Wallet in, tokens out / inference at pressure

Open the valve.
Pay for what flows.

Penstock streams inference from six frontier models while your wallet pays per token actually delivered, priced about five percent under market, with no signup, no API key, and no prepaid balance.

Three turns of the wheel

From wallet to stream

01

Open a tab

Point any crypto wallet at Penstock and open a running balance. Funds stay in your custody until tokens arrive. There is no account to create and nothing to preload.

02

Send one POST

A single endpoint serves every model. Standard chat format, streaming responses, payment attached per request.

curl -X POST https://api.dexter.cash/api/x402/inference \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kimi-k3",
    "messages": [
      {"role": "user", "content": "Draft the outflow schedule."}
    ]
  }'
03

Close when you like

Your tab settles against tokens delivered, nothing more. Close it and every unspent unit stays in your wallet. There is nothing to withdraw because it never left.

Priced downstream

Every response is billed against what actually arrived at your client. A token that never streams is a token you never pay for. Close the tab mid-generation and the ledger stops where the stream stopped.

Our rates sit roughly five percent under the going market price for each model, rechecked continuously. When upstream costs fall, the price you see falls with them. There are no tiers, no seats, and no minimum commitment. One stream, one rate, one wallet.

Money you do not spend never leaves your wallet. That is the whole trick: the tab is a channel, not a vault.
