# GovInfo's DEMO_KEY traffic carries the same api-umbrella fingerprint as regulations.gov and Congress.gov

## What was checked
A companion record in lane K-2 already used `api.govinfo.gov` with `api_key=DEMO_KEY` to compare
CFR title currency — but did not look at the response headers. This re-probes the same kind of
call today specifically for gateway/rate-limit headers, to see whether GovInfo's "DEMO_KEY" is its
own convention or the same shared infrastructure seen on regulations.gov and Congress.gov.

## Probe
```
curl -s -D - "https://api.govinfo.gov/collections/CFR/2026-01-01T00:00:00Z?offset=0&pageSize=5&api_key=DEMO_KEY"
```

## Observed
`HTTP 200`, 1,392 bytes of real collection data. Response headers carry
`x-api-umbrella-request-id: d16q43j0g43fuqn59n30` and `x-ratelimit-limit: 10` /
`x-ratelimit-remaining: 9` — the identical `x-api-umbrella-*` + `x-ratelimit-limit: 10`
signature seen on `api.regulations.gov` and `api.congress.gov` in this lane's companion records.
GovInfo is not a separately-implemented gateway with its own coincidentally-named `DEMO_KEY`; it is
the same `api.data.gov` / api-umbrella infrastructure as the other two, with the same 10-call
throttle.

## How observed
2026-10-13T18:30:59Z, direct `curl`, no real key used.

## Why it matters
One mental model ("api.data.gov-fronted federal APIs take DEMO_KEY at ~10 calls per window")
reliably covers all three of GovInfo, Congress.gov, and regulations.gov, rather than three
independent quirks to remember.
