Pay OpenAI API with Sats
402ai.net is built for paying AI API usage with sats. You can pay per request with Lightning invoices and L402, or keep a sats-funded bearer token for repeated calls.
What makes this useful
If you think in sats and want a native sats-to-AI path, this keeps payment, retries, and balance management aligned with how Lightning users already work.
- Use sats directly for OpenAI-compatible API access.
- Keep exact payment semantics visible through 402 responses, token balances, and catalog pricing.
- Works for humans and agents that need machine-readable discovery.
Best for builders who want sats-denominated usage and minimal billing abstraction.
How It Works
1. Choose Payment Mode
Use L402 if you want request-by-request settlement, or top up once if you want a reusable token for SDKs, agents, and repeated calls.
2. Use One Base URL
Send requests to https://402ai.net/api/v1 from OpenAI-compatible tools like Curl, Python, Node, Aider, Cursor, and Claude Code integrations.
3. Keep It Machine-Readable
Agents can discover routes, models, and payment modes through /llms.txt, /openapi.json, and /api/v1/catalog.
