CKB Fiber Hackathon · Live Demo

The internet forgot
to build payments.

HTTP 402 has existed since 1996. Others tried to implement it - Coinbase x402 on Base, Lightning L402 - but gas fees and settlement speed make sub-cent payments unviable. Fiber-402 is the first implementation where $0.001 AI agent micropayments actually work.

HTTP/1.1 402 Payment Required
defined 1996 · finally viable · on Fiber
