business_days_calculateBusiness days calculator with a caller-supplied calendar: add or subtract N working days from a date, or count the working days between two dates. The weekend is a weekday mask (Friday-Saturday and Sunday-only weeks work) and holidays are an explicit date list, so nothing depends

geohash_encode_decodeGeohash encoder and decoder: encode 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 pr

IBAN, ISIN, VAT/tax ID and GTIN barcode validation plus 29 more utilities for AI agents. Pay per call ($0.05 USDC on Base via x402), no API key, no signup.
Timezone and DST, geo distance and geohash, hashes and JWT decoding, airport, country, currency and NUTS lookups, money split, base conversion and more. Every call is one HTTP GET, paid per request.
Also crypto derivatives data for trading agents: perp funding rates, funding arbitrage, open interest, futures basis, implied volatility, liquidations and order book depth across Bybit, Hyperliquid, dYdX, Gate, Kraken, Bitfinex, Deribit and OKX, at $0.003 or $0.005 per call (below).
npm install duo-data-utilities viem
viem creates the wallet account that pays. This package also depends on it. Node.js 20 or later.
Python (not on PyPI, install from GitHub):
pip install "git+https://github.com/hiesem/duo-data-utilities#subdirectory=python"
import { privateKeyToAccount } from "viem/accounts";
import { createClient } from "duo-data-utilities";
// Your wallet holds USDC on Base. Read the key from the environment, never a literal. const client = createClient({ account: privateKeyToAccount(process.env.DUO_PAYER_KEY as 0x${string}) });
const iban = await client.iban.validate({ iban: "NL91 ABNA 0417 1643 00" }); // $0.05 console.log(iban.valid, iban.country); // true NL
checkCounterparty runs three checks in one call: IBAN (/v1/id/iban), tax ID (/v1/id/national) and country (/v1/ref/country). It costs $0.15.
const check = await client.checkCounterparty({
iban: "NL91 ABNA 0417 1643 00", country: "NL", taxIdType: "bsn", taxId: "111222333", }); console.log(check.verdict, check.reasons); // "pass", "fail" or "review"
fail: the IBAN or the tax ID fails its checksum, the country is not an ISO 3166-1 country, or the API rejects an input as malformed.review: the IBAN country differs from the tax ID country, or the API does not cover that country or tax ID kind.pass: every check passed.Structure and checksum only. The check does not query a company register, a bank or a tax authority, and it does not confirm that an account exists. UK is read as GB.
client.derivs calls https://derivs.duoleads.com: crypto derivatives data from 8 exchanges (Bybit, Hyperliquid, dYdX, Gate, Kraken, Bitfinex, Deribit, OKX) for trading agents and bots. Perpetual futures (perp) funding rates with predicted funding, funding rate history and a funding arbitrage scanner, a perp screener, open interest (OI), futures basis and term structure, options implied volatility (IV), skew and max pain, liquidations, and order book depth with slippage. $0.003 or $0.005 per call, same wallet, same x402 payment, no API key.

client.derivs has its own cap, $0.005 per call by default. createClient({ account, derivs: { maxPriceUsd: 0.003 } }) refuses the $0.005 routes (Python: derivs_max_price_usd=0.003). The other rules are the same: Base USDC only, only to 0xCD673f7e1daD254347AEab6be0DEFe8b9C6b3A39, nothing is signed before the check.error.expected. When fewer venues answer than the route needs, the answer is a 503 and nothing is charged. Both throw DuoApiError.data envelope), with venues_missing, units, as_of and a see_also pointer to the next useful route.
