Passes through named bus events with a : ping heartbeat every 15 s. The full event catalog flows: graph.updated and the import.* / identity.* families in-process, and worker-origin events (job.completed, insight.proposed, contradiction.detected, belief.superseded, basin.shifted, brain.trained) via the database bridge. Subject-scoped events reach only the subject’s own stream; org-readable events reach every member’s stream. A per-organization cap of 5 concurrent streams applies: the sixth returns 429 too_many_streams with Retry-After. Last-Event-ID is accepted for compatibility with resuming clients but is not replayed in v1.

Authorization

This route requires the read scope. A missing or invalid credential returns 401 authentication_error. A valid credential without the scope returns 403 permission_denied, and the problem body names the exact scope required.

Headers

These are request conventions the contract does not declare as parameters, so they do not appear in the schema tables below.

Header	Applies	What it does
`X-Exo-API-Key`	Required	Your Exo API key, `exo_<env>_<token>`. `Authorization: Bearer exo_...` is accepted as an alternate.
`X-Exo-Subject`	Ignored	This resource is organization-level, so the header is accepted and has no effect.
`Idempotency-Key`	Not applicable	The replay engine covers POST requests only.
`X-Request-Id`	Response	Returned on every response, including `204`s. Quote it in a support request.

Success responses

Status	Meaning
`200`	Successful Response

Errors

Status	Code	When
`400`	`invalid_request`	Malformed request, for example an invalid cursor.
`401`	`authentication_error`	Missing or invalid credentials.
`403`	`permission_denied`	Missing scope, or an unprovisioned subject selector.
`404`	`not_found`	The resource does not exist, or is not visible to this caller.
`409`	`conflict`	A conflict with the current state of the resource.
`422`	`validation_error`	The request was understood but failed field validation.
`429`	`rate_limit_exceeded`	Rate limit exceeded. Retry after the Retry-After interval.
`503`	`service_degraded`	A dependency is temporarily unavailable. Safe to retry.

Beyond the shared statuses, this route can answer with too_many_streams. Every problem body names its own code, and the type URI always resolves to the matching page. Every error is an RFC 9457 application/problem+json body carrying a stable code, a requestId, and a suggestedAction where Exo has one. See Errors.

Notes

Five concurrent streams per organization. The sixth is 429 too_many_streams with Retry-After.
v1 does not replay. Last-Event-ID is accepted so resuming clients do not error, and it is ignored. A client that must not miss a transition should use a webhook.
Reach differs by event. Events about the organization reach every member. Events about a person reach that person only. See Events.
