Product

One prepaid wallet. Two ways in.

Chat in the browser or build against the API — same balance, same models, same key. No provider SDKs, no provider keys.

For everyone

The chat app

A clean, fast chat UI for everyday use. Pick a model or let routing decide, and watch each reply’s cost land in your ledger.

For builders

The developer API

Call it with the tokenflow-sdk or straight over HTTP. One base URL, one auth header, every model behind it.

How it works

Three steps to billing by the token.

1/3

Top up your wallet

UPI or card, from ₹50. Prepaid, never expires.

2/3

Chat or build with one key

The browser app or your own code — same wallet either way.

3/3

Pay per token

Sub-cent precision, every charge logged.

Request path

Metering that never costs you latency.

Accounting runs async, after the stream
your app / chat
Sends a standard request with your TokenFlow key.
TokenFlow proxy
Auth, wallet check, model resolution, accounting.
resolved provider
Called under our keys. Tokens stream straight back.
Tokens stream straight back to you, unbuffered.
Smart routing

Send model="auto" and let it choose.

One classifier call routes each request to a model that fits — or pin any model yourself and routing steps aside.

Cheaper when it can be — a short classifier sizes the request, so simple prompts stop costing frontier prices.
Or pin it yourself — name a model and routing gets out of the way. Auto is a default, never a lock-in.
Failover before the first token — one cross-provider retry fires before anything streams, so you never see a half-answer.

A failed attempt is free. Cross-provider failover fires before the first token — and the ledger stays fully auditable.
