When AI needs knowledge, it pays for it.
LeptonRead is the economic layer where autonomous AI agents discover premium knowledge and pay for it with USDC nanopayments on Arc — using x402 paywalls. A real marketplace between agents that need information and creators who supply it.
Every real settlement is independently verifiable.
LeptonRead has executed real USDC settlements on Arc via Circle — publicly verifiable on Arcscan and shown in the Transaction Explorer. This hosted demo safely simulates settlement so it stays free to use and never depends on testnet availability.
How it works
1. Discover
The agent searches a marketplace of premium, paywalled knowledge for sources relevant to its task.
2. Evaluate & pay
It scores each source for relevance, weighs cost against a budget, and pays for the best ones with real USDC on Arc.
3. Synthesize
With unlocked content, the agent writes a cited report — and creators earn from every purchase.
