  55. 90api.duoleads.com/v1/num/allocateSplit a money amount into shares without losing or inventing a cent. Divide evenly into N parts, or by a list of ratios, and the remainder is distributed one minor unit at a time by a named, deterministic rule — largest-remainder, first-wins or last-wins — so the parts always sum exactly to the original. Uses the ISO 4217 minor-unit exponent of the currency, so zero- and three-decimal currencies work (JPY 0, KWD 3); metals and XXX are rejected.$0.05 Base2102 ms1 payers100% up

  62. 90api.duoleads.com/v1/ref/nutsLook up a NUTS statistical region of the European Union: resolve a NUTS code to its name, country and level, walk up to its parents or down to its children, or search regions by name. Covers all four levels (country, major region, basic region, small region) for the 27 member states and 12 further reporting countries, from the NUTS 2024 classification.

  63. 90api.duoleads.com/v1/chain/selectorCompute the Keccak-256 hash of a Solidity function or event signature and derive the 4-byte function selector and the 32-byte event topic. Normalises the signature first — strips parameter names, expands uint to uint256 and the other aliases, flattens tuples — so a signature copied from source code produces the same selector as the canonical form. Also hashes arbitrary text or hex bytes with Keccak-256.$0.05 Base1901 ms1 payers100% up
  64. 90api.duoleads.com/v1/chain/addressIdentify which blockchain an address belongs to and validate its encoding: EVM EIP-55 checksum, Bitcoin base58check and bech32/bech32m with witness version, Solana base58 and on-curve check, Cosmos bech32 with its HRP, Tron, XRP, Litecoin, Dogecoin, Cardano, Polkadot SS58 and Algorand.

  68. 90api.duoleads.com/v1/geo/geohashEncode a WGS-84 latitude and longitude to a geohash at a chosen precision, or decode a geohash back to its bounding box, centre point and error bounds in metres.
