## Probes

```
GET https://httparchive.org/reports/state-of-the-web          (find the JS bundle)
GET https://raw.githubusercontent.com/HTTPArchive/httparchive.org/main/src/js/techreport/utils/constants.js
GET https://cdn.httparchive.org/v1/static/reports/numUrls.json
GET https://cdn.httparchive.org/v1/static/reports/numUrls.json   (Accept-Encoding: identity)
GET https://cdn.httparchive.org/v1/dates
```

## Observed

Guessing at `cdn.httparchive.org/reports/*.json` or `/almanac.json` all return a plain
`{"error":"Not Found"}` 404 — the real base path is **`/v1`**, confirmed only by reading
the site's own open-source JS (`src/js/techreport/utils/constants.js` on GitHub):
`const apiBase = 'https://cdn.httparchive.org/v1';`, then used in `timeseries.js` as
`${apiBase}/static/reports/${metric}.json`. Fetching
`https://cdn.httparchive.org/v1/static/reports/numUrls.json` returns HTTP 200 with
`content-type: application/json`, **`content-encoding: gzip`**, `content-length: 5350`
(the compressed size), `cache-control: public, max-age=3600, s-maxage=86400`. Re-sending
the same request with `Accept-Encoding: identity` gets the **identical** `content-length:
5350` and `content-encoding: gzip` headers back — the CDN does not honor a client's
request to skip compression; it serves gzip unconditionally. A client (or `curl -s`
without `--compressed`) that does not auto-decompress gets raw deflate bytes printed as
garbage, not valid JSON.

Decompressed, `numUrls.json` is a flat array of **554** `{timestamp, date, client,
urls}` objects spanning `date: "2010_11_15"` through `"2026_09_01"` (the full crawl
history, both desktop and mobile, in one file — no date-range parameter, no
pagination). `GET /v1/dates` returns `{"status":200,"dates":[...]}` listing every
monthly snapshot date string back to the archive's start, used by the front end to
populate date pickers.

## Conclusion

There is no documented public API reference for `cdn.httparchive.org/v1` on
httparchive.org itself; the only way to find the real metric-report URL shape is to read
the site's open-source frontend code. Once found, every metric file is the complete
historical timeseries in a single always-gzipped response, not a queryable or
date-sliced endpoint.

How observed: 2026-10-05T10:03:xx-10:05:28Z, GitHub raw/API reads plus five curl GETs
against cdn.httparchive.org (one explicitly requesting `Accept-Encoding: identity`).
