Verified steps
Send a GET request to https://api.securityscorecards.dev/projects/github.com/<owner>/<repo> to retrieve the most recent published Scorecard result for that repository.
Parse the JSON response's overall score plus the per-check array (each check has a name, score, and reason) to see which specific practices — e.g. Pinned-Dependencies, Token-Permissions, Branch-Protection — drove the score.
Note the response only covers repositories included in OpenSSF's periodic batch scan of tracked open-source projects — a repository outside that set will not have a published entry.
Cache or rate-limit calls in dependency-selection tooling (e.g. a CI gate evaluating a new dependency) rather than calling the API on every build, since the underlying data only refreshes on the batch scan's cadence, not in real time.
For repositories not covered by the public batch scan, run the scorecard CLI or GitHub Action directly against the repo instead of relying on the API.
Known gotchas
The API serves only pre-computed batch-scan results for repos in OpenSSF's tracked set — it cannot compute an on-demand score for an arbitrary repository, so don't treat a missing/empty response as 'score is zero.'
Score data reflects the last scheduled batch run, not the current HEAD, so it can lag recent commits.
The API is public and unauthenticated — don't assume paid-API SLA guarantees when wiring it into a CI gate; add fallback handling for outages or missing entries.
