Pay-per-Verify: an agent pays $0.01 to verify a post-quantum (ML-DSA-65 / Dilithium-3 or Dilithium-2, NIST FIPS 204; scheme auto-detected by size) signature over a message against a public key. A generic machine-to-machine PQC proof primitive for autonomous agents. x402-native.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://fractalai.net.co/api/x402/verify-proof' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://fractalai.net.co/api/x402/verify-proof'
Endpoint: https://fractalai.net.co/api/x402/verify-proof. Operated by fractalai.net.co, not by Animica. Price and availability were correct at the last probe on 2026-10-01 and are set by the operator, who may change them.
