Pricing

₹0.20 per audio-minute

That is the whole price list. Twenty paise for every minute of audio the engine produces, metered per audio-second, the same for:

• REST (POST /v1/tts) and WebSocket (WS /v1/tts/stream),
• every voice, including a voice we train for you,
• every format (wav, pcm16, opus).

Example	Audio	Cost
One OTP line (≈ 4 s)	4 s	₹0.013
A 30-second IVR message played 10 000 times	5 000 min	₹1 000
A voice agent talking 40 % of a 5-minute call, 1 000 calls a day for a month	60 000 min	₹12 000

How metering works

• The server records audio_s for every finished request in its request log; that log is what Usage and Billing in the portal show, and what the invoice is built from.
• Audio is counted as it is produced. Cancel a stream after 3 s and you pay for 3 s.
• Requests refused with 503, 4xx or that fail with 500 are not billed. /v1/normalize and /v1/voices are free.
• Months are calendar months in IST. Prices exclude GST.

How you pay

Usage is invoiced monthly in arrears by e-mail; no credits to pre-buy and no plans. For committed volume, SLAs or a dedicated node, talk to us.

Roadmap pricing

The engine gets cheaper as we keep squeezing audio out of each CPU core: the published plan is 20 paise today, 10 paise in about six months and under a paisa a minute within a year. Price changes are announced in the changelog and apply from the next calendar month; they only ever go down.
