• POST /evm/address-checksum — EVM address checksum and validation tool — normalize one Ethereum-compatible address and validate mixed-case EIP-55 input offline. (0.005 USDC on Base)
• POST /evm/abi-decode — Strict Solidity ABI calldata decoder — decode canonical EVM smart-contract function calls or typed values, verify selectors, and reject ambiguous offsets or padding. (0.005 USDC on Base)
• POST /merkle/build — Keccak Merkle tree and proof builder — generate indexed sorted-pair inclusion proofs with domain separation and explicit odd-node promotion. (0.01 USDC on Solana)
• POST /evm/create2 — CREATE2 deterministic contract address calculator — derive the EIP-1014 EVM deployment address, preimage, hashes, and EIP-55 checksum offline without RPC. (0.005 USDC on Base)
• POST /evm/abi-encode — Solidity ABI calldata encoder — encode canonical typed values for an EVM smart-contract function call, with an optional selector and exact 256-bit integers. (0.005 USDC on Base)
• POST /merkle/verify — Keccak Merkle proof verifier — validate inclusion plus exact leaf index and count proof shape for the Atlas sorted-pair tree profile. (0.005 USDC on Solana)
• POST /solana/pda — Solana Program Derived Address (PDA) calculator — derive the canonical off-curve address and bump from bounded public seeds offline, without RPC or key handling. (0.005 USDC on Base)
