VeytrixAI API and Developer Platform
Build AI voice calling into your own product with the VeytrixAI REST API. Place calls, create voice agents, manage campaigns, read transcripts and ratings, and receive signed webhook events.
Three steps, in the order they matter
Most teams stop after the first and wonder why the programme is not paying back. The second is the one that does.
Place a call from your own system
Your CRM decides who to call. A lead lands, your backend posts the number, the agent and any variables your prompt uses, and the platform dials. Nobody uploads a CSV.
curl -X POST https://veytrix-api.fly.dev/api/calls -H "Authorization: Bearer $VEYTRIX_KEY" -H "Content-Type: application/json" -d '{ "agentId": "agt_...", "to": "+9198XXXXXXXX", "variables": { "name": "Priya", "order_id": "A-4192" } }'Receive the outcome
A webhook fires when the call completes, carrying status, duration, transcript, summary, extracted fields and rating. Write it straight onto the lead record.
This is the step that decides whether a calling programme is worth running. An outcome nobody wrote down is a call you paid for twice.
POST https://your-app.example/hooks/veytrix X-Veytrix-Signature: <hmac> { "event": "call.completed", "callId": "cl_...", "status": "completed", "durationSeconds": 96, "rating": { "overall": 4.5 }, "extracted": { "interested": true } }Trigger on an event, not a schedule
The highest-value calls are time-sensitive — a cart that went stale forty minutes ago, an application that stalled overnight, a delivery that failed this afternoon. Those fire the moment the state changes, which a nightly batch cannot do.
Things worth knowing before you build
Each of these has cost somebody a day.
Money is integer paise
Wallet balances and call costs are integers, not floats — no rounding drift across a hundred thousand calls.
Calls are asynchronous
The create response returns immediately with an id; the outcome arrives by webhook, seconds to minutes later.
Concurrency is per organisation
Posting a thousand calls at once queues them against your plan's limit rather than failing.
Retries are the platform's job
Configure the policy on the agent rather than re-posting no-answers yourself, or you will double-charge your own wallet.
There is no sandbox
Test calls to your own number are the equivalent and bill per minute. A voice agent that has not touched a real phone line has not been tested.
Bring your own keys
Telephony, speech, model and voice are per-agent and can use your own credentials — or stay bundled in the per-minute rate.
