Per-minute cost depends on the selected providers.\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### Vapi API + MCP\n\n1. Read `subscriptionLimits.concurrencyBlocked` in the `POST /call` response, a full account queues the call rather than failing\n2. Confirm with a person before `vapi_create_call` or `vapi_buy_phone_number`, the server won't ask\n3. Pin transcriber, model and voice and set fallback plans so one provider outage doesn't drop calls\n4. Read the call log's cost breakdown to see what each provider charged\n5. Check `@vapi-ai/server-sdk` isn't pinned to 0.11.1, 0.11.2, 1.2.1 or 1.2.2\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, Vapi API + MCP or Vocily AI?\n\nVapi API + MCP scores 63.5 (B) on agent readiness against Vocily AI's 54 (C), and leads in 4 of 7 scored categories. Vocily AI leads on agent ergonomics and payments \u0026 pricing.\n\n### Do Vapi API + MCP and Vocily AI need an API key?\n\nBoth need an API key.\n\n### Can an agent call Vapi API + MCP and Vocily AI without installing anything?\n\nYes.
