Unsigned webhooks and tool calls, IP allowlisting only.\n\n**GPT-Live.** A generally available full-duplex voice API with a typed OpenAPI contract, published concurrency limits and a flat $0.05 a minute for the voice session. Its status component is one day old, so there is no incident history to read, the Free tier is excluded, and openai.com refused our reader, so the terms and privacy policy were not read.\n\n## Before you call either\n\n### Bolna API + MCP\n\n1. Wait for the `completed` execution status, not `call-disconnected`, before reading cost, recording or extracted data\n2. Send `scheduled_at` with a numeric offset such as `+00:00`, since a `Z` suffix returns 500\n3. Back off exponentially on 429, the limit on `/call` is 500 requests a minute\n4. Reject webhook and tool requests that don't come from 13.203.39.153, 13.126.9.249 or 13.202.133.53\n5. Leave the MCP `api_key` argument empty unless acting as a sub-account, so the key stays out of the transcript\n\n### GPT-Live\n\n1. Create sessions on a server with the project API key. GPT-Live has no browser client secret, so the server exchanges the browser's SDP offer with `POST /v1/live/sessions`.\n2. Choose `delegation.type` at creation. Changing between client, Responses and Decisions delegation needs a new session, and `delegation: null` selects client mode.\n3. After `session.started`, listen for `error` with code `responses_validation_failed`. Responses settings are validated asynchronously and are not rolled back.\n4. Do not retry an outbound SIP `POST /v1/live/sessions` after a timeout. Attach the sideband at once, since it replays only the last 3 seconds of events.\n5. Keep the transport open until `session.closed` to read the final `usage.seconds`. A WebRTC session bills 15 seconds at creation, credited once it runs.\n\n## Questions\n\n### Which is better for AI agents, Bolna API + MCP or GPT-Live?\n\nGPT-Live scores 66.8 (B) on agent readiness against Bolna API + MCP's 52.6 (D), and leads in 6 of 7 scored categories. Bolna API + MCP leads on payments \u0026 pricing.\n\n### Do Bolna API + MCP and GPT-Live need an API key?\n\nBoth need an API key.\n\n### Can an agent call Bolna API + MCP and GPT-Live without installing anything?\n\nYes. Bolna API + MCP has a hosted endpoint at https://api.bolna.ai and GPT-Live at https://api.openai.com/v1/live/sessions.\n\n### Are Bolna API + MCP and GPT-Live open source?\n\nBolna API + MCP is open source (MIT).
