About Quoterism

Quoterism provides a REST API for retrieving inspirational quotes from famous authors, philosophers, and leaders. The API exposes a single endpoint for fetching a quote by ID, including special identifiers for a random quote or the quote of the day (aliased as "qotd"). Each response includes the quote text along with author details such as name, slug, and image URL.

Access requires an API key, obtained by creating an account and requesting one from the user profile. Usage is capped at 30 requests per minute and 150 per day, with keys that repeatedly exceed the daily limit subject to a 7-day suspension; the documentation recommends implementing exponential back-off and honoring Retry-After headers.

The API is aimed at developers building applications that need programmatic access to quote content, such as daily motivation features or quote-of-the-day displays. The base URL for requests is https://www.quoterism.com, and authentication is done via an X-API-Key header.
