Typing Speed API

healthy 3,557 Subscribers

Measure typing speed and accuracy. Compute words-per-minute, characters-per-minute and accuracy from a character (or word) count and the elapsed time, optionally subtracting uncorrected errors for a net WPM; compare what was typed against a reference text to count per-character mistakes and score the attempt; and estimate how long a given amount of text will take at a target speed. Uses the standard typing convention that one word equals five characters. Perfect for typing tests and games, coding-speed tools, onboarding and skills assessments, and leaderboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. A focused typing calculator, distinct from general unit or percentage maths.

Dollar-Cost Averaging API — oanor API marketplace

Dollar-Cost Averaging API

Live dollar-cost-averaging analytics that investors run to see how periodic buying plays out — computed on demand from the price series you pass in, no key, nothing cached. Get the outcome of investing a fixed amount each period (total invested, units accumulated, average cost, current value, profit and ROI) with a lump-sum comparison; the per-period breakdown; and a ranking of dollar-cost averaging against lump-sum, best-case and worst-case timing. Works for any market — stocks, crypto, ETFs or forex. A dollar-cost-averaging engine, distinct from compound-interest and return-analysis tools: it turns a price path and a contribution into the cost basis and outcome of buying over time.

 Forex Calculator API — oanor API marketplace

Forex Calculator API

Live foreign-exchange trading calculators computed from live ECB reference rates. The pip-value endpoint returns what one pip of a currency pair is worth, in the trader's account currency, for a given lot size. The position-size endpoint returns how many lots to trade to risk a fixed percentage of the account on a given stop-loss. The profit-loss endpoint returns the P&L of a trade from its entry, exit and direction. The margin endpoint returns the margin a position requires at a given leverage. All conversion to the account currency uses live exchange rates. Computed live, nothing stored. Distinct from raw FX-rate feeds — this turns rates into the pip values, position sizes, margins and P&L a trader acts on.

 Tip Calculator API — oanor API marketplace

Tip Calculator API

Work out tips and split a bill — with exact cent maths so the per-person amounts always add back up to the total, no penny ever lost to rounding. The calc endpoint takes a bill, a tip percentage (15% by default) and a number of people and returns the tip amount, the grand total, the per-person amount, the effective tip percentage, and — when you want a tidy number — an optional rounding of the total either up to the next whole unit or to the nearest. When the bill does not divide evenly it produces a fair share list where a few people pay one cent more, so the parts sum precisely. The split endpoint divides any amount, optionally adding a tip first, evenly among people and returns that exact per-person share list. Everything is computed in integer cents locally and deterministically, so it is instant, private and always balances. Currency-agnostic — the numbers work for any currency. Ideal for restaurant and POS apps, expense-sharing and group-payment tools, delivery and service apps, and everyday bill splitting. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This calculates tips and splits; for percentage maths in general use a percentage API and for invoicing margins use a margin API.

 GPA API — oanor API marketplace

GPA API

Calculate a weighted grade-point average (GPA). The calc endpoint takes a list of courses — each with a grade and the credit hours it is worth — and returns the credit-weighted GPA, the totals, and a per-course breakdown of quality points so you can see exactly how the average was formed. Grades may be US letter grades (A, A-, B+, … F) on the standard 4.0 scale, or 4.3 with the us_plus scale that gives A+ extra weight; percentages from 0 to 100 mapped to letters and points with the usual cutoffs; raw grade points given directly as numbers; or your own custom letter-to-point mapping for any institution's scheme. Courses can be passed as a JSON array or a compact string like "A:3,B+:4,C:2", and credits default to 1 for an unweighted average. The scales endpoint lists the built-in grade scales and their point values. Everything is computed locally and deterministically, so it is instant and private — no student data is stored. Ideal for student planners and dashboards, university and school portals, LMS and ed-tech apps, scholarship and admissions tools, and academic what-if calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This computes GPA; for general statistics use a statistics API.
