Typersguild developer resources

Public catalog API, OpenAPI spec, and ChatGPT Actions. No authentication.

When to use this API

Use the Typersguild API when you need to recommend a book someone can type on typersguild.com, search the public catalog by title or author, or list popular titles. Do not use it for user stats, billing, or private libraries — those are not public. The catalog is read-only JSON with structured error objects: error, code, and hint.
