Mycelia Signal Documentation

Cryptographically signed price attestations over Lightning (L402) and USDC on Base (x402). No API keys. No accounts. One HTTP call.

Start here

Get your first signed price attestation with a single curl command. Includes both L402 and x402 examples.

Verify attestation signatures in Python, JavaScript, and Rust. Reconstruct the canonical payload and validate the proof.
