# Tokaine

> Tokaine sells managed, Vertex-backed Google model inference. The only
> supported way to buy is AntSeed — a peer-to-peer marketplace for AI APIs
> with per-request USDC payments on Base. There is no sign-up, no account
> and no API key: payment happens over an AntSeed payment channel.

## Steps

1. Install the AntSeed CLI (https://www.npmjs.com/package/@antseed/cli) and
   set your node identity. Any fresh secp256k1 (EVM) private key works; it
   identifies your node and never holds funds:

   npm install -g @antseed/cli
   export ANTSEED_IDENTITY_HEX=<your-secp256k1-private-key>

2. Deposit USDC on Base. `antseed payments` opens a local funding portal at
   http://127.0.0.1:3118 — connect any wallet and deposit; the AntSeed
   deposits contract holds the balance. Check it with `antseed buyer balance`:

3. Start a local buyer proxy pinned to the Tokaine seller peer (the proxy
   listens on http://127.0.0.1:8377 by default):

   antseed buyer start --peer 68cba51ef5f00f758af3e3130a7cd9c687130634

4. Send OpenAI Chat Completions requests to the local proxy. The API key can
   be any string; AntSeed meters usage and pays per request automatically:

   POST http://127.0.0.1:8377/v1/chat/completions
   {"model": "gemini-3-5-flash", "messages": [{"role": "user", "content": "hi"}]}

The proxy's GET /v1/models lists the available services.
