Payroll & Salary API

Gross-pay maths as an API — the everyday salary and wage calculations, computed locally and deterministically and entirely currency-agnostic. The convert endpoint turns a pay figure given at any cadence — annual, monthly, bi-weekly, weekly, daily or hourly — into all the others, using configurable hours per week, weeks per year and days per week. The overtime endpoint computes regular, overtime (time-and-a-half by default) and double-time pay from the hours worked, with adjustable thresholds and multipliers, and reports the effective hourly rate. The raise endpoint applies a percentage or fixed raise, or works out the percentage from a new salary. The prorate endpoint pro-rates a salary by a worked fraction, or by days worked over days in the period — for joiners, leavers and part-periods. Everything is gross pay only: it deliberately excludes tax, deductions and benefits, which are jurisdiction-specific, so the maths stays exact and never goes stale. Computed locally, instant and private. Live, nothing stored. 4 endpoints. Ideal for HR and payroll tools, job boards and offer calculators, freelance and contractor rate tools, and budgeting apps. This is gross-pay maths; for loan, interest and investment maths use a finance-calculator API, and for net/take-home pay apply your local tax rules separately.

Tax Bracket API
Progressive (marginal) tax-bracket maths as an API. You supply the bracket schedule, so it works for any country, year or tax table and never goes stale, and it is entirely currency-agnostic. The tax endpoint takes an income and a schedule of threshold:rate pairs (with an optional standard deduction) and returns the total tax, the after-tax income, the effective and marginal rates, and a per-bracket breakdown showing exactly how much is taxed in each tier. The reverse endpoint solves the inverse problem — the gross income needed to take home a target net amount on the same schedule — by bisection. The brackets endpoint validates and normalizes a schedule into labelled tiers (adding a 0% tier from zero and marking the open-ended top bracket). Everything is computed locally and deterministically, so it is instant and private. It models only the schedule you provide — fold any allowances, credits or surtaxes into the brackets or the deduction yourself — and it is not tax advice. Ideal for payroll and HR tools, salary and offer calculators, fintech and budgeting apps, and any product that shows take-home pay. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is progressive-tax maths on a schedule you supply; for gross-pay period conversion use a payroll API and for loans and interest use a finance-calculator API.

College Majors API
Earnings and employment outcomes for 170+ US college majors, from FiveThirtyEight's analysis of the U.S. Census American Community Survey. For each major: its category (Engineering, Business, Arts…), number of graduates and share who are women, median / 25th- / 75th-percentile earnings of full-time workers, unemployment rate and college-job counts. Look a major up by name or code, list a category, rank majors by earnings or unemployment, or search. Ideal for edtech, career-guidance, student-advising and HR analytics apps.

Programming Languages API
The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.
