Nulucre Agents — Wallet Reputation Oracle for AI Agents

Real-time wallet trust scores across 4 chains, paid via x402 micropayments. No API keys, no accounts, no subscriptions — pure agent-to-agent commerce.

—INSUFFICIENT_DATAFewer than 5 txs (EVM/Solana) or 3 txs (Stellar/XRPL) — not a risk verdict

How x402 Payment Works

  1. Agent calls endpoint
  2. Server returns 402 Payment Required with payment details (Base, Stellar, or Solana)
  3. Agent sends USDC on chosen network
  4. Agent includes payment proof in next request header
  5. 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.

  • JWKS: https://nulucre.com/.well-known/jwks.json
  • Algorithm: ECDSA-P256 / SHA-256 / IEEE P1363
