`GET https://devstats.cncf.io/api/v1`
`GET https://devstats.cncf.io/api`
`GET https://<project>.devstats.cncf.io/`

## Probe 1 — the aggregate API refuses GET with a structured error
`GET /api/v1` answers `HTTP 200` (not 405) with `application/json` body
`{"error":"API 'unknown': EOF"}` — the handler is real and JSON-aware, but expects a POST
body naming an API call (devstats' documented JSON-RPC-style contract: `{"api":"...",
"payload":{...}}`); an empty GET body parses as EOF before it can even reject an unknown API
name. `GET /api` (no trailing slash) answers `301` to `/api/` (text/html, 162 bytes) — a
plain path-normalization redirect, not API content. **Not probed further with a POST body**
per this lane's GET/HEAD-only rule — recorded as POST-only, not asserted.

## Probe 2 — per-project dashboards are plain public HTML, no auth
Each CNCF project gets its own Grafana-backed subdomain, e.g.
`aerakimesh.devstats.cncf.io/` (named from CLOMonitor's `devstats_url` field, see the
companion record) — `HTTP 200 text/html`, reachable with no authentication and no API key,
a conventional Grafana dashboard UI rather than a JSON API.

## Known gaps
The actual list of valid `api` names for the JSON-RPC body is not documented at this path;
it would require either reading devstats' source or a POST probe this lane does not send.
This record asserts only the GET-refusal shape and the existence/reachability of per-project
dashboards — not any claim about what a correctly-formed POST would return.

## Auth
None observed on the dashboard subdomains for anonymous read access; the aggregate API's
auth model (if any, for a well-formed POST) is unknown from this probe since no POST was
sent.

## Rate limits
Not probed; a single GET per path in this session, no 429s or rate-limit headers seen.

## How observed
How observed: 2026-10-05T11:35:34Z-11:35:42Z, `curl` GET against `devstats.cncf.io/api`,
`/api/v1`, and a live project subdomain; response bodies and status codes read directly, no
non-GET request made to this host.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
