Top Free Math APIs for Developers in 2018

Math Web APIs

An application programming interface is a term used in computer technology to define protocols, grouped subroutine definitions and tools that are brought together to build an application software such as math APIs.

Math, on the other hand, has no definition that is generally accepted but patterns are used in the formulation of conjectures, in topics like quantity, space, structures, and change, and these patterns state the truth or falsify these conjectures.

Since the evolvement of computers and technology, it has been used to make work not only more comfortable but also has dramatically increased the speed of performing functions.

Mathematics is one of these functions that has been integrated into computer technology as after all one of the first advancements in technology was calculations.

Math APIs are thus the protocols and tools that enhance communication between the components of the given software to solve mathematical problems or use math to provide specific information.

Here is a list of some of the best math rest APIs available on RapidAPI:

1. Newton API

Numbers API

Numbers API Package cultivates your interest in numbers by providing trivia and facts about numbers and other related mathematical queries you may have.

List of Endpoints

• Get-Date Fact – Provides a fact about a particular date of the year explicitly.
• Get Math Fact – Provides you with a mathematical feature of a certain number
• Get Random Fact – Returns a result on a certain amount Get Trivia Fact – The user is provided with a trivia fact about a specific number
• Get Year Fact – Returns a year with a point to the requester.

How to acquire an API Key

Like the Newton API, you don’t need a Numbers API Key.

Your RapidAPI key is provided with every code snippet as the “X-Mashape-Key” and can also be found in your RapidAPI Dashboard under the “Security” tab of your application.

Pricing

The Numbers API is another free to use API on the RapidAPI marketplace.

3. Equa Images API

The Equa Images API allows you to convert math formulas or equations to an image in the PNG format.

List of Endpoints

• GET equaimage – input any equation and the API will convert it into an image.

How to acquire an API Key

With RapidAPI, you don’t need an API Key. Once you’re subscribed to a pricing plan, you will use your RapidAPI API key to make your requests to the Equa Images API.

1. Log in or sign up for a Free RapidAPI account.
2. Navigate to Equa Images API package page.
3. Subscribe to a pricing plan.

Your RapidAPI key is provided with every code snippet as the “X-Mashape-Key” and can also be found in your RapidAPI Dashboard under the “Security” tab of your application.

Pricing

The Equa Images has a free tier that allows for 10 calls per month.

1. Basic – $0.00 for 10 calls/month
2. Pro – $9.99 for 1,000 calls/day
3. Ultra – $24.99 for 3,000 calls/day
4. Mega – $49.99 for 10,000 calls/day

4. MathPI API

The MathPI API generates LaTeX formulas from the formula inputted by the user. Like the Equa Images API, it returns an image in a PNG format.

List of Endpoints

 

• API Version – Retrieves the current version of the API.
• Generate Image from LaTeX – This endpoint generates the PNG image of your equation or formula.

How to Acquire API Keys

No MathPI API key required, just need the RapidAPI Key listed as “X-Mashape-Key” in your account.

Pricing

The MathPI is free to use up to 10,000 API calls per month. Following that, it’s $0.001 per extra call.

5. Qalc API

The Qalc API is a mathematical API that cleans up your equations and formulas.

For example, if you had an input of “3*2”, the response would be “6”.

List of Endpoints

• Calculate – The only endpoint is Calculate, which cleans up your inputted expression.

How to acquire an API Key

Qalc API is another fully integrated API on RapidAPI.com. You just need your RapidAPI key (aka “X-Mashape-Key” parameter).

Pricing

The Qalc API has a Basic and Pro Plan:

1. Basic – $0.00 for 200 calls/day
2. Pro – $10.00 for 1,000,000 calls/month
