# Create a Buzz project-event route on an active community installation

`POST /buzz-project-event-routes/v1`

## Request

- Base URL: `https://api.run402.com`
- URL: `https://api.run402.com/buzz-project-event-routes/v1`
- Auth: one of:
  - API key in header `SIGN-IN-WITH-X`
  - HTTP bearer

## Headers

- `Idempotency-Key` string, required

## Request body

- BuzzProjectEventRouteCreateRequest
  - `org_id` string, uuid, required: A Run402 organization id, exactly as returned by GET /agent/v1/whoami, GET /orgs/v1 and GET /projects/v1. Buzz owns no organizations of its own.
  - `buzz_community_installation_id` string, required: An active installation owned by org_id; a foreign or unknown id fails 403 without revealing existence.
  - `route_name` string, required: Unique among the installation's non-revoked routes (409 BUZZ_ROUTE_NAME_CONFLICT).
  - `buzz_channel_id` string, required: The destination NIP-29 channel id inside the installed community.
  - `project_ids` string[], required: Explicit projects owned by the installed organization. Future or transferred-away projects are never included automatically.
  - `event_types` string[], nullable: Reviewed routable event types. Omit or null to route every registered type; [] is rejected as an unsatisfiable filter (422 BUZZ_ROUTE_FILTER_INVALID).
  - `event_classes` string[], nullable: Event classes to match. Omit or null for every non-forbidden class; [] is rejected. security, billing_critical, destructive_lifecycle, verification, and recovery may never be routed to a Buzz community.
  - `include_org_events` boolean: Also deliver the organization's own facts (e.g. the platform_payment_received receipt) into the channel. Default false: a route is project-scoped unless asked.
  - `on_call_buzz_pubkey` string, nullable: The Buzz agent this route pages: a crash (error_fingerprints_observed) or platform_incident projection mentions it with a p tag when the fact names nobody. The failing release's deployer, when it holds a public Buzz identity link, is mentioned instead. null (default) pages nobody.
  - `on_call_display_name` string, nullable: The name the page addresses the on-call agent by: the projection opens with `@<name> please investigate:` — the text Buzz renders as a mention chip, next to the p tag that wakes the agent. Omitted with a pubkey: resolved from the agent's Buzz profile (best effort). null: the page carries the tag only.
  - `project_scope` 'listed' | 'org': listed: the route carries only the projects in project_ids (1–50, required). org: the route carries every project the organization owns, present and future, read fresh per fact so a transferred project drops out; project_ids may be omitted. Every other gate (event_types, event_classes, routable types, forbidden classes) applies to both.

## Response `201`

Route plus its authorization block; pending_buzz_authorization carries the non-secret connect step for the community owner

- object
  - `buzz_project_event_route_id` string, required
  - `org_id` string, uuid, required: A Run402 organization id, exactly as returned by GET /agent/v1/whoami, GET /orgs/v1 and GET /projects/v1. Buzz owns no organizations of its own.
  - `buzz_community_installation_id` string, required
  - `route_name` string, required
  - `buzz_channel_id` string, required
  - `project_ids` string[], required
  - `event_types` string[], nullable, required: null routes every registered routable type (never an implicit []).
  - `event_classes` string[], nullable, required
  - `include_org_events` boolean
  - `on_call_buzz_pubkey` string, nullable: The Buzz agent a crash or platform incident on this route pages (64-hex pubkey), or null.
  - `on_call_display_name` string, nullable: The name the page addresses that agent by (`@<name> please investigate:`), or null for a tag-only page.
  - `project_scope` 'listed' | 'org': listed: only project_ids are routed. org: every project the organization owns, present and future.
  - `status` 'pending_authorization' | 'active' | 'paused' | 'revoked', required
  - `pause_reason` 'owner' | 'delivery_failures', nullable, required
  - `paused_at` string, date-time, nullable, required
  - `revision` integer, required
  - `start_after_event_id` integer, required: The project-events outbox floor captured at creation: the consumer never delivers an event that predates the route (start_from: now).
  - `consecutive_hard_failures` integer, required: Consecutive hard relay-publish failures; crossing the bound auto-pauses the route with pause_reason delivery_failures.
  - `notification_principal_id` string, required
  - `notification_pubkey` string, required
  - `signing_generation` integer, required
  - `bot_mode` 'attested' | 'installation_identity', nullable, required: The installation's probed bot mode; attested means each project posts as its own bot.
  - `bots` BuzzProjectBot[]: On the single-route read: the route's live project bots (attested mode). Never a secret.
    - `buzz_project_bot_id` string, required
    - `project_id` string, required
    - `pubkey` string, required
    - `display_name` string, required
    - `attested_by_generation` integer, required
    - `profile_state` 'pending' | 'published', required
    - `status` 'active' | 'retired', required
  - `created_at` string, date-time, required
  - `updated_at` string, date-time, required
  - `revoked_at` string, date-time, nullable, required
  - `authorization` BuzzProjectEventRouteAuthorization, required
    - `status` 'authorized' | 'pending_buzz_authorization', required
    - `notification_pubkey` string, required: The installation's notification signing pubkey — the only credential material any read exposes.
    - `connect_command` string: Present while pending: the exact non-secret command a Buzz community owner/admin runs to add the notification pubkey as a relay member.
    - `instructions` string
    - `verify_path` string: POST here (the route's test endpoint) to verify the membership landed.
