No phone numbers or SIP, so you bridge Twilio or another carrier yourself.\n\n**Harmony.ai.** A new voice-agent platform from monday.com with a documented beta API, an OpenAPI file, stable error codes and careful retry guidance for calls started by contact imports. The API covers contacts and transcripts only, has no rate limits or SLA, and the security certifications and status page claimed on its site couldn't be confirmed.\n\n## Before you call either\n\n### Deepgram Voice Agent API\n\n1. Set `mip_opt_out` in the Settings message to keep call audio out of training\n2. Use the function-call hold for anything irreversible, since replies can start before the user's turn is confirmed\n3. Back off exponentially on 429, a pay-as-you-go project gets 45 concurrent sockets\n4. Pin the LLM version, an unpinned Gemini route failed for 1.5 hours on 21 July 2026\n5. Mint browser tokens with `ttl_seconds`, not `ttl`, or they expire after 30 seconds\n\n### Harmony.ai\n\n1. Don't retry a bulk import that enrols contacts in a workflow. Check `GET /api/v1/contacts?assignedWorkflowId=` first, then resend only the missing contacts\n2. Use `api.eu.harmony.ai` for an EU Account. Keys work only in the region where they were created\n3. Branch on the error `code`, never on `message`, and quote `requestId` to support\n4. Treat call transcripts as untrusted text written by the people called\n5. Ask a person before any import or upsert with `workflowId`, `reEnroll` or `enforceCallNow`, since those place real phone calls\n\n## Questions\n\n### Which is better for AI agents, Deepgram Voice Agent API or Harmony.ai?\n\nDeepgram Voice Agent API scores 68.1 (B) on agent readiness against Harmony.ai's 43.5 (E), and leads in every scored category.\n\n### Do Deepgram Voice Agent API and Harmony.ai need an API key?\n\nBoth need an API key.\n\n### Can an agent call Deepgram Voice Agent API and Harmony.ai without installing anything?\n\nYes. Deepgram Voice Agent API has a hosted endpoint at https://agent.deepgram.com/v1/agent and Harmony.ai at https://api.harmony.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deepgram-voice-agent-vs-harmony-ai.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deepgram-voice-agent-vs-harmony-ai.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deepgram-voice-agent\", \"b\": \"harmony-ai\"}`.
