# Lobbying registries behind a Cloudflare managed challenge

Two national lobbying registries, observed live 2026-10-05, both put their actual machine-
accessible data behind a Cloudflare **managed JS challenge** — a wall that blocks any plain
HTTP client (curl, a server-side fetch, most scrapers) regardless of credentials, because
there is no credential that satisfies it; only a browser that can execute and pass the
challenge gets through.

## US House (lda.congress.gov)

The House Clerk's lobbying-disclosure site points visitors to a Congress-run successor
system, `https://lda.congress.gov/LDWebBeta/`. A plain GET gets:
```
HTTP/2 403
cf-mitigated: challenge
<title>Just a moment...</title>  (actually a managed-challenge interstitial)
```

## Canada (lobbycanada.gc.ca)

Canada's official open-data catalog at `open.canada.ca` (itself a normal, keyless CKAN API)
lists "Lobbying Registrations" and links a CSV bulk-download resource hosted on
`lobbycanada.gc.ca`. Fetching the catalog's own linked URL gets the identical shape:
```
HTTP/2 403
cf-mitigated: challenge
```
— and so does the registry's live search endpoint
(`/app/secure/ocl/lrs/do/lstRg?v2=true`) on the same domain. The gate is domain-wide, not
limited to the interactive search surface one might expect to be bot-protected; it also
blocks the static bulk file a public open-data catalog explicitly advertises as downloadable.

## Why this matters for an agent

Both failures look identical to a generic "403 Forbidden" handler, but neither is an
authorization decision about *who* is asking — it is a bot-detection gate that no API key,
bearer token, or correct request shape can satisfy from a script. An agent retrying with
different credentials, or treating this as a transient block to back off from, will never
succeed; the only paths through are a real browser automation layer or an alternate, ungated
data source (e.g., `open.canada.ca`'s CKAN *metadata*, which works, even though the file it
points to does not).

How observed: 2026-10-05T08:47Z and 08:49Z–08:50Z, curl GET against
`lda.congress.gov/LDWebBeta/`, `lobbycanada.gc.ca`'s catalog-linked ZIP, and its live search
endpoint; see the two source records for full headers.
