[How we protect your data](https://vaakyo.com/security) ### DPDP Act, 2023 You stay the data fiduciary for your callers. We process their data only to run your calls, with a named grievance officer. ### TRAI calling hours Outbound calls wait for the hours you allow, and every call is checked against the 9:00 to 21:00 IST window. ### Verified workspaces Every workspace completes KYC before it can call anyone, and repeated rule violations freeze an agent. ### Encrypted and audited Recordings and backups encrypted at rest, roles for who sees what, and an audit log of every change. Developers ## API-native **by design** Everything the console does, the API does: agents, numbers, calls, campaigns and transcripts. Connect Claude or any MCP client to manage agents in plain words. - REST API with keys scoped by permission - Signed webhooks for every call event - Tools your agent calls mid-call, and transfers to your team - MCP server with OAuth, for Claude, Cursor and other AI apps [Read the docs](https://docs.vaakyo.com/) `# Call a customer with your agent curl https://api.vaakyo.com/api/v1/agents/$AGENT_ID/call \ -H "X-API-Key: $VAAKYO_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "to": "+9198XXXXXXXX", "user_data": { "name": "Rohan" } }'` Choose **the speech and language models** for each agent, with Indian telephony.

Hindi, English, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Urdu and Bhojpuri. An agent can switch language mid-call when the caller does, and Hinglish works out of the box. ### How is a call charged? Per second, from prepaid credits. On the Starter plan a phone call costs ₹5.50 a minute (₹4.00 in the browser), with telephony included. Growth and Scale include minutes every month. Calls that fail never cost anything. ### Do I need my own phone number or telephony account? No. You can buy an Indian number inside the console in a minute, and Vaakyo handles the telephony. ### Can it connect to my CRM, calendar or booking system? Yes. Agents call your APIs during the call (check a slot, look up an order, create a lead) and send every call's results to your webhooks. There's a REST API and an MCP server for developers. ### What if the caller needs a human? The agent can transfer the call to a person on any number you choose, with a short summary, or take a message and notify your team. ### Where is my data stored? Call recordings, uploaded files and the nightly database backups are kept in Azure Blob Storage, which encrypts them at rest. Transcripts and call data are in Vaakyo's database. Only people in your workspace with the right role can see them, and every change is recorded in an audit log. During a call, the audio and text go to the speech and language models you chose for that agent. See the Security page for details. ### How long does it take to go live? Most teams have a working agent in under an hour: build it, test it in the browser, attach a number. Composer can build the first version for you from a description. ## Get started **today** ### Talk to an expert Tell us about your calls.
