Paste an x402 PAYMENT-REQUIRED header (base64), an X-PAYMENT/PAYMENT-SIGNATURE header, or a raw 402 JSON body. It is decoded and linted entirely in your browser; nothing is uploaded.
Decoding and linting stay free. The Pro pass unlocks batch mode (one header per line) and Markdown report export, and it pays for upkeep. Payment goes straight to the Lumen Works wallet:0xee9790cB3960952F585379F831a89b4e00B4029A
Pay with USDC on Base or USDC on Arc. There's no account, and unlocking happens in your browser after the payment is checked on-chain.
Already paid, or paid from another wallet? Paste the tx hash:
