No OpenAPI document. **Vogent API.** IVR detection and navigation models for outbound calls. No public changelog and no release found since January 2026. ## Before you call either ### Bland AI API + MCP 1. Call `wait_for_call` (it waits up to 45 seconds) instead of polling `get_call_log` 2. Send destructive MCP tools a second time with the confirmation argument 3. Space calls to the same number at least 10 seconds apart or expect a 429 4. Budget $0.015 for every outbound attempt, including ones that never connect 5. Run `validate_pathway` before saving a pathway graph ### Vogent API 1. Send an `idempotencyKey` on `POST /dials`, a reused key returns 409 2. Create a call with `callAgentId`, plus `toNumber` and `fromNumberId` for phone calls 3. Tell the model when to emit `<|transfer|>`, since transfers fire on that tag 4. Verify webhooks with the HMAC in `X-Elto-Signature` 5. Expect new dials to fail at the workspace's concurrent dial limit until calls end ## Other comparisons with Bland AI API + MCP or Vogent API - [Bland AI API + MCP vs Bolna API + MCP](https://www.anchorterminal.com/compare/bland-ai-vs-bolna.md) - [Bland AI API + MCP vs Deepgram Voice Agent API](https://www.anchorterminal.com/compare/bland-ai-vs-deepgram-voice-agent.md) - [Bland AI API + MCP vs ElevenLabs Agents API + MCP](https://www.anchorterminal.com/compare/bland-ai-vs-elevenlabs-agents.md) - [Bland AI API + MCP vs Hume EVI (Empathic Voice Interface)](https://www.anchorterminal.com/compare/bland-ai-vs-hume-evi.md) - [Bland AI API + MCP vs Retell AI API + MCP](https://www.anchorterminal.com/compare/bland-ai-vs-retell-ai.md) - [Bland AI API + MCP vs Synthflow API + MCP](https://www.anchorterminal.com/compare/bland-ai-vs-synthflow.md) - [Bland AI API + MCP vs Ultravox Realtime API](https://www.anchorterminal.com/compare/bland-ai-vs-ultravox.md) - [Bland AI API + MCP vs Vapi API + MCP](https://www.anchorterminal.com/compare/bland-ai-vs-vapi.md) - [Bolna API + MCP vs Vogent API](https://www.anchorterminal.com/compare/bolna-vs-vogent.md) - [Deepgram Voice Agent API vs Vogent API](https://www.anchorterminal.com/compare/deepgram-voice-agent-vs-vogent.md) - [ElevenLabs Agents API + MCP vs Vogent API](https://www.anchorterminal.com/compare/elevenlabs-agents-vs-vogent.md) - [Hume EVI (Empathic Voice Interface) vs Vogent API](https://www.anchorterminal.com/compare/hume-evi-vs-vogent.md) - [Retell AI API + MCP vs Vogent API](https://www.anchorterminal.com/compare/retell-ai-vs-vogent.md) - [Synthflow API + MCP vs Vogent API](https://www.anchorterminal.com/compare/synthflow-vs-vogent.md) - [Ultravox Realtime API vs Vogent API](https://www.anchorterminal.com/compare/ultravox-vs-vogent.md) - [Vapi API + MCP vs Vogent API](https://www.anchorterminal.com/compare/vapi-vs-vogent.md)
