Build anything. Your rules.
A full REST API for voice. Create agents, provision numbers, stream transcripts, receive webhooks. One key, one base URL, everything you need to ship.
Spin up an agent. One POST call.
Define the persona, language, voice and tools. The agent is live and reachable the moment the response comes back.
Every call, fully indexed.
Fetch any completed call by id. Duration, transcript, tools used, signed recording URL, all in one response.
Provision a number. Route it in seconds.
Buy local or toll-free numbers in 50+ countries, bind them to an agent, done. Porting available, no long forms.
Every call fires a signed event.
Point us at your URL, we push each event with an HMAC-SHA256 signature. Retries with exponential backoff, dead-letter queue included.
Turn-by-turn transcripts, streamed live.
Every word from both sides, timestamped and speaker-tagged. Push updates over websocket, or fetch the finalised transcript once the call ends.
Signed recording URLs, ready to play.
Every call auto-recorded to encrypted storage. Presigned links expire on your rules, stereo channels split by speaker, MP3 or WAV.
Structured data from unstructured calls.
Define the schema, we return typed fields with confidence scores. Intents, entities, outcomes, booking details, whatever you need to route the next step.
Tools, called mid-conversation.
Bind functions your agent can invoke live. Database lookups, CRM writes, warm transfers, calendar bookings, they run during the call, not after.
A call comes in. We POST to your server.
Every inbound call fires a request to your server_url with an HMAC-SHA256 signature. Verify it, discard anything that doesn't match.
Your server responds with the agent config.
Send back system_prompt, voice, tools, and any per-caller variables. Different config per number, per caller, per time of day, all your call.
Look up the caller. Personalise on the fly.
Query your database, check your CRM, hit a feature flag. Whatever your business needs, it happens in your code, in your infrastructure, before the agent even says hello.
Ship it back. The agent picks up.
You have < 5s to respond. Return 200 OK with the config, and the call connects. End to end, sub-second from the caller's first word.
Every call answered. Every time.
Zero hold time, zero missed calls. Tier-1 resolution on invoice, order, and account questions. Escalate to a human only when the caller actually needs one.
Books itself. Straight into your calendar.
The agent reads your live availability, offers real slots, confirms, and writes the booking back. Google, Outlook, or your own scheduler, whichever you're on.
Sort the maybes from the yeses.
The agent runs your BANT or MEDDIC framework in a real conversation. Scores the lead, routes hot ones to sales in real time. Cold ones get nurtured, not ignored.
No more press 1 for anything.
Callers say what they need, in their own words. The agent routes, resolves, or transfers. Skip the tree, skip the frustration, average handle time drops 40%.
