## Tools (as reported by the server, not verified)

- `x402\_verify`: Verify one or more XDR-1 signed receipts offline \(free\). Returns valid/invalid per receipt with signer recovery, declared signer comparison, and integrity digest. Supply raw\_receipt as JSON string or array for batch.
- `price\_lookup`: Look up pricing for any code402 tool \(free\). Returns current x402 pricing tiers, accepted networks, and tool availability. Use tool\_name for named lookups or url for URL-based lookups.
- `iban\_check`: Paid \($0.0029\). Validate an IBAN: ISO 13616 structure, country registration, length, MOD 97-10 checksum. Returns pass/fail with all checks and issues. Covers 50 countries.
- `sanctions\_check`: Paid \($0.0029\). Screen Ethereum addresses and entity names against OFAC/UN/EU sanctions lists. Returns clear/hit with matched entries. Supports both EVM addresses and human-readable names.
- `onchain\_address\_check`: Paid \($0.0029\). Validate an EVM address format and EIP-55 mixed-case checksum. Returns valid/invalid with normalization and checksum status.
- `lei\_check`: Paid \($0.0029\). Validate a Legal Entity Identifier \(LEI, ISO 17442\). Checks 20-char alphanumeric format and Mod 97-10 check character. Verified via Rust WASM engine.
- `luhn\_check`: Paid \($0.0029\). Validate a payment card or account number using the Luhn algorithm \(ISO/IEC 7812-1\). Checks numeric format and Mod-10 checksum. Verified via Rust WASM engine.
- `mod97\_check`: Paid \($0.0029\). Calculate ISO 7064 Mod 97-10 remainder for any alphanumeric string. Returns the remainder \(0-96, valid=1\). Used for IBAN, LEI, and custom identifier validation. Verified via Rust WASM engine.
- `bundle\_verify`: Paid \($0.0029–$0.50\). Multi-gate compliance bundle: run any combination of IBAN validation, sanctions screening, and EVM address validation in a single call. Returns all gate results + XDR-1 signed receipt. Tier auto-detected from field count.
- `chain\_block\_number`: Paid \($0.0029\). Get the latest Ethereum mainnet block number. Returns block height and timestamp.
- `chain\_balance`: Paid \($0.0029\). Get native ETH balance of any Ethereum address. Returns balance in wei and ETH.
- `chain\_erc20\_balance`: Paid \($0.0029\). Get ERC-20 token balance via balanceOf. Returns balance in raw and human-readable form.
- `chain\_nonce`: Paid \($0.0029\). Get the next transaction nonce for an Ethereum address.
- `chain\_tx`: Paid \($0.008\). Get Ethereum transaction details by hash. Returns from, to, value, gas used, status, block info.
- `chain\_ens\_resolve`: Paid \($0.008\). Resolve a .eth ENS name to its Ethereum address via the universal resolver.
- `chain\_gas\_price`: Paid \($0.0029\). Get the current Ethereum mainnet gas price. Returns base fee, priority fee, and max fee in wei and gwei. Useful for estimating transaction costs.
- `chain\_tx\_receipt`: Paid \($0.008\). Get the receipt of a confirmed transaction. Returns status \(success/fail\), gas used, logs, contract address if deployment.
- `chain\_code`: Paid \($0.0029\). Get the deployed bytecode at an address. Returns hex bytecode \(empty = EOA, non-empty = contract\). Useful for distinguishing contracts from wallets.
