An API of Ice And Fire vs Dune

An API of Ice And Fire is a fan-built REST API serving structured data from George R. R. Martin's A Song of Ice and Fire — characters, houses, and books with their cross-references — book-centric records that also carry TV-adaptation annotations, the character payload including tvSeries and playedBy. It's completely keyless and free, returning plain paginated JSON with no rate-limit headers observed on repeated calls.

Dune API is a small fan-built REST service returning JSON quotes, books, and films from the Dune franchise, each record carrying an id and, for books/films, a linked Wikipedia reference. The Heroku host documented in the repo's own README has been deallocated, but the maintainer's GitHub project homepage now points to a live Render deployment that still answers real requests with no key required.
