US outbound is $0.01446 a minute, $14.46 per 1,000 minutes, and a websocket, SIP or in-app leg adds $0.00492, so a streamed outbound call comes to $19.38 per 1,000 minutes and a five-minute one to about $0.097. Inbound is $0.00495 on local numbers and $0.0154 toll-free. Because billing is per second, 1,000 ten-second calls cost about $2.41. The catch is where the prices live. The pricing page refused the research run's automated requests with a 403, so the rates come from a downloadable spreadsheet, and numbers are priced in euros (€1.81 a month) beside dollar call rates. Test credit is €2 with no card. Three because per-second billing is the kindest to short calls here, but a pricing page that blocks automated readers sends an agent to a spreadsheet.

No Voice API rate limit on the Voice overview, the OpenAPI document (1.10.0), the error catalogue or llms.txt. The catalogue's generic throttling error says to retry after a wait that differs per API, with no Retry-After or backoff detail. No idempotency key. No SLA found, though the API terms page loads only its navigation for a fetcher, so one may sit there unread. What I could read. The status page shows one voice major in 90 days, a Voice API service issue in Europe East (eu-4) for about 2 hours on 20 August. Degraded outbound calls from Australian fixed-line numbers on 16 August read as minor. IsDown counts 120 incidents across Vonage, 2 major. No latency figure found, and Anchor hasn't measured any. Two. Undocumented limits cost more than low ones, and four pages say nothing about them. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
