spacedevs

Space launch and astronaut data from The Space Devs Launch Library 2.

spacedevs is a single pure-Go binary. It reads public data from ll.thespacedevs.com over plain HTTPS, shapes it into clean records, and prints output that pipes into the rest of your tools. No API key required (anonymous access, rate-limited to 15 req/hour).

The same package is also a resource-URI driver, so a host program like ant can address spacedevs data as spacedevs:// URIs.

Install

go install github.com/tamnd/spacedevs-cli/cmd/spacedevs@latest

Or grab a prebuilt binary from the releases, or run the container image:

docker run --rm ghcr.io/tamnd/spacedevs:latest --help

Usage

spacedevs upcoming                         # upcoming rocket launches
spacedevs upcoming --limit 20             # more results
spacedevs upcoming --search SpaceX        # filter by name
spacedevs launches --search Falcon        # all/historical launches
spacedevs astronauts --search Armstrong   # search astronauts
spacedevs agencies --type Government      # space agencies by type
spacedevs spacecraft --search Dragon      # spacecraft catalog
spacedevs --help                          # the whole command tree

Every command shares one output contract: -o table|json|jsonl|csv|tsv|url|raw, --fields to pick columns, --template for a custom line, and -n to limit. The default adapts to where output goes (a table on a terminal, JSONL in a pipe), so the same command reads well by hand and parses cleanly downstream.

spacedevs upcoming -o json | jq '.[].name'
spacedevs astronauts --search Gagarin --fields name,nationality,dob
spacedevs agencies --type Government -o csv

Serve it

The same operations are available over HTTP and as an MCP tool set for agents, with no extra code:

spacedevs serve --addr :7777    # GET /v1/upcoming  returns NDJSON
spacedevs mcp                   # speak MCP over stdio

Use it as a resource-URI driver

spacedevs registers a spacedevs domain the way a program registers a database driver with database/sql. A host enables it with one blank import:

import _ "github.com/tamnd/spacedevs-cli/spacedevs"

Then ant (or any program that links the package) dereferences spacedevs:// URIs without knowing anything about the API.

Development

cmd/spacedevs/   thin main: hands cli.NewApp to kit.Run
cli/             assembles the kit App from the spacedevs domain
spacedevs/       the library: HTTP client, data models, and domain.go (the driver)

make build      # ./bin/spacedevs
make test       # go test ./...
make vet        # go vet ./...

Releasing

Push a version tag and GitHub Actions runs GoReleaser, which builds the archives, Linux packages, the multi-arch GHCR image, checksums, SBOMs, and a cosign signature:

git tag v0.1.0
git push --tags

The Homebrew and Scoop steps self-disable until their tokens exist, so the first release works with no extra secrets.
