1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Query repos.ecosyste.ms for repository metadata across GitHub, GitLab, Bitbucket, Codeberg, SourceHut and 1900+ other forges. Use when looking up a repo by URL, listing an owner's repos, fetching tags/releases/manifests, finding which repositories depend on a package, or generating an SBOM for a repo.

ecosyste.ms Repos API

Base URL: https://repos.ecosyste.ms/api/v1

All responses are JSON. No auth required. Set a User-Agent header identifying yourself. Unauthenticated clients share a rate limit and may see 429.

Full OpenAPI spec: https://repos.ecosyste.ms/docs/api/v1/openapi.yaml

Look up a repository

By URL or purl. Returns a single object (or 404).

curl -s 'https://repos.ecosyste.ms/api/v1/repositories/lookup?url=https://github.com/rails/rails'
curl -s 'https://repos.ecosyste.ms/api/v1/repositories/lookup?purl=pkg:github/ecosyste-ms/repos'

Useful fields: full_name, description, stargazers_count, forks_count, archived, fork, license, language, topics, default_branch, pushed_at, homepage, metadata.files (readme, license, changelog, funding paths), commit_stats.

Hosts

Host names are case sensitive: GitHub, gitlab.com, Bitbucket.org, codeberg.org, salsa.debian.org. List all with GET /hosts.

Repository full names containing / must be URL-encoded (%2F).

curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/rails%2Frails'
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/gitlab.com/repositories/gitlab-org%2Fgitlab'

Owners

curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/owners/rails'
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/owners/rails/repositories?sort=stargazers_count&order=desc'
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/owners/[email protected]'

Tags, releases, manifests, SBOM

curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/rails%2Frails/tags'
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/rails%2Frails/releases'

# parsed dependency manifests for the default branch
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/numpy%2Fnumpy/manifests'

# manifests at a specific tag
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/numpy%2Fnumpy/tags/v2.0.0/manifests'

# CycloneDX SBOM
curl -s 'https://repos.ecosyste.ms/api/v1/hosts/GitHub/repositories/numpy%2Fnumpy/sbom'

Package usage (dependent repositories)

Find repositories that depend on a package. Ecosystem here is the package manager name (npm, pypi, cargo, bundler, go, maven, nuget, composer), not the registry hostname.

# usage summary
curl -s 'https://repos.ecosyste.ms/api/v1/usage/npm/lodash'

# repos that depend on it
curl -s 'https://repos.ecosyste.ms/api/v1/usage/npm/lodash/dependent_repositories?per_page=20&sort=stargazers_count&order=desc'

# raw dependency edges (keyset pagination via ?after=ID)
curl -s 'https://repos.ecosyste.ms/api/v1/usage/npm/lodash/dependencies'

Topics

curl -s 'https://repos.ecosyste.ms/api/v1/topics/cli?fork=false&archived=false'

Pagination and filtering

List endpoints accept ?page=N&per_page=N. Repository lists accept fork=false, archived=false, created_after=ISO8601, updated_after=ISO8601, sort and order.

When to use

The user asks about a repository on any forge (not just GitHub)
Listing what dependencies a repo declares without cloning it
Finding which projects use a given package in the wild
Listing an organisation's repos sorted by stars or recency
Getting a CycloneDX SBOM for an arbitrary public repo
