Every endpoint is scoped to one organization. Authenticate with a bearer token and, if your token can reach more than one organization, name the one you mean with the `X-Anyreach-Org` header. See [Authentication](https://docs.anyreach.ai/api-reference/authentication). This reference is generated from the running service, so the request and response shapes here are the ones the API actually enforces. servers: - url: https://api.anyreach.ai description: Production security: - bearerAuth: [] tags: - name: Agents description: >- Create and configure the agent that handles a conversation, and manage its versions. An agent's behaviour lives in a version; publishing a version is what puts it on the air. - name: Conversations description: >- Create, list, retrieve, and message conversations between your users and Anyreach agents. - name: Conversation attachments description: >- Upload files into a conversation and read them back. Uploads are two-step: presign, PUT to the returned URL, then mark the attachment complete. - name: Conversation events description: >- The ordered event stream behind a conversation — turns, tool calls, transfers, and status changes. - name: Knowledge bases description: >- A knowledge base (a `dataset` in the API) is a collection of embedded content an agent can retrieve from. - name: Knowledge base sources description: Attach and detach sources to a knowledge base. - name: Sources description: >- A source is a file or URL whose content is ingested, chunked, and embedded. - name: Phone numbers description: >- Buy, list, and release phone numbers, and point each one at the agent that should answer it. - name: Trunks description: >- SIP trunks for bringing your own carrier. A trunk carries calls between your carrier and Anyreach. - name: Inbound routing description: >- Rules that decide which agent answers an inbound call, evaluated before the call connects. - name: Agent assist description: >- Look up the live-assist context for a number so a human agent can see what the AI agent knows. - name: Human handoff description: >- Connections to the help desk a conversation escalates into, and the test endpoint that proves one works. - name: Email domains description: >- Register a sending domain and verify its DNS before an agent can send from it. - name: Email addresses description: >- The addresses on a verified domain, and the agent that handles mail arriving at each one. - name: Unsubscribes description: >- The suppression list. An address on this list is never emailed again until it is removed. - name: Web widgets description: >- The embeddable chat and voice widget: its appearance, its allowed domains, and the agent behind it. - name: Campaigns description: >- An outbound campaign dials a contact list with a given agent on a given schedule. Start, pause, and close control its lifecycle. - name: Campaign contacts description: >- The people a campaign dials. Contacts can be added while the campaign is running. - name: Campaign configurations description: >- Reusable dialing settings — calling windows, retry policy, timezone handling — that campaigns reference. - name: Campaign stats description: >- Per-campaign outcome counters, and the organization-wide cap on how many calls run at once. - name: Custom data description: >- Your own tables, queryable by an agent mid-conversation. Define a table, load rows, and expose read-only stored queries as agent tools. - name: Metrics description: >- The definitions an LLM judge scores a conversation against. Lint and preview a metric before you run it at scale. - name: Evaluations description: A scorecard binding a set of metrics to a population of conversations. - name: Evaluation runs description: >- One execution of an evaluation over a conversation set, and the results it produced. - name: Workflows description: >- Automations built from steps. A workflow is edited as a version and goes live when a version is published and set live. - name: Workflow triggers description: >- What starts a workflow — a schedule, a webhook, or a point in an agent conversation. Triggers are versioned alongside the workflow. - name: Workflow executions description: >- Run a workflow and read back what happened. Executions are synchronous by default; use the async endpoint for long-running work. - name: Workflow credentials description: >- Secrets a workflow step authenticates with. Values are write-only — they can be set and rotated, never read back. paths: /core/trunks: get: tags: - Trunks summary: List Trunks description: List all trunks. operationId: listTrunks parameters: - name: name in: query required: false schema: anyOf: - type: string - type: 'null' title: Name - name: created_after in: query required: false schema: anyOf: - type: string format: date-time - type: 'null' title: Created After - name: created_before in: query required: false schema: anyOf: - type: string format: date-time - type: 'null' title: Created Before - name: updated_after in: query required: false schema: anyOf: - type: string format: date-time - type: 'null' title: Updated After - name: updated_before in: query required: false schema: anyOf: - type: string format: date-time - type: 'null' title: Updated Before - name: limit in: query required: false schema: anyOf: - type: integer - type: 'null' title: Limit - name: cursor in: query required: false schema: anyOf: - type: string - type: 'null' title: Cursor - name: x-anyreach-org in: header required: false schema: anyOf: - type: string - type: 'null' description: Organization ID for user PATs (pat_ prefix tokens) title: X-Anyreach-Org description: Organization ID for user PATs (pat_ prefix tokens) responses: '200': description: Successful Response content: application/json: schema: type: array items: $ref: '#/components/schemas/Trunk' title: Response List Trunks Core Trunks Get example: - id: 3fa85f64-5717-4562-b3fc-2c963f66afa6 organization_id: 3fa85f64-5717-4562-b3fc-2c963f66afa6 name: Example created_at: '2026-01-15T09:30:00Z' updated_at: '2026-01-15T09:30:00Z' created_by: user:3fa85f64-5717-4562-b3fc-2c963f66afa6 modified_by: user:3fa85f64-5717-4562-b3fc-2c963f66afa6 inbound_config: id: null enable_noise_cancellation: false media_encryption: null allowed_addresses: null caller_id_header: null header_metadata_mappings: null outbound_config: id: 3fa85f64-5717-4562-b3fc-2c963f66afa6 address: string auth_username: string auth_password: string transport: null media_encryption: null managed_account_id: 3fa85f64-5717-4562-b3fc-2c963f66afa6 external_id: 3fa85f64-5717-4562-b3fc-2c963f66afa6 '422': description: Validation Error content: application/json: schema: $ref: '#/components/schemas/HTTPValidationError' security: - HTTPBearer: [] components: schemas: Trunk: properties: id: type: string title: Id organization_id: type: string title: Organization Id name: type: string title: Name created_at: type: string format: date-time title: Created At updated_at: type: string format: date-time title: Updated At created_by: anyOf: - type: string - type: 'null' title: Created By modified_by: anyOf: - type: string - type: 'null' title: Modified By inbound_config: anyOf: - $ref: '#/components/schemas/InboundTrunkConfig' - type: 'null' outbound_config: anyOf: - $ref: '#/components/schemas/OutboundTrunkConfig' - type: 'null' managed_account_id: anyOf: - type: string - type: 'null' title: Managed Account Id external_id: type: string title: External Id type: object required: - id - organization_id - name - created_at - updated_at - external_id title: Trunk description: Trunk entity representing a SIP trunk configuration.
