Cannot be undone. ## OpenAPI ````yaml /api-reference/openapi.yaml delete /api/v1/voice_agents/{id} openapi: 3.1.0 info: title: Customer API version: 1.0.0-beta description: > **Beta.** This API is in beta. Contracts can still change while we complete it, including breaking changes; we announce changes in the release notes and keep them as rare as we can. Pin your integration to the field names and status codes documented here and treat unknown fields as optional. REST API to create and configure voice agents, add tools, test them with evals, read conversations, and place AI outbound calls. **Authentication.** Voice agents, settings, tools, evals and conversations use an API token created on the **Keys** page of your dashboard. Each operation lists the scope it needs under `x-required-scopes`; `:*` grants every action of a resource. Outbound calls use a separate outbound API token from the **Outbound Calls** page. Send either token as `Authorization: Bearer `. **Responses.** A single resource is returned as a flat JSON object; a collection is wrapped in a plural key (`voice_agents`, `tools`, `evals`, `conversations`) next to its paging fields. Deleting returns `204 No Content`. Everything is addressed by the voice agent's `id`; prompts and numbers are internal. **Errors.** Authentication failures return `{ "error", "message" }`. Request quotas return `429` with a `Retry-After` header and `{ "error", "message", "details" }`, where `error` is a stable machine-readable code. Every API call must finish within 30 seconds; longer requests return `503` with `mf-core:api-request-timeout`. Validation errors list the problems per field; the exact shape is shown on each operation. servers: - url: https://app.miyon.ai security: [] tags: - name: Voice Agents description: >- Create and manage voice agents. Configure them through the voice, prompt and knowledge-base settings endpoints. - name: Voice Agent Settings description: >- Read and change a voice agent's voice, prompt and knowledge-base settings. A voice agent has one prompt (its instructions, greeting and conversation settings). Read the schema of a settings group, then update one `key`/`value` pair per request. - name: Tools description: >- Create, configure, enable and execute agent tools. Tools are enabled per voice agent with `agent_id`. These endpoints accept scoped API tokens only; every error uses the `{ "error", "message", "details" }` envelope with a stable `mf-core:tool-*` code. - name: Outbound Calls description: >- Place AI calls and review their outcome. Authenticate with the outbound API token from the **Outbound Calls** page. - name: Conversations description: >- List and inspect the conversations of your account, including transcripts when your retention settings allow. - name: Evals description: >- Evals are automated test conversations that check how a voice agent responds. A scenario contains cases; each case contains the caller's turns and what the agent must say or do. Run a scenario to get pass/fail results. paths: /api/v1/voice_agents/{id}: parameters: - name: id in: path required: true schema: type: integer description: ID of the voice agent. delete: tags: - Voice Agents summary: Delete a voice agent description: >- Delete the agent together with its prompt and configuration.
