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/campaigns/{campaign_id}/stats: get: tags: - Campaigns summary: Get campaign statistics description: | Returns call counters for the campaign, computed from call records at request time, plus the current (most recently created) run, if one exists. `stats` is all zero when the campaign has no calls yet. `current_run` is `null` when the campaign has never been started. operationId: getCampaignStats parameters: - name: campaign_id in: path required: true description: Campaign UUID schema: type: string format: uuid responses: '200': description: Campaign statistics content: application/json: schema: $ref: '#/components/schemas/CampaignStatsResponse' '401': $ref: '#/components/responses/Unauthorized' '403': $ref: '#/components/responses/Forbidden' '404': description: Campaign not found content: application/problem+json: schema: $ref: '#/components/schemas/Problem' security: - bearerAuth: [] components: schemas: CampaignStatsResponse: type: object description: >- Call counters for a campaign, computed from call records at request time, plus its most recent run. required: - campaign_id - stats - current_run properties: campaign_id: type: string format: uuid stats: type: object description: >- Computed live from the campaign's call records on every request; not a cached snapshot. required: - contacted_count - completed_count - success_count - failure_count - total_duration_seconds - updated_at properties: contacted_count: type: integer description: Number of calls that reached a contacted state. completed_count: type: integer description: Number of calls that completed. success_count: type: integer description: >- Number of calls whose disposition matches one of the campaign's configured conversion outcomes. failure_count: type: integer description: Number of calls that ended in a failed status. total_duration_seconds: type: integer description: Cumulative talk time across all calls, in seconds. updated_at: type: string format: date-time description: Timestamp when these counters were computed for this response. current_run: type: object nullable: true allOf: - $ref: '#/components/schemas/CampaignRun' description: >- The most recently created run for this campaign, or null if the campaign has never been started.
