Dungeons and Dragons (Alternate) API
Overview
Open5e provides a comprehensive REST API for D&D 5th Edition SRD content, covering monsters, spells, classes, magic items, and more. It supports HTTPS, CORS, and requires no API key, making it very beginner-friendly and browser-compatible. This is an excellent alternative to the standard D&D API when you need a wider content selection including third-party materials.
Beginner Tip
Open5e offers a search endpoint (?search=) that works across all content types at once — try it to discover spells, monsters, and items by keyword. The API returns paginated results, so check the next field in the response to load more.
