Statutory income tax on a taxable-income figure: per-bracket workings, effective + marginal rate

URL parser: parse and canonicalise a URL, and extract its registrable domain using the Public Suffix List — the part an agent needs to decide whether two URLs belong to the same owner. Returns scheme, host, port, path, decoded query parameters and fragment, the public suffix, the registrable domain (eTLD+1), the subdomain, whether the suffix is ICANN or private, plus a canonical form with default port, dot-segments and percent-encoding normalised. unicode_host uses WHATWG/UTS 46 (non-strict).

Wage check: is this salary legal vs statutory minimum wage? Verdict + margin + instrument

Snapshot of every series, all countries

VAT, tax ID and national ID validator: check a national identity, tax or company registration number against its country's official checksum rule. Covers 23 countries including NL BSN, ES NIF/NIE/CIF, IT codice fiscale, FR SIREN/SIRET, DE Steuer-ID, BE/PL/CZ national numbers, SE/NO/DK/FI personal numbers, BR CPF/CNPJ, AU ABN/TFN, UK NINo, IE PPS, US NPI/EIN. Structure and check digit only, no registry lookup; the number is never stored (logs keep only its length and character types).

Strait of Hormuz war-risk transit premium nowcast: a live MODELED war-risk insurance multiple (Nx over the peace baseline, 1x-80x scale) for a tanker transit, recomputed every 5 minutes from throughput deviation (IMF PortWatch), the escalation forecast, crude implied volatility (OVX) and event pressure. Returns a band, a curated VLCC premium band ($/voyage, estimated separately), per-driver detail and a confidence that drops on stale feeds. A modeled indicator, not an insurance quote.

Search scholarly papers: title, year, first authors, venue, citation count, DOI and a free full-text link when one exists, most relevant first.

Google Trends interest by region for one keyword: 0-100 interest per subregion of a country (or per country worldwide), past 7 days to 5 years, in one $0.03 GET. Use when you need where a keyword is searched most, for geo-targeting or local market research. A live call takes up to about 30 s. Bad input is free; upstream errors are not charged.

Strait of Hormuz bunker & marine-fuel feed: current VLSFO, IFO380, and MGO prices ($/tonne) for Fujairah (the world's #2-3 bunkering hub, just outside the strait and the physical fueling alternative when transit is disrupted), benchmarked against Singapore and Rotterdam, plus the derived Fujairah premium over each comparison hub. The physical-commodity read on Hormuz stress that the Brent and insurance signals do not capture.

How do I fix my broken x402 endpoint? Diagnoses it, then returns per problem the concrete change as code for your stack (Express, Next.js, Hono or raw HTTP), filled in with your own payTo, amount, network and route. Bulk: 1000 credits for $0.80 via /api/v1/credits.

Belgian company lookup in the official KBO/BCE Crossroads Bank for Enterprises (Daily data) by enterprise number (0417.497.106 or BE0417497106) or company name. Returns legal name, status, legal form, start date, registered address, NACE activities and website in a schema shared across countries.

Money split: split 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.

Currency lookup by 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.

Base converter: convert an integer between any two numeric bases from 2 to 36 (hex, binary, octal and more), 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.

Plus code (Open Location Code) encoder and decoder: encode coordinates as a 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.
