SWAPI.build
A free, open-source Star Wars API serving data about People, Films, Planets, Species, Starships, and Vehicles. Built with Quarkus and GraalVM for instant startup, minimal memory footprint, and out-of-the-box performance.
Inspired by the original SWAPI (created by Paul Hallett, maintained by Juriy Bura), this project was born out of the need for a Star Wars API that never goes offline. If you've ever had a live demo break because a third-party API went down, you know why this exists.
Quick Start
Prerequisites: Java 25 and Maven (or use the included Maven Wrapper).
cd swapi-app
./mvnw quarkus:dev
The API and frontend will be available at http://localhost:5432.
API Endpoints
Base path: /api
| Resource | List All | By ID | Random | Search |
|---|---|---|---|---|
| People | GET /api/people | GET /api/people/:id | GET /api/people/random | GET /api/people?search=name |
| Films | GET /api/films | GET /api/films/:id | GET /api/films/random | GET /api/films?search=title |
| Planets | GET /api/planets | GET /api/planets/:id | GET /api/planets/random | GET /api/planets?search=name |
| Species | GET /api/species | GET /api/species/:id | GET /api/species/random | GET /api/species?search=name |
| Starships | GET /api/starships | GET /api/starships/:id | GET /api/starships/random | GET /api/starships?search=name |
| Vehicles | GET /api/vehicles | GET /api/vehicles/:id | GET /api/vehicles/random | GET /api/vehicles?search=name |
Ids are the record ids from each entity's url field (for films, 1 = A New Hope).
Successful responses return 200; unknown or non-numeric ids return 404.
GET /api/stats returns anonymous request counts per route (for example
/api/people/{id} or /mcp) and per group (REST API, MCP, pages, SEO, other)
for the last 24 hours (?period=24h, per hour), 7 days (default, per day;
&granularity=hour for hourly) or 30 days (?period=30d, per day), each with
the window before it for comparison, plus server response times per route and
per group under performance (requests, mean, min, max, standard deviation and
approximate p50/p95/p99 in milliseconds, network excluded). They are counted with
no IP address or client details. The /stats page
shows the same numbers with filters, a trend chart, a ranking and a Performance
section.
All responses are JSON. Example:
curl http://localhost:5432/api/people/1
OpenAPI
The full API contract is served at /openapi.json
(OpenAPI 3.x, generated from the code — always in sync). The
documentation page renders from it, including a
"try it" for every endpoint. Generate a client with, e.g.:
npx @openapitools/openapi-generator-cli generate -i https://swapi.build/openapi.json -g typescript-fetch
MCP Server
swapi.build is also a remote MCP server over
Streamable HTTP. Any Streamable HTTP client works: the stateless 2026-07-28
revision sends self-contained requests, and earlier revisions negotiate a session
through initialize — both are served on the same endpoint. The legacy HTTP+SSE
transport (2024-11-05) is not supported. First-party, read-only, no authentication:
https://swapi.build/mcp
Full setup guides: swapi.build/docs/mcp
| Tool | Arguments | Returns |
|---|---|---|
sw_list | resource | All entities of a resource |
sw_get | resource, id | One entity by id |
sw_random | resource | A random entity |
sw_search | resource, query | Name/title substring match |
resource is one of PEOPLE, FILMS, PLANETS, SPECIES, STARSHIPS, VEHICLES.
Ids are the record ids from each entity's url field (for FILMS, 1 = A New Hope).
Caching: Quarkiverse MCP Server 2.0.0 emits the required ttlMs: 0 and
cacheScope: "public" fields on stateless discovery and tool-list responses.
Zero TTL means immediately stale; no positive freshness period is configured.
Its cache hints
apply to discovery, list methods and resources/read, not tools/call.
The Star Wars data here is exposed through tools, so tool-result caching is not
enabled, including for sw_random. REST/edge caching is a separate mechanism.
claude mcp add --transport http swapi-build https://swapi.build/mcp
Or share via .mcp.json at the repo root:
{
"mcpServers": {
"swapi-build": { "type": "http", "url": "https://swapi.build/mcp" }
}
}
Verify: claude mcp list → swapi-build ✔ Connected.
Settings → Connectors → Add custom connector → name swapi-build, URL
https://swapi.build/mcp. No authentication needed. Verify in any chat via the + menu → Connectors.
codex mcp add swapi-build --url https://swapi.build/mcp
Or in ~/.codex/config.toml (shared by CLI, IDE extension and ChatGPT desktop):
[mcp_servers.swapi-build]
url = "https://swapi.build/mcp"
Verify: codex mcp list.
.vscode/mcp.json (top-level key is servers):
{
"servers": {
"swapi-build": { "type": "http", "url": "https://swapi.build/mcp" }
}
}
Or Command Palette → MCP: Add Server. Verify via the Configure Tools button in Copilot Chat. On Business/Enterprise, the "MCP servers in Copilot" org policy must be enabled.
~/.bob/settings/mcp_settings.json (global) or .bob/mcp.json (project):
{
"mcpServers": {
"swapi-build": {
"type": "streamable-http",
"url": "https://swapi.build/mcp",
"disabled": false
}
}
}
Or Bob panel → MCP tab → Edit Global MCP. Bob detects the tools automatically.
The server scales to zero when idle — if the very first connection attempt fails, retry once (the native binary starts in tens of milliseconds; the platform may take a bit longer to provision the container; subsequent calls are fast, whether your client is stateless or session-based).
WebMCP in the browser (experimental)
The website exposes sw_list, sw_get, sw_search and sw_random through
WebMCP. Names and arguments match the remote MCP tools, including uppercase
resource names. Each browser tool updates the visible explorer and returns
complete records in a JSON result with ok, data, resource and path.
The browser result envelope differs from the remote MCP transport.
Use a compatible browser with WebMCP enabled and the document.modelContext
API. The setup and demonstration guide
explains the inspector, example calls and cancellation behavior. When the API
is unavailable, the site works normally. No model API key or AI runtime is
embedded in the site. The JavaScript is bundled by Quinoa and runs in the
browser, including when served by the Quarkus native executable.
Client examples
examples/java/langchain4j-mcp-client— ask questions in natural language; the tools come from the MCP server above, so the example defines none.examples/java/quarkus-rest-client— call the REST API from Java with a typed client.

Each backend domain (film, people, planet, etc.) follows the same pattern:
- Model (e.g.,
Film.java): POJO with@RegisterForReflectionfor native image support - Service (e.g.,
FilmService.java): loads data from JSON at startup, caches in memory - Resource (e.g.,
FilmResource.java): Jakarta REST controller with@RunOnVirtualThread
Build
cd swapi-app
# Development mode (live reload)
./mvnw quarkus:dev
# Production JAR
./mvnw package
java -jar target/quarkus-app/quarkus-run.jar
# Native executable (requires GraalVM or container build)
./mvnw package -Dnative
./mvnw package -Dnative -Dquarkus.native.container-build=true
The frontend is automatically built and bundled by Quinoa during the Maven build. No separate npm step is needed.
Deployment
The app runs as a native (GraalVM/Mandrel) executable on a self-hosted server on Oracle Cloud, managed by systemd behind Caddy (TLS via Let's Encrypt). DNS is managed on Cloudflare (DNS-only records pointing to the server). Publishing a GitHub Release runs .github/workflows/native-binary.yml: test suite, native build attached to the Release, a manual approval, then the install on the server over SSH and the production probes. The runbook is docs/DEPLOY.md.
