  65. 90api.duoleads.com/v1/num/radixConvert an integer between any two numeric bases from 2 to 36, with arbitrary precision so values far beyond 2^53 are exact. Accepts an optional sign and common prefixes (0x, 0b, 0o), validates every digit against the source base, and returns the value in the target base, in decimal, and as its bit length and digit count.$0.05 Base1766 ms1 payers100% up
  66. 90api.duoleads.com/v1/ref/countryLook up a country or territory by ISO 3166-1 alpha-2, alpha-3 or numeric code, or by name, and get the other codes, the official and common English names, the UN M49 region and sub-region, the currencies in use, the country-code top-level domain, and optionally the full ISO 3166-2 subdivision list with each subdivision's type. Also resolves an ISO 3166-2 subdivision code such as NL-NH directly. Names are matched case- and accent-insensitively.$0.05 Base1823 ms1 payers100% up
  67. 90api.duoleads.com/v1/ref/currencyLook up a currency by its ISO 4217 alphabetic or numeric code: the official English name, minor-unit exponent, fund flag, the smallest cash denomination where it differs from the minor unit, the territories that use it, and historic codes on request. Returns the correct rounding increment for cash amounts, which is what a caller needs to render or settle a price. This route returns currency facts only and never an exchange rate.$0.05 Base1715 ms1 payers100% up
  68. 90api.duoleads.com/v1/ref/airportLook up an airport by IATA or ICAO code and get its name, city, country, ISO 3166-2 region code, WGS-84 coordinates, elevation and IANA time zone, or find the nearest airports to a coordinate within a radius. Covers every airport worldwide that holds a three-letter IATA code and scheduled service. Returns the code type that matched and the distance in kilometres for proximity results.$0.05 Base1812 ms1 payers100% up
  69. 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. Returns the Latin-script and local-language names plus the urbanisation, coastal and mountain typologies.$0.05 Base1827 ms1 payers100% up
  70. 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 Base1763 ms1 payers100% up
  71. 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. Returns every chain the address is valid for (ambiguous when several match), the checksummed form for EVM addresses, and the reason a check failed, including unrecognised_format.$0.05 Base1504 ms1 payers100% up
  72. 90api.duoleads.com/v1/geo/distanceDistance and direction between WGS-84 coordinates: geodesic distance by Vincenty with a haversine fallback, initial and final bearing, the midpoint, and the destination point reached from a start point on a given bearing and distance. Also computes the cumulative length of a supplied coordinate path. Results in metres, kilometres, nautical miles and miles.$0.05 Base1463 ms1 payers100% up
  73. 90api.duoleads.com/v1/geo/polygonGeometric predicates on a GeoJSON geometry supplied in the request: point-in-polygon with correct hole handling, bounding box, centroid, signed area in square metres, perimeter length, and ring winding order. Accepts Polygon and MultiPolygon, and a GeoJSON Feature wrapping either. Area and length are geodesic on the WGS-84 ellipsoid, correct at any latitude; containment is planar in lon/lat.$0.05 Base1498 ms1 payers100% up
  74. 90api.duoleads.com/v1/geo/pluscodeEncode coordinates as an Open Location Code (plus code) at a chosen length, or decode a full code back to its bounding box and centre. Also shortens a full code against a reference coordinate and recovers a shortened code given a reference, which is how plus codes are normally exchanged in text. Returns code length, precision in metres and validity.$0.05 Base1069 ms1 payers100% up
  75. 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. Encoding also returns the eight neighbouring cells, which is what a caller needs to do proximity search over a geohash-indexed store without a spatial database.$0.05 Base1174 ms1 payers100% up
