## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2s-io-6f9177c4
```

Example prompt: Pull the 50 most recently updated CRS bill summaries for House bills (type 'hr') in the 118th Congress, sorted by update date descending.

## When to prefer this

Use this endpoint when you need structured, CRS-authored bill summary text tied to specific legislative stages, especially for change-detection on tracked bills or building 'what did Congress just do' feeds. Prefer this over raw bill text endpoints when you want human-readable summaries rather than full bill text.

## Known failure modes

- Invalid bill type enum value returns 400 error
- Congress number out of range or not yet available returns empty result set
- fromDate/toDate in wrong format (not YYYY-MM-DD) returns 400
- Offset beyond available records returns empty array
- Rate limiting or payment failure returns 402

## How this service works

Stream the latest US Congressional bill summaries via Congress.gov. Each row is a CRS-authored summary attached to a specific version of a bill (Introduced, Reported to House, Engrossed in Senate, Public Law, etc.). Filter by congress + bill type. Returns the underlying bill metadata + summary text + version code + action date. Use this for change-detection on bills you care about, or to power agent-side "what did Congress just pass" feeds.

## Output

A paginated list of CRS-authored bill summary records, each containing the summary text, bill metadata (number, title, type), the version/stage code (e.g. Introduced, Reported to House, Public Law), and the action date when that summary version was created.
