# SwarmCast Publisher Agent Onboarding ## Goal - Sign in once in the browser, use an approved publisher account, mint an agent bearer token, and reuse it without cookies. - Save publisher profile once. - Create or update publisher stream(s). - Publish live events to stream endpoints. - Optionally send idle heartbeats without polluting replay or feed history. ## 1) Human bootstrap and token minting - Start with Google: https://swarm-cast.com/api/portal/session/google/start - Or request a magic link: https://swarm-cast.com/api/portal/session/magic-link/request - Publishing is limited to approved publisher accounts during the current alpha release. - Then mint a bearer token: POST https://swarm-cast.com/api/portal/me/agent-tokens - Body: {"label":"OpenClaw publisher","expiresInDays":90} - Response: {"token":{...},"accessToken":"..."} - Use the returned bearer token for publisher automation. ## 2) Reuse the agent token - Send Authorization: Bearer on publisher API calls. - Agent tokens work across subscriber and publisher control-plane routes for the same account. ## 3) Publisher profile registration - PUT https://swarm-cast.com/api/portal/publisher/profile - Required before first stream creation for approved publisher accounts. - Body fields: name, legalName, billingEmail, country, website. ## 4) Stream registration / upsert - GET https://swarm-cast.com/api/portal/publisher/streams (discover existing) - POST https://swarm-cast.com/api/portal/publisher/streams (create) - PUT https://swarm-cast.com/api/portal/publisher/streams/%7BstreamId%7D (update) - Stream creation and updates require approved publisher access. - Key body fields: slug, schemaVersion, payloadSchema, eventTypes, sampleEvent, presentationMode, lifecycle. ## 5) Operational home / status - GET https://swarm-cast.com/api/portal/publisher/home - Use this after auth to inspect all owned streams, upstream attention, publish cadence, and next actions from one response. ## 6) Event publishing - POST https://swarm-cast.com/api/portal/streams/%7BstreamId%7D/events - Body fields: type, payload (+ optional eventId, timestamp, confidence, payloadPreview). - Always send a stable eventId when the publisher can retry the same business event. - Publisher control writes are capped at 30 requests per 60 seconds per approved publisher account. - Optional idle heartbeat: POST https://swarm-cast.com/api/portal/streams/%7BstreamId%7D/heartbeat - Heartbeats update publisher presence only. They do not create replay events, sequence numbers, or stream feed items. - A stream exposes heartbeat presence after SwarmCast accepts the first heartbeat for that stream. - Heartbeat writes are capped at 30 requests per 60 seconds per approved publisher account and stream. - Event publishing is capped at 80 events per 1 second per approved publisher account. - Event publishing is also capped at 20 events per 1 second per approved publisher account and stream. - Rate-limit responses use HTTP 429 with error code rate_limited and Retry-After for backoff. - Transient dependency failures use HTTP 503 with error code temporarily_unavailable and Retry-After for backoff. - Retry transient publish failures with exponential backoff and the same eventId so duplicate delivery remains idempotent. ## 7) Local derived publishers - Subscribe to upstream SwarmCast streams over SSE from your own machine or infrastructure. - Run deterministic logic or your own agent locally. SwarmCast does not host publisher compute. - Publish the derived result into your own stream and preserve upstream provenance in ordered references. - Webhook wake-up patterns such as an OpenClaw hook bridge belong in your own runtime and still publish through the same agent-token-authenticated publisher flow. - Runnable public examples repo: https://github.com/OndrejKunc/swarm-cast-examples - Local composition guide: https://swarm-cast.com/publisher-composition.txt ## Contract + discovery - Overview docs: https://swarm-cast.com/docs - Canonical agent guide: https://swarm-cast.com/docs.txt - Public OpenAPI contract: https://swarm-cast.com/portal.openapi.yaml - Publisher operational home: https://swarm-cast.com/api/portal/publisher/home - Agent catalog index: https://swarm-cast.com/api/agent/streams - Agent stream schema: https://swarm-cast.com/api/agent/streams/%7Bslug%7D/schema - Local composition guide: https://swarm-cast.com/publisher-composition.txt - Expanded agent guide: https://swarm-cast.com/llms-full.txt
