An API of Ice And Fire vs STAPI

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.

STAPI is a deep, independently maintained REST API covering Star Trek canon across every series and film — tens of thousands of records in aggregate across dozens of resource types (7,571 characters, 6,822 performers, 1,443 spacecraft, 860 episodes and 759 species when measured live), each with dozens of structured fields (birth dates, ranks, serial numbers, alternate-reality flags). Queries go through POST search endpoints under /api/v1/rest rather than simple GETs, and no key is required.
