Four utilities. One integration.

Every service takes the same key, draws from the same balance, and answers in the same envelope. Add one without adding an integration.

Every major model, one balance.

One balance. Every service.

No per-service plans, no separate contracts, no second integration.

One balance, every service

OCR, speech, synthesis and chat all draw from the same credits. Spend them wherever the work is, in whatever mix. Nothing is ring-fenced to one service.

API keys you control

Issue scoped keys per service, set per-key rate limits, revoke instantly. Hashed at rest and shown once.

A playground for every service

Try OCR, speech and synthesis in the browser before you write a line of code.

Documented endpoints

A full OpenAPI spec covering every endpoint, envelope and error code.

Your data doesn't have to stay

Store nothing by default. Opt into a 24-hour cache, or point results at your own S3 bucket with encrypted credentials.

Lao, first-class

Lao and English throughout the product, and OCR tuned for Lao script on real, messy scans.

Pricing that scales with usage

Every plan includes a monthly credit grant, and one balance covers every service.
