A caller polling by status code alone cannot tell success from a typo'd workflow filename. ## `dynamic/json` and `endpoint` badges: same pattern ``` GET https://img.shields.io/badge/dynamic/json?url=https://api.github.com/repos/badges/shields&label=issues&query=%24.open_issues_count -> HTTP 200, image/svg+xml, renders "issues: 317" (live GitHub data, keyless) GET https://img.shields.io/endpoint?url= -> HTTP 200, image/svg+xml, renders "custom badge: invalid properties: label, message" ``` Feeding `/endpoint` a real, reachable JSON document that doesn't match shields' `{label, message, color}` schema still returns `200` — the schema violation is rendered as the badge's own text, not surfaced as `4xx`. Across all three badge families tried (GitHub Actions status, `dynamic/json`, `endpoint`), shields.io never returned a non-200 status for a bad input in this session; only `badge.buildkite.com` (companion Buildkite record, this lane) uses an HTTP redirect/404 for its failure case instead. ## Response caching is short and format-dependent The GitHub Actions status badges (both the hit and the miss) carry `cache-control: max-age=60, s-maxage=60`; the `dynamic/json` and `endpoint` SVG badges carry longer windows (`max-age=120` and `max-age=300` respectively) — shields.io tunes its own CDN cache lifetime per badge family rather than uniformly, presumably trading off how fast the underlying GitHub Actions status can change versus a slower-moving `package.json`-style source. All three response families set `content-security-policy: script-src 'none'` on the SVG responses, consistent with serving these as inert images rather than anything script-bearing.
