## Coverage
curl's auto-extracted Mozilla CA bundle — every root certificate in Mozilla's `certdata.txt` that carries an active trust bit, converted to PEM, maintained as the de facto default CA bundle for countless non-browser HTTP clients.

## Access
`GET https://curl.se/ca/cacert.pem` — keyless, `application/x-pem-file`. Observed 2026-10-05T11:48:35Z: 200, 188,900 bytes, SHA-256 `a41b5d356aea97a529fe27e0f7316d2f9d946d75927476cf9cf1b90637d00505`, **121** `BEGIN CERTIFICATE` blocks. File header states: `## Certificate data from Mozilla as of: Fri Sep 25 03:12:01 2026 GMT`.

## Auth
None.

## Rate limits
None documented; edge-cached via Varnish (`x-cache: HIT, HIT`, `x-cache-hits: 89927`). `Cache-Control: max-age=1800` (30 min), served through Fastly/Varnish with HTTP/2 and `alt-svc: h3`.

## Freshness
`Last-Modified: Fri, 25 Sep 2026 03:12:01 GMT` on this pull — the in-file "as of" comment and the HTTP `Last-Modified` header agree exactly, so either can be used to detect a refresh without downloading the body (conditional `If-Modified-Since` should work).

## Known gaps
- **121 certs here vs. 172 in Mozilla's own CCADB `IncludedCACertificateReportPEMCSV`** (same lane, different source) — the gap is curl's extraction script keeping only certs with an active server-auth/email trust bit at `certdata.txt` level, while CCADB's "included" report lists every CA in the program regardless of which trust bits are currently lit. Treat the two counts as answering different questions ("certs with a live trust bit" vs. "certs the program tracks"), not as disagreeing about the same fact.
- No ETag, only `Last-Modified`; no JSON/structured variant — PEM concatenation only, so programmatic per-cert metadata (issuer, validity) requires parsing the X.509 bytes yourself.
- Served via Fastly/Varnish rather than curl.se's own origin directly (`server: nginx/1.31.3` behind `via: 1.1 varnish, 1.1 varnish`); the high `x-cache-hits` count on a single pull confirms this is a heavily-shared edge object, not a per-request regeneration like CCADB's report in this same lane.
