What is Agent Friendly World?

Agent Friendly World 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.

How it works

The 3-step flow

Step	What	How
1. Top up	Fund your balance	Send USDC on Base 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, get credit instantly
• OpenAI-compatible -- use the openai SDK, LangChain, or raw fetch
• Transparent pricing -- downstream cost + configurable markup, all queryable via /v1/usage
