// Overview

OpenSSF Scorecard REST API

The OpenSSF Scorecard REST API serves pre-calculated security-health scores for open-source repositories from Scorecard's public weekly scan, with per-check results such as branch protection, code review, pinned dependencies, signed releases and vulnerabilities. No key is needed. The README says "To query pre-calculated scores of OSS projects, use the REST API."

Coverage

Open-source repositories in Scorecard's public weekly scan. The README says weekly-scan results omit the CI-Tests, Contributors and Dependency-Update-Tool checks because of the API costs of running them at scale. Running the Scorecard CLI or GitHub Action on other repositories is a separate, local tool and not this source.

Verdict

A defensive signal for vetting open-source dependencies before you adopt them. Licence: CDLA-Permissive-2.0: the Scorecard README says "Data provided by the REST API is licensed under the CDLA Permissive 2.0." The Scorecard software itself is Apache-2.0. Scores are heuristics and change as checks are refined. Rate limits: Not stated as a number; the README says results are cached with a CDN. Signal Lab links only.
