| What matters | APIFleet | Deepgram Voice Agent API |
|---|---|---|
| Starting point | $0.03 per connected AI minute Platform fee, billed per second | $0.075 / min Standard pay-as-you-go Voice Agent |
| Payment model | Prepaid usage. $10 minimum top-up. No monthly subscription or free credits. | Voice Agent pricing changes with the selected tier and provider ownership. |
| Cost scope | AI providers and carrier charges are additional. Customer-owned keys are paid directly to providers. | Standard is $0.075 per minute. Custom BYO LLM and TTS is listed at $0.05 per minute; those external providers have their own bills. |
| Working style | Configurable assistants, tools, knowledge, browser tests, simulations and call logs. | A realtime conversation API for applications integrating speech and agent behavior. |
Compare the whole agent API, not a transcription rate.
Deepgram’s transcription service and Voice Agent API solve different parts of a voice stack. When evaluating the complete agent API, identify the components included in the chosen tier and the application code you will maintain around it. A BYO rate moves some charges to other providers.
When Deepgram Voice Agent API may fit
Evaluate Deepgram when you want a managed voice API inside an application you control. Test your intended configuration rather than assuming all pricing tiers behave identically.
When APIFleet may fit
Evaluate APIFleet when you also want a workspace for assistants, tools, knowledge, browser tests, simulations and call logs.
APIFleet currently limits new workspace access. Existing users can sign in; contact us about a new project. Carrier accounts, standalone previews, file transcription and simulation caller/judge models require customer-owned credentials.
Two workloads to price explicitly
These hypothetical examples assume exactly 1,000 or 10,000 connected AI minutes. They calculate APIFleet’s platform portion only; model, speech, carrier, numbers and any other service charges must be added.
| Workload | APIFleet platform arithmetic | Deepgram Voice Agent API estimate |
|---|---|---|
| Pilot: 1,000 minutes | 1,000 × $0.03 = $30.00 | Apply the vendor’s published or quoted terms to the same provider stack and duration. |
| Operation: 10,000 minutes | 10,000 × $0.03 = $300.00 | Include subscriptions, allowances, overages, rounding and implementation work when applicable. |
A bundled vendor rate cannot be compared directly to the APIFleet platform portion. We do not infer Deepgram Voice Agent API’s concurrency or seat limits from a minute rate; confirm them for your planned workload.
Run a one-assistant switching pilot
Before switching from Deepgram Voice Agent API, recreate one assistant, replay its tool requests, test interruptions and transfers, then move one controlled route with a written rollback. Use the voice-agent migration checklist and conversation test plan with the vendor-specific checks below.
What to test before switching
- Identify whether you need transcription or the complete Voice Agent API.
- Add direct provider costs when choosing a BYO configuration.
- Budget for the application and management interface around the API.
There is no universal one-click import. Map prompts, tools, credentials and routing explicitly, then run controlled calls. Our gradual migration guide gives you a sequence with a rollback boundary.
