geojs

IP geolocation and public-IP lookup via get.geojs.io.

geojs is a single pure-Go binary. It reads public GeoJS data over plain HTTPS, shapes it into clean records, and prints output that pipes into the rest of your tools. No API key, nothing to run alongside it.

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

Install

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

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

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

Usage

geojs lookup              # geo info for your own IP
geojs lookup 8.8.8.8     # geo info for a specific IP
geojs myip               # just your public IP address
geojs lookup 8.8.8.8 -o json   # as JSON, ready for jq
geojs --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.

Commands

Serve it

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

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

Use it as a resource-URI driver

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

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

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

ant get geojs://geoinfo/8.8.8.8   # fetch the record
ant url geojs://geoinfo/8.8.8.8   # the live https URL

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.
