No phone numbers or SIP, so you bridge Twilio or another carrier yourself.\n\n**Vocily AI.** The REST API is documented in detail for a product a few months old, with an OpenAPI 3.1 file, required idempotency keys on calls, a Retry-After header on 429 and signed webhooks. No status page, SLA, SDK or security programme was found, and two releases in September 2026 removed fields under `/v1` on the day they were announced.\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### Vocily AI\n\n1. Send a fresh UUID in `Idempotency-Key` on every `POST /v1/calls`. The API refuses the request without it\n2. Pass a `from_number` the workspace holds. The shared Test Number returns 403 from the API\n3. Publish a version and make it live before placing a call, or the call returns 409 `agent_not_published`\n4. Branch on `detail.code`, falling back to the top-level `code`. A 429 body is flat, so read `Retry-After`\n5. Read `currency` on every call and chat record. Costs are in rupees or dollars depending on the organisation\n\n## Questions\n\n### Which is better for AI agents, Deepgram Voice Agent API or Vocily AI?\n\nDeepgram Voice Agent API scores 68.1 (B) on agent readiness against Vocily AI's 53.8 (D), and leads in 4 of 7 scored categories. Vocily AI leads on agent ergonomics.\n\n### Do Deepgram Voice Agent API and Vocily AI need an API key?\n\nBoth need an API key.\n\n### Can an agent call Deepgram Voice Agent API and Vocily AI without installing anything?\n\nYes.
