Set stream to true for streamed chunks. Existing OpenAI SDK clients work by pointing the base URL at this API. ## OpenAPI ````yaml /openapi.yaml post /chat/completions openapi: 3.1.0 info: title: Flowyte V2 Control-Plane REST API version: 1.0.0 description: >- The single REST API for the Flowyte platform (base path `/api/v1`). Authenticate every request with a secret API key — `Authorization: Bearer flowyte_sk_…` — and each operation lists the scope the key must hold. Successful responses use the `ApiResponse` envelope; list responses use cursor-based `PaginatedResponse`. Errors are RFC 9457 problem+json. Streaming endpoints return Server-Sent Events (`event:\ndata:\n\n`, terminating with `event: done`). contact: name: Flowyte Platform license: name: Proprietary servers: - url: /api/v1 description: Flowyte control-plane (versioned URI; additive in v1). security: - apiKey: [] tags: - name: Agents description: The single user-facing entity. - name: Skills description: > Agent capabilities / tools. A skill is ONE atomic action — typically a single API call the agent makes in one step (look up an order, create a record, send a message, transfer the call). Use a skill when the task is a single step. When a task needs several details gathered across turns BEFORE acting, build a Playbook (which gathers the inputs and then calls skills) — see the Playbooks tag. - name: Integrations description: Native OAuth integrations. - name: Knowledge description: RAG knowledge sources & preview. - name: Playbooks description: > Multi-turn conversation scripts — a node graph (gather → confirm → branch) the agent follows to collect several inputs IN ORDER across turns before acting. Build a playbook when a single skill call isn't enough because the agent must gather MANY details first, or run a SEQUENCE of skills, before it can finish (e.g. take a full service request: gather the problem, address, and time, confirm, THEN file it; qualify a lead; a multi-step intake). A playbook does NOT call an integration itself — it owns the conversation and holds the state across turns; the actual action is performed by the SKILL(s) it gathers the inputs for. So a playbook ORCHESTRATES skills. Rule of thumb — one API call → a Skill; "gather N things in order, then submit" → a Playbook that drives the conversation and calls the skill(s) at the end. - name: Variables description: > The agent-wide interaction-variable registry (B.4b) — DERIVED at read time from the agent's playbooks and skills (collect slots, skill output bindings, {var} placeholders) and merged with a thin annotation overlay (notes, declared type hints, manual declarations). Read-only observation, NEVER a gate: it never validates a reference and never affects authoring, publish, or runtime behaviour. - name: Guardrails description: Deterministic guardrail policies & caller verification. - name: Numbers description: Phone numbers / DIDs. - name: Test description: Test, simulate, talk-token, probe. - name: Observe description: Post-call analytics, conversations, receipts, transcripts. - name: Billing description: Plans, wallet, usage, fixed phrases. - name: Voices description: Voice catalog. - name: Webhooks description: Webhook endpoints & deliveries. - name: AuditLogs description: API/key activity logs. - name: Chat description: Chat channel — sessions, messages, OpenAI-compatible, widget. - name: PublishableKeys description: Browser-safe, one-agent publishable keys. - name: Widget description: Embed widget config + snippet. - name: Uploads description: Multipart file uploads backing file_id params - name: Meta description: Platform metadata (language/SKU/tier capabilities). paths: /chat/completions: post: tags: - Chat summary: OpenAI-compatible chat completions description: >- An OpenAI-compatible chat completions endpoint where the model field is your agent ID.
