No concurrent-session limit is published, the status page has no Voice Agent component, and phone calls are inbound only through a Twilio trunk the customer owns.\n\n**ElevenLabs Agents API + MCP.** API keys scoped to endpoint groups, with per-key credit limits and service accounts. $0.08 a minute excludes LLM tokens and carrier minutes.\n\n## Before you call either\n\n### AssemblyAI Voice Agent API\n\n1. Send `session.end` before closing the socket. Without it the session stays resumable, and billed, for 30 seconds\n2. Retry only `at_capacity`, `concurrency_exceeded` and `internal_error`, with backoff. Every other session error code is fatal\n3. Send `tool.result` inside the `reply.done` handler, not straight after `tool.call`\n4. Mint a one-time token with `GET /v1/token` for browser clients and never ship the API key to a page\n5. Deduplicate webhooks on `event_id`, and verify `X-AAI-Signature` against the raw body bytes because a 401 is not retried\n\n### ElevenLabs Agents API + MCP\n\n1. Create a key scoped to the agents endpoints with a credit limit before handing it to an agent\n2. Back off exponentially on `rate_limit_exceeded`, and wait for calls to finish on `concurrent_limit_exceeded`\n3. Use signed URLs or conversation tokens for private agents instead of exposing the API key\n4. Set `platform_settings.privacy.retention_days` where you don't need 2 years of history\n5. Pick a low-latency LLM, the pipeline waits on it every turn\n\n## Questions\n\n### Which is better for AI agents, AssemblyAI Voice Agent API or ElevenLabs Agents API + MCP?\n\nElevenLabs Agents API + MCP scores 71.3 (BB) on agent readiness against AssemblyAI Voice Agent API's 64.4 (B), and leads in 5 of 7 scored categories. AssemblyAI Voice Agent API leads on payments \u0026 pricing.\n\n### Which is cheaper for voice agents, AssemblyAI Voice Agent API or ElevenLabs Agents API + MCP?\n\nThey cost about the same, $0.075 per minute of call for AssemblyAI Voice Agent API and $0.08 per minute of call for ElevenLabs Agents API + MCP. These are the vendors' published prices for the job.\n\n### Do AssemblyAI Voice Agent API and ElevenLabs Agents API + MCP need an API key?\n\nAssemblyAI Voice Agent API needs an API key. ElevenLabs Agents API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call AssemblyAI Voice Agent API and ElevenLabs Agents API + MCP without installing anything?\n\nYes. AssemblyAI Voice Agent API has a hosted endpoint at wss://agents.assemblyai.com/v1/ws and ElevenLabs Agents API + MCP at https://api.elevenlabs.io/v1/convai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/assemblyai-voice-agent-vs-elevenlabs-agents.json, and with the fewest tokens: https://www.anchorterminal.com/compare/assemblyai-voice-agent-vs-elevenlabs-agents.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"assemblyai-voice-agent\", \"b\": \"elevenlabs-agents\"}`.
