Authentication

All of the Symbolab APIs require authentication strings provided in the headers of the request. The authentication is comprised of two identification strings:

1. app_id: a string identifying the application that is using the API
2. access_key: a string indicating the access permissions to the different API calls.

Caller Question Format

Symbolab APIs accept a question field. The question field should be a string containing the question being asked. The question can be either text input or image input or a mix of both.

To indicate images use <image>...</image> tags. You can either specify a URL of the image - for example:

<image>https://www.symbolab.com/image.jpg</image>

or provide the image as Base64 content using data URI:

<image>data:@file/jpeg;base64,/9j/4AAQSkZJRgA...</image>

Symbolab Question Format

Symbolab APIs will convert caller question format into Symbolab question format.

The Symbolab Question format is a unambiguous input that returns a single answer from Symbolab's calculators. For example if a caller's question is:

f(x)=x+2/x,

the Symbolab Question will become

domain f(x)=\frac{x+2}{x}

You can use the /api/vi/dym API to retrieve multiple alternatives to a caller question. Symbolab will use the first alternative when an API is being called with 'question' field.

When symbolab_question is provided, the question field will be ignored and no auto-corrections will be performed.

Supported Languages

Symbolab offers its API service in the following languages:

• Arabic - ar

Rendering LaTeX

We recommend using KaTeX as the LaTeX rendering engine. LaTeX will reside within the math delimiters, usually $$...$$.

API Demo Limitations

The API demonstration key can only be used to solve queries with result_type = solution_only or flat_steps, and it can only be used to ask algebraic and pre-algebraic questions. Additionally, there is a 50 request per hour limit on the present API demonstration.
