How x402 Payment Works

Agent calls endpoint
Server returns 402 Payment Required with payment details (Base, Stellar, or Solana)
Agent sends USDC on chosen network
Agent includes payment proof in next request header
Server verifies and returns score

No accounts. No API keys. Fully autonomous.

Cryptographic Verification

Signed endpoints return an ECDSA-P256 signature verifiable against the Nulucre public key.
