Introduction

A credit-based, OpenAI-compatible LLM gateway. Pay with USDC/USDT via x402 — no accounts, no KYC.

Token Kiosk is a credit-based LLM inference gateway. It sits between your app and LLM providers, giving you a single OpenAI-compatible API to access multiple model providers.

Driving this with an AI agent?

Jump to For AI Agents — the gateway is OpenAI-compatible, so it's a one-line base-URL change. Machine-readable contracts: /openapi.yaml, /llms.txt, /llms-full.txt.

How it works

The 3-step flow

Step	What	How
1. Top up	Fund your balance	Send USDC or USDT via x402 — no accounts, no KYC
2. Get API key	Prove wallet ownership	Sign a SIWE message, receive `sk-...` key
3. Call the API	Use any model	Standard OpenAI SDK with `Bearer sk-...`

Why use this?

No vendor lock-in — switch models by changing a string (gemini/gemini-2.5-flash → kimi/kimi-k2.5)
No accounts — your Ethereum wallet is your identity
No KYC — pay with USDC or USDT, get credit instantly
OpenAI-compatible — use the openai SDK, the Vercel AI SDK, or raw fetch
Transparent pricing — billed at downstream provider cost, all queryable via /v1/usage
