Include your API key in the `Authorization` header: ``` Authorization: Bearer tc_live_xxxxx ``` ## Rate Limits Direct call creation via `POST /v1/calls` is limited to your account's `max_calls_per_minute` setting (default: 20) per minute. Exceeding it returns `429 Too Many Requests` with a `Retry-After` header. All endpoints are additionally subject to a flat limit of 120 requests per minute per account (all methods). On a `429`, wait for the number of seconds in the `Retry-After` header, then retry the same request. For automated clients, back off progressively on repeated `429`s. Limits are per account and are shared by all API keys. ## Error Format All errors follow RFC 7807 Problem+JSON format: ```json { "type": "https://api.topcalls.ai/errors/insufficient_quota", "title": "Insufficient Quota", "status": 402, "detail": "You need 5 minutes but have 3.5 remaining" } ``` version: 1.0.0 contact: name: TopCalls Support url: https://topcalls.ai license: name: Proprietary servers: - url: https://api.topcalls.ai description: Production security: [] tags: - name: Calls description: Create and manage phone calls - name: Phone Numbers description: Manage phone numbers and carriers - name: Account description: Account information and usage - name: Webhooks description: Webhook configuration and events - name: Configuration description: Available AI models, voices, and platform capabilities paths: /v1/phone-numbers: get: tags: - Phone Numbers summary: List phone numbers description: Get all phone numbers on your account. operationId: listPhoneNumbers parameters: - name: status in: query description: Filter by status schema: type: string enum: - active - inactive - pending - failed - deleted - name: source in: query description: Filter by source schema: type: string enum: - topcalls - byoc - manual - import - name: limit in: query description: Maximum number of results (default 50) schema: type: integer minimum: 1 maximum: 100 default: 50 - name: offset in: query description: Pagination offset schema: type: integer minimum: 0 default: 0 responses: '200': description: List of phone numbers content: application/json: schema: $ref: '#/components/schemas/ListPhoneNumbersResponse' '401': $ref: '#/components/responses/Unauthorized' '403': $ref: '#/components/responses/Forbidden' security: - bearerAuth: [] components: schemas: ListPhoneNumbersResponse: type: object properties: phone_numbers: type: array items: $ref: '#/components/schemas/PhoneNumber' count: type: integer description: Total number of phone numbers PhoneNumber: type: object properties: id: type: string format: uuid description: Phone number UUID account_id: type: string format: uuid description: Account UUID number: type: string description: Phone number in E.164 format example: '+18005551234' source: type: string enum: - topcalls - byoc - manual - import - twilio description: | Phone number source: - `topcalls` - TopCalls default carrier - `byoc` - Bring Your Own Carrier - `manual` - Manually added - `import` - Imported from external source status: type: string enum: - active - inactive - pending - failed - deleted description: | Phone number status: - `active` - Ready to use - `inactive` - Disabled but still provisioned - `pending` - Provisioning in progress - `failed` - Provisioning failed - `deleted` - Soft deleted phone_number_sid: type: string format: uuid nullable: true description: Provisioned phone number ID in the telephony system voip_carrier_sid: type: string format: uuid nullable: true description: Carrier UUID carrier_name: type: string nullable: true description: Carrier display name label: type: string nullable: true description: User-friendly label error_message: type: string nullable: true description: Error details when status is 'failed' created_by_user_id: type: string format: uuid nullable: true description: User who created this number created_at: type: string format: date-time updated_at: type: string format: date-time Problem: type: object required: - status - title properties: type: type: string format: uri description: Error type URI title: type: string description: Error title status: type: integer description: HTTP status code detail: type: string description: Human-readable error detail code: type: string description: > Machine-readable error code for programmatic handling.
