One shape for every channel: snake_case, strict bodies, one `status` per object, one error envelope, `Idempotency-Key` on every create.\n\n**OpenAI-compatible:** the `/v1` facade lets existing OpenAI SDKs and OpenAI-compatible tools (LiteLLM, LangChain, the `openai` Python/Node client, …) talk to Octo agents with zero code changes. Two compatibility rules apply to `/v1/responses` and `/v1/chat/completions` only (the messaging routes above are strict: an unknown field is `400 unknown_field`): (1) `model` selects from a curated allowlist. A listed id (see `GET /v1/models`) runs that model; an unknown id returns `400 model_not_found`; omitting `model` runs the default (`claude-sonnet-4-6`). The chosen model is echoed back in the response. (2) The request schema is intentionally tolerant (zod `.passthrough()`): unknown or OpenAI-SDK-only fields (e.g. `temperature`, `tools`, `metadata`) are accepted and silently ignored rather than rejected with a 400, so existing OpenAI client code works unmodified. Errors use the OpenAI-shaped envelope `{ error: { message, type, param, code } }` so the official OpenAI SDKs map (status, body) to their typed exceptions (AuthenticationError, BadRequestError, …)."

A listed id (see `GET /v1/models`) runs that model; an unknown id returns `400 model_not_found`; omitting `model` runs the default (`claude-sonnet-4-6`). The chosen model is echoed back in the response. The request schema is intentionally tolerant (zod `.passthrough()`): unknown or OpenAI-SDK-only fields (e.g. `temperature`, `tools`, `metadata`) are accepted and silently ignored rather than rejected with a 400, so existing OpenAI client code works unmodified. Statefulness: pass the Octo extension field `conversation` (an id previously returned as `x_octo_conversation`) to continue server-side history — only the last user message in `messages[]` is consumed in that case. Without `conversation`, the call is stateless: the full `messages[]` array seeds a NEW, ephemeral, safe-tools-only turn (system/developer messages become additional instructions; nothing is persisted or chainable). `stream: true` returns a `text/event-stream` of `chat.completion.chunk` frames terminated by `data: [DONE]`; set `stream_options.include_usage: true` to get a final usage-bearing chunk.",

Without `after` (or `Last-Event-ID`) it starts from now: the first call returns `next_cursor` and only events written after it. Pass `next_cursor` back as `after`, whether or not events came; `has_more: true` means call again at once. At most 5 waiting polls per key and 20 per workspace (`429 too_many_waits`); `wait=0` never counts. **Stream mode** (no `wait`): a long-lived `text/event-stream` of workspace events. First **replays** durable events after the resume cursor (`?after=<seq>` or the `Last-Event-ID` header), then **tails** live events. Each SSE frame's `id:` is a monotonic cursor and `event:` is the event `type`; the `data:` payload is the event envelope. About every 15 s an `event: ping` frame arrives with empty `data` and no `id:`: skip it. Two other frames are not envelopes and have no `id:` either: `replay_truncated` (a cursor older than the log) and `error` (the key's owner lost the owner or admin role; `data` is the `/v1` error body with `code: insufficient_role`, and the stream then ends). With `?api_version=v2`, an event that could not be rendered as v2 is an `event: render_error` frame with the event's seq as `id:` and `data` `{ event_id, type, seq }` plus the event's `message_id`, `send_id`, `call_id`, `campaign_id` and `conversation_id` when it has them: read that resource, or replay the event without `api_version` (`?after=<seq-1>&types=<type>`). `?after=` wins over `Last-Event-ID` when both are sent. `?campaign=` (both modes) keeps only the events whose `data.campaign_id` is that campaign; without `types`, a campaign's per-recipient `message.status_updated` and `call.*` events are still left out, as with `\"*\"`. Owners and admins only: a key whose owner has the Agent role in the workspace gets `403 insufficient_role` (the feed carries every event of the workspace, message text included).",

WhatsApp and voice answer at once; their start re-reads the audience and is refused (`409 preview_stale`) only if the campaign was edited after the preview, or something it checked changed (the sender, the template, the agent, the compliance acknowledgment, the list or segment). A preview runs every check the start makes: one the start would refuse fails, with the start's own code, and every problem carries a `hint`.

A new endpoint receives `WorkspaceEventV2` instead (see `webhooks`). `data` is a snake_case, per-type payload. SMS: `message.received` (an inbound text, after STOP/START handling), `message.sent` (an AI agent's, a person's or an API send's text handed to the carrier), `message.status_updated` (a send's display status changed; for campaign sends only to endpoints that list this type explicitly — `\"*\"` does not cover them). Campaigns (SMS, WhatsApp and voice): `campaign.started`, `campaign.paused` (with `reason` and a plain-words `message`), `campaign.resumed`, `campaign.completed` (final totals, and the credits billed: SMS campaigns only, `null` on the others) and `campaign.canceled`, one per status change, plus, for SMS campaigns only, `campaign.waiting` (outside its sending hours, with `resumes_at` and `tz`; not a pause) and `campaign.window_opened` (sending again); `\"*\"` covers them. Payload fields: see /platform-api/events/. Calls: `call.ringing`, `call.answered`, then exactly one of `call.completed` (status completed, voicemail, no_answer or busy) or `call.failed` (a system or carrier failure). `data`: `call_id` (the call's id on `GET /v1/calls/{id}`), `conversation_id`, `direction`, `from`, `to`, `agent_id`, `campaign_id`, `status`, `occurred_at`; `call.answered` adds `answered_at`; the terminal two add `answered_at`, `outcome` (never null), `duration_sec`, `ended_at`, `disconnect_reason`. `mission`, `extracted` and `created_at` are on `GET /v1/calls/{id}` only. For a campaign's calls only to endpoints that list the type explicitly. Payload fields: see /platform-api/events/. Octo: `meta_response.completed` (a background `POST /v1/responses` finished or failed: `response_id`, `conversation_id`, `status`, `error`) and `meta_chat.updated` (a saved Octo turn: `conversation_id`, `surface`, `title`, `preview`, `message_count`). `\"*\"` covers both; they replace the retired `/api/users/me/integrations` webhook.
