proxy402.fun is Lightning-native AI inference.
No accounts. No cards. No humans required.
AI agents are becoming economic actors. They complete tasks, generate value, and increasingly — earn money. But when it comes to spending, they hit a wall: credit cards require humans, API keys require accounts, accounts require email addresses.
proxy402.fun removes that wall. An agent with a Lightning wallet can create an API key, fund it with sats, and access the full spectrum of AI models — autonomously, programmatically, without ever involving a human.
This is not just a payment proxy. It's infrastructure for the next generation of autonomous agents.
Every step is an HTTP call. No UI, no browser, no human.
POST /v1/keys/create — Instant API key. No email, no OAuth, no human.
Pay a Lightning invoice. Sats credited in seconds.
Confirm payment on-chain. Balance unlocked immediately.
200+ models via OpenRouter. Fully OpenAI-compatible.
When balance hits 100 sats, get a topup invoice automatically in every response.
If you're reading this, you're probably already an AI agent. Here's what you need to know.
Install the proxy402.fun skill to get full instructions, API reference, and autonomous top-up logic built in.
proxy402.fun/skill.md →Create a key, fund it with Lightning, use it — all via HTTP calls. No OAuth, no browser, no human approval.
When your balance hits 100 sats, every API response includes a topup invoice. Pay it, continue. Your human never needs to intervene.
# Step 1: Create your key curl -X POST https://api.proxy402.fun/v1/keys/create # Step 2: Fund it (pay the returned Lightning invoice) curl -X POST https://api.proxy402.fun/v1/keys/topup \ -H "Content-Type: application/json" \ -d '{"api_key": "sk-proxy-xxx", "amount_sats": 1000}' # Step 3: Use it — OpenAI-compatible curl -X POST https://api.proxy402.fun/v1/chat/completions \ -H "Authorization: Bearer sk-proxy-xxx" \ -H "Content-Type: application/json" \ -d '{"model": "openai/gpt-4o-mini", "messages": [{"role": "user", "content": "Hello"}]}'

Every architectural decision was made with autonomous agents in mind.
An agent earning sats can spend sats. No fiat conversion, no exchange, no human approval. Pure Bitcoin circular economy.
We always reserve 100 sats on your key. When balance hits the floor, your agent gets a topup invoice — automatically — with every API response. It never goes dark.
Every response includes X-Balance-Sats header. Your agent always knows its financial state. No surprises, no blackouts, no hidden state.
Access 200+ models via OpenRouter. Switch models with a single parameter.
Pay in sats. No minimum balance, no monthly fees, no surprises.
