# OpenSSF Scorecard REST API

## Coverage
Pre-computed Scorecard results for repositories the public pipeline has scanned (mostly high-traffic open source). `GET /projects/github.com/kubernetes/kubernetes` returns a full 18-check result, `score: 7.6` overall, dated `2026-09-28`.

## Access
`GET https://api.securityscorecards.dev/projects/github.com/{org}/{repo}` → `{date, repo: {name, commit}, scorecard: {version, commit}, score, checks: [{name, score, reason, details, documentation}]}`.

## Auth
None.

## Rate limits
None observed in headers on this probe.

## Freshness
`kubernetes/kubernetes` last scanned `2026-09-28`, 7 days before the probe.

## Known gaps
- `score: -1` on a check (observed today on `Packaging`, `Dangerous-Workflow`, `Token-Permissions`, `Signed-Releases`, `Branch-Protection` for this repo) means **the check could not run / is not applicable**, not "worst possible score (0)" — averaging or summing checks without excluding `-1` rows will understate the real score.
- A repository the pipeline has never scanned (probed with a nonexistent `github.com/{random}/{random}` path) is a bare `HTTP 404` with **no body at all** — there is no way to distinguish "never scanned" from "org/repo typo" from the response alone; both give the identical empty 404.
- There is no documented way to request an on-demand scan through this API — it only serves results the batch pipeline already produced.

## Probe log

```
$ curl -sS "https://api.securityscorecards.dev/projects/github.com/kubernetes/kubernetes" -o sc.json
$ python3 -c "
import json; d=json.load(open('sc.json'))
print(d['score'], d['date'])
print([c['name'] for c in d['checks'] if c['score']==-1])"
7.6 2026-09-28
['Packaging', 'Dangerous-Workflow', 'Token-Permissions', 'Signed-Releases', 'Branch-Protection']

$ curl -sS -D - -o /dev/null "https://api.securityscorecards.dev/projects/github.com/b-gutman/mojibake-does-not-exist-xyz"
HTTP/2 404
