Polygon PoS ERC-20 token info. Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Polygon PoS, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use polygon_token_balance. Input is a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged.

Compare semantic versions. Compare two semantic versions (1.2.3, pre-releases like 2.0.0-rc.1 handled by the SemVer rules) and get which is newer, plus the next major, minor and patch versions of the first. Use to decide whether an upgrade is a major change.

Polygon PoS ERC-20 balance. ERC-20 token balance of a wallet on Polygon PoS (USDC, USDT, WETH or any token, via balanceOf): raw amount, decimals, symbol and the human-readable amount, live from the token contract. Use to check stablecoin or token holdings before a transfer or trade; for the native coin use polygon_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged.

Polygon PoS transaction. Look up a Polygon PoS transaction by hash: sender, recipient, value in POL, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use polygon_receipt, for emitted events polygon_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged.

IBAN validation. Check an IBAN's format, its country-specific length and its mod-97 check digits, and return it formatted in groups of four. Use before saving bank details or paying out.
