x402 Pipeline

HTTP payment requests become signed Proofnet receipts.

The 3-minute scriptapprox. 60 seconds per 100 words

Proofnet x402 starts with the familiar HTTP 402 idea: a machine requests a paid resource and receives a quote. Proofnet adds a signed session, policy approval, deterministic execution proof, attestor verification, settlement receipt, and optional Bitcoin Taproot pay-to-contract anchor. The node's ML-DSA-87 identity is also the payment credential. A reviewer can replay each stage from the local ledger instead of trusting a SaaS bill.

Revenue posture: x402 is the small-payment lane that can feed gas, AI inference, proof workflows, and receipts without routing every request through a centralized billing server.
