## Surface Transportation Board (stb.gov) — rail service data

**Probe 1** `GET https://www.stb.gov/data/` — `200`, 91,133 bytes, `text/html`.
Response headers include `Link: <https://www.stb.gov/wp-json/>; rel="https://api.w.org/"` and a
second `Link` pointing at `wp-json/wp/v2/pages/18996` (the page itself), the standard WordPress
self-discovery headers.

**Probe 2** `GET https://www.stb.gov/wp-json/wp/v2/pages/18996` — `401`:
```json
{"code":"rest_disabled","message":"The WordPress REST API has been disabled.","data":{"status":401}}
```
The site advertises its own REST API in every response's `Link` header, but the API itself is
turned off site-wide. An agent that follows the HATEOAS hint gets a clean, named refusal, not a
404 or a timeout.

**Probe 3** `GET https://www.stb.gov/reports-data/waybill/` — `200`, 107,539 bytes. No API here
either: the page lists one `.zip` per year of the **Public Use Waybill Sample** back to 1996
(`PublicUseWaybillSample2024.zip` is the current year), plus Uniform Railroad Costing System data.

**Probe 4** `HEAD https://www.stb.gov/wp-content/uploads/PublicUseWaybillSample2024.zip` — `200`,
`Content-Length: 68197449` (65 MiB), `Last-Modified: Thu, 30 Apr 2026 16:59:31 GMT`,
`Accept-Ranges: bytes`, `Access-Control-Allow-Origin: *`. A resumable, CORS-open static file —
the entire "API" surface for this dataset is "know the year, build the filename."

No discoverable JSON/XML feed for rail service metrics was found distinct from these yearly ZIPs
within this probe's budget.

Other response headers on the data page are worth noting for anyone fingerprinting this host:
`X-Hacker: Official Website of the United States Government` (a literal joke/self-identifying
header some .gov WAFs ship), `Access-Control-Allow-Origin: https://dcms-external.s3.amazonaws.com`
(a single, specific allowed origin rather than `*`), and `Content-Security-Policy:
frame-ancestors https://www.stb.gov https://dcms-external.s3.amazonaws.com
https://admin.govdelivery.com` — three named hosts that between them describe the site's whole
embed surface (self, an S3-backed external document viewer, and GovDelivery for email signup).
`Cache-Control: max-age=86400` with `X-Cache: MISS` shows the page itself is edge-cached for a
full day once warm.

How observed: 2026-10-05T10:55:30Z–10:56:03Z, `curl -D - -A "pwx-scout/1.0" --max-filesize 20000000 -m 60` against stb.gov (GET/HEAD only).

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.
