Facts

Website: ecosyste.ms
Price: Free tier · from $200/mo
Free trial: Not stated
API access limits: Anonymous users can access services; identifying with a user agent or API key gives a higher rate limit.
API request pools: The common pool may have less consistent response times, especially during peak periods, because polite requests receive priority.
API specification: The APIs follow OpenAPI 3.0.1 and provide machine-readable specifications and interactive documentation.
Commercial services: Commercial customers can request data exports, custom access, and direct support; academic institutions and charitable organisations may request discounted access.
Dependency tools: The Dependency Parser resolves a repository's full dependency tree, while the Dependency Resolver resolves a package's full dependency tree.
Intended users: The maker describes its audience as developers, researchers, and policymakers.
Licensing: The documentation states that the code is licensed under AGPL and the data under Creative Commons Attribution Sharealike; commercial licenses with less restrictive terms are available on request.
Maker and hosting: ecosyste.ms is a non-profit initiative hosted by Open Source Collective.
Other tools: Digest checks package or repository integrity, Archives inspects contents, Diff compares contents, and Summary produces project overviews.
