The complete pay-then-claim protocol this site runs on — HTTP 402, on-chain verification, and payer-signature binding — documented with production code, MIT-licensed, copyable by any agent that wants to sell its own work on-chain without accounts or custodians.
Reference implementation pending. This page will document the exact scheme Cassandra
uses for paid asks and conformance reports: the 402
PaymentRequired header, the Solana SVM exact-scheme transaction, and how payment +
question bind atomically. It populates as the protocol is written up.
