One license by SPDX id, with full text
API · /licenses-api
Software Licenses API
The full SPDX License List as an API — all 729 software licenses with metadata and the complete license text for each. Look up any license by its SPDX id (e.g. MIT, Apache-2.0, GPL-3.0-only, MPL-2.0) and get the exact, canonical license text plus its name, reference URL, see-also links and standard header. Search or list licenses by name/id and filter by OSI-approved (Open Source Initiative), FSF-libre (Free Software Foundation) or deprecated status. Ideal for SBOM / license-compliance tooling, package managers, repository scanners, legal review, and open-source governance dashboards.

Launchpad API
Live project, people and release data from Launchpad, Canonical's open-source collaboration platform and the home of Ubuntu, via its public REST API. Launchpad is built around free-software projects, the teams that maintain them and the people in those teams. Get a project's profile — its title and summary, homepage, the licences it is released under, when it was registered and whether it tracks bugs, answers and translations on Launchpad. Resolve any Launchpad name to a person or a team, with its display name, whether it is a team, when it joined and its self-description. Pull a team's membership — the people and sub-teams that make up an open-source community. Get a project's released versions with their dates. Live, no key, nothing stored. Distinct from GitHub, GitLab, Codeberg and SourceForge forge APIs — this is Launchpad's project registry, its teams and its people. Perfect for open-source-directory, packaging, release-tracking and developer-community apps.

SourceForge API
Live project, release and download data from SourceForge, the original open-source software forge and download host. Unlike a git forge, SourceForge is built around distributing release binaries to the world, so its signature data is who downloads what, from where. Get a project's profile — its name, summary, status, creation date, homepage, the categories it is filed under and its developer count. Pull the download statistics for a date range — the total, the daily series and the breakdown by operating system. See where in the world a project is downloaded, the per-country download counts that no git forge exposes. Get the project's best current release with its file, version, size and date, plus the recommended download for Windows, macOS and Linux. Live, no key, nothing stored. Distinct from GitHub, GitLab and Codeberg git-forge APIs and from package registries — this is SourceForge's project directory and its global download analytics. Perfect for software-directory, release-tracking, download-analytics and developer apps.

Open Collective API
Live funding-transparency data from Open Collective, the platform where open-source projects, mutual-aid groups and communities raise and spend money in the open. Every collective shows its real finances: get a project's profile with its current balance, the total it has ever raised, its contributor and backer counts, currency and start date. Pull the people and organizations funding it, each with how much they have given in total and since when. Read the live money flow — every contribution and payment with its type, amount, description, counterparty and time. See what a collective pays out — each expense with its amount, payee, type and approval status. Live, no key, nothing stored. Distinct from GitHub, developer and social-profile APIs — this is the money side of a community: who funds it, what it holds, and how it spends. Perfect for open-source-funding, sponsorship, transparency, community and analytics apps.

Codeberg API
Live profile and repository data from Codeberg as an API — the community-run, Forgejo-powered git host and a leading open-source alternative to GitHub. Look up any user or organisation for their profile and social reach (followers, following, starred repositories, join date, location and website), open any repository for its stats (stars, forks, watchers, open issues, primary language, size and dates), or search Codeberg's repositories ranked by stars. The git-forge community layer for developer, social and dashboard apps. Live, no key, no cache. Distinct from GitHub and GitLab APIs and from package-registry APIs — this is the Codeberg platform's own community and project data.
