Frequently asked questions.
How is call data secured when Custom API is in the loop?
Sempera runs on infrastructure certified to SOC 2 Type II. Call data is encrypted in transit and at rest. That certification covers the platform Sempera runs on rather than Sempera itself.
What does pricing look like for a Custom API-connected agent?
Per-minute and fully loaded. LLM, transcription, and TTS are included in the rate. Enterprise deals are contracted; talk to our team for a quote.
Do I bring my own Custom API credentials?
Yes. Built into Sempera. Sempera scopes the connection to what it needs to read and write and never stores account passwords.
Can I test before committing to production?
There is no self-serve sandbox. We set the agent up with you on the call and you hear it working before anything goes to production.
Who actually wires this up?
We scope the integration with you on the call and set it up for you. Most businesses are answering calls the same day.
