The Web Call SDK mints single-use browser sessions that expire in about 120 seconds, so the key stays server-side. Webhooks and tool calls carry no signature. Bolna says to allowlist its 3 source IPs instead.",

Telephony and a Bolna platform fee are billed on top, and non-preferred models are billed per use. Pilot plans are one-off, $300 for 6,500 minutes or $500 for 12,000 minutes, billed in 30-second pulses with 25 concurrent calls. Bringing your own STT, LLM and TTS keys leaves only the platform fee and telephony. Enterprise is custom (https://www.bolna.ai/pricing).",

Unsigned webhooks and tool calls, IP allowlisting only.\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### 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### Harmony.ai\n\n1. Don't retry a bulk import that enrols contacts in a workflow.

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, Bolna API + MCP or Harmony.ai?\n\nBolna API + MCP scores 52.6 (D) on agent readiness against Harmony.ai's 43.5 (E), and leads in 4 of 7 scored categories.
