Every payload is cryptographically signed and EIP-712 PayloadAttestation provenance-stamped — covering crypto markets, DeFi yields, weather, earthquakes, news, code-pulse, threat-intel, and a slashable fact-oracle. Pay per call in USDC over x402 with no API keys — a wallet, not a secret on the box. Settlement is on Base (eip155:8453).
