this API and nothing else, beside signing in at /api/auth. Send `Authorization: Bearer `: a key works in one workspace with one scope, and scopes are a ladder: read < propose < write < admin. People signed in to the app carry a session cookie instead, and their scope is what their grants add up to: on the organization, the workspace, or single collections and assets. A scope shown as needed on the workspace is also enough on the one collection or asset a route acts on. Agents (MCP at POST /api/v1/mcp) usually get `propose`: what they add waits for a human. servers: - url: http://localhost:3000 security: - bearer: [] - session: [] - {} paths: /api/v1/invitations: post: summary: Invite someone description: >- A grant waiting for whoever holds the link: they make an account or sign in, and have it.
