Pay for actual usage rather than an estimate

The estimate is held, never spent. The difference between the reservation and the settled figure returns to your balance the moment the run completes.

What you get

A gateway built with the clarity of a ledger

  1. wire

    Your OpenAI client, unchanged

    Chat completions and server-sent event streaming answer on the contract you already build against. Swap the base URL and the key; nothing else moves.

  2. catalog

    Claude, GPT, Gemini, Grok and Kimi

    One catalog, synced live, with every thinking and effort variant a model exposes and the rate attached to each.

  3. meter

    Cost recorded per request

    Input, output and cached tokens against the exact dollar figure, on every call, exportable as CSV whenever you want it.

  4. wallet

    Prepaid, in crypto

    Top up in USDT, BTC, ETH and more. Credit lands the moment the payment confirms on-chain. No subscription and no seat count.

  5. keys

    Keys encrypted at rest

    Issue and revoke as many as you need. A key is shown once at creation and stored only as a hash after that.

Trust, in plain language

Crypto is irreversible, so our controls are specific

Payment
Credit is added only after the invoice is confirmed.
Secrets
Customer keys are shown once, then stored only as hashes.
Recovery
Official support handles access and payment issues.

Change two lines and keep everything else

Point your existing integration at the gateway and keep the client, the SDK, and the request shapes you already wrote.
