  title: SWAPI - Star Wars Films Planets API
  description: "SWAPI (Star Wars API) is a free, open Star Wars REST API. It exposes canonical\nStar Wars data — films, people, planets, species, starships, and vehicles — across\nthe original and prequel trilogies and the Clone Wars era. SWAPI is widely used\nas a teaching API for REST clients, framework demos, MCP server tutorials, and\nJSON parser benchmarks.\n\nTwo community mirrors are commonly used:\n  - swapi.dev   (Python/Django port maintained by @juriy)\n  - www.swapi.tech (Node/MongoDB port maintained by @semperry)\n\nThe original swapi.co project (by Paul Hallett / @phalt) is no longer maintained.\nThis OpenAPI describes the swapi.dev surface, which preserves the canonical SWAPI\nresponse shape (count / next / previous / results paginators and the flat resource\nschemas). The swapi.tech mirror wraps the same payloads inside `result.properties`.\n"
