Designed to make every conversation feel natural. Pollax's voice AI lets agents follow rapid shifts in conversation, sentiment, pitch, and tone — so they match the mood of every interaction across 23 languages.
Tailored to match your unique brand
Adapted to a variety of accents and languages
Industry-leading voice response time
Native pronunciation and scripts — with the ability to switch language mid-call based on the speaker.
Every request uses a Bearer API key (sk_live_… or sk_test_… for the sandbox). Keys are scoped per tenant, so each account only sees its own agents and calls.
Official TypeScript and Python SDKs — npm i pollax and pip install pollax. Both wrap agents, calls, campaigns, and webhook signature verification.
Subscribe a webhook URL. Pollax POSTs signed events (call.initiated → answered → completed/failed) with transcripts, recordings, and outcomes. Verify the signature with the SDK helper.
Yes. Use a sk_test_ key for the sandbox — calls are simulated with magic numbers driving the outcome, and the same webhooks fire so you can build end-to-end before going live.
Grab an API key, install the SDK, and place a call in minutes.
