SYNTHORA Onchain Primitives: multichain (Base/Ethereum/Polygon/Arbitrum/Optimism) transaction receipts, tx lookup, wallet nonce, contract/proxy (EIP-1967) detection, ENS resolution, ERC20 + native balances, contract introspection. Deterministic, Ed25519-signed. 0.001 USDC via x402 on Base. First 3 calls FREE per wallet — send header 'X-WALLET: 0x<your Base address>' (no payment); after that 0.001 USDC per call.
