# US House Clerk Lobbying Disclosures

The classic quarterly bulk-XML path no longer resolves:
```
curl -sS -o /dev/null -w "%{http_code}\n" \
  https://lobbyingdisclosure.house.gov/download/2026_3.zip
```
→ `404` (a real 4,720-byte HTML 404 page from that host, not a redirect or DNS failure — the
host is alive, the path convention is just gone).

`https://lobbyingdisclosure.house.gov/` itself still serves (200, guidance/PDF pages only) and
now points visitors at a Congress-run successor system:
```
href="https://lda.congress.gov/LDWebBeta/"
```
```
curl -sS -D - -o /dev/null https://lda.congress.gov/LDWebBeta/
```
→ `HTTP/2 403`, `cf-mitigated: challenge`, a Cloudflare managed-JS-challenge page (5,501
bytes) — a plain GET cannot reach the actual search/download system at all; it would need a
browser capable of solving the challenge.

A second linked host, `disclosurespreview.house.gov`, serves its homepage fine (200, 31,718
bytes, Azure-hosted per its CSP allowing `*.azurewebsites.net`) but has no discoverable
download links in the static HTML (the register browser is JS-rendered). Every guessed
sub-path on this host — `/api`, `/api/search`, `/api/v1`, and two guessed legacy ZIP filename
shapes — returned a uniform `500` rather than `404`:
```
curl -sS -o /dev/null -w "%{http_code}\n" https://disclosurespreview.house.gov/api/search
```
→ `500` (same for all 5 guessed paths). A catch-all 500 on any non-asset route is itself a
signal: this app has no real routing for those paths and errors rather than 404s, which would
mislead a client into retrying a dead path as if it were a transient server fault.

How observed: 2026-10-05T08:47Z–08:48Z, curl GET against the legacy ZIP path, the
`lobbyingdisclosure.house.gov` homepage, `lda.congress.gov/LDWebBeta/`, the
`disclosurespreview.house.gov` homepage, and 5 guessed sub-paths on the latter.
