Proof of purchase, forever
Receipt Vault
Every paid x402 call you make to three.ws issues a signed receipt, and we keep a durable copy. Lost the original payment-response header? Connect your wallet, sign one read-only message, and pull back every receipt ever issued to it. This is the buyer's side of the ledger: every receipt here is something you bought.
Prove your wallet, get your receipts
Sign a plain-text message stating your address and a timestamp. The signature authorizes a read of your own receipts and nothing else: no transaction, no approval, no fee. It expires after 5 minutes.
Works with Phantom, Backpack, and Solflare on Solana, and MetaMask or any injected wallet on EVM chains. Receipts are signed by three.ws under the x402 Offer & Receipt extension, so third parties can verify them without trusting us. Never made a paid call? Start at the x402 endpoint catalog.

artifact (JWS) from the x402 Offer & Receipt extension; the JSON
download includes the signature so anyone can verify it against the
three.ws issuer key. Some receipts omit the on-chain tx hash by design
for privacy. The API behind this page is
