Personal scope shows only calls you own or participated in, with direction relative to you. Workspace scope requires workspace owner/admin access. Usage is returned in minutes and credits. Requires a user-owned credential with loop:read. ## OpenAPI ````yaml /api-reference/openapi.json get /loop/calls openapi: 3.1.0 info: title: Famulor API version: 1.0.0 description: >- REST API for Famulor. Authenticate with an API key (`fam_...`, created under **Settings → API Keys**) or an OAuth 2.0 access token (`fam_at_...`) as a Bearer token. Every response uses a consistent envelope: `{ "data": ... , "meta": { ... } }` on success and `{ "error": { "code", "message" } }` on failure. List endpoints paginate with `?limit=` (default 50, max 200) and `?offset=`; `meta.pagination.total` carries the total match count. REST operations require API Access through the workspace plan or a recurring add-on. Without it, regular operations return `403 api_access_required`. The invoice-payment and billing-portal operations remain available with a valid `billing:write` credential after a failed plan payment so an authorized owner, admin, or billing member can recover billing. The same customer-facing capabilities are available as MCP tools at `https://app.famulor.io/mcp` (Model Context Protocol, streamable HTTP) using the same credentials, scopes, and workspace access. MCP availability is controlled separately by Connect AI / MCP, not by API Access. servers: - url: https://app.famulor.io/api/v1 description: Hosted platform. - url: https://{domain}/api/v1 description: White-label tenant domain — same paths, tenant branding. variables: domain: default: app.famulor.io description: Your white-label tenant domain. security: - bearerAuth: [] tags: - name: Account description: Self-inspection of the calling credential. - name: Migrations description: Preview and import data from supported legacy platforms. - name: Assistants description: Create and manage voice assistants. - name: Tools description: >- Reusable tools (HTTP APIs and external MCP servers) assistants can call mid-conversation. - name: Voices description: Browse the text-to-speech voice library. - name: Calls description: Start outbound calls and read call history, transcripts and recordings. - name: History description: Unified conversation history across calls, messaging and assistant emails. - name: Campaigns description: Outbound calling campaigns with a compliant power dialer. - name: Leads description: Manage Audience contacts across campaigns, channels and Call QA metrics. - name: Segments description: >- Saved, dynamic lead filters — reusable audience definitions used for Audience search and campaign lead assignment. - name: Suppression description: Cross-channel marketing opt-outs and active workspace suppression records. - name: Callbacks description: >- Scheduled callbacks booked by the Schedule callback tool across voice, chat, and email. - name: Phone Numbers description: Marketplace numbers and customer-provided numbers. - name: Famulor Loop description: >- Personal business-phone access, directory, presence, devices, and Loop call recents. - name: SIP Trunks description: Bring your own SIP provider and numbers. - name: Carrier Connections description: Connect a supported carrier account and import its existing phone numbers. - name: Knowledge Bases description: RAG knowledge bases and documents for assistants. - name: Settings description: Workspace-level settings such as caller-memory defaults. - name: Billing description: Balance and minutes ledger of the key owner. - name: Automations description: >- Native workspace automations — list, create, update, trigger.

REST operations also require API Access for the credential's workspace. Keys can be restricted to scopes such as `assistants:read`, `calls:write`, `campaigns:write`, `automations:read`, `dashboards:read`, `dashboards:write`, `leads:write`, `segments:write`, `loop:read`, `loop:write`, `phone_numbers:write`, `sip_trunks:write`, `knowledge:write`, `voices:read`, `billing:read`, `billing:write`, `settings:write`, `platform:read`, `platform:write`; a `*:write` scope implies the matching `*:read`. Automation and dashboard endpoints also accept the legacy `calls:*` scope. Keys without scope restrictions have full access within the workspace's available capabilities. ````
