## 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-e32c4700
```

Example prompt: Pull up the full details for Senate hearing jacket number 117890 from the 118th Congress, and also list any other Senate hearings from January 2024 through March 2024.

## When to prefer this

Use this endpoint when you need authoritative, primary-source US Congressional hearing data including committee testimony, transcripts, and recordings — especially for policy research, legislative oversight analysis, or finding specific hearings by jacket number. Prefer over general web search when structured, filterable government data is needed.

## Known failure modes

- Invalid or nonexistent jacket number returns 404 or empty result
- Invalid congress number returns error
- Chamber value not one of 'house' or 'senate' causes validation failure
- Date range with invalid format (non-YYYY-MM-DD) causes parsing error
- Offset beyond available records returns empty list
- Payment failure (x402) if USDC not provided

## How this service works

Look up or list US Congressional hearings via Congress.gov. Pass congress + chamber + jacketNumber to fetch a single hearing with full detail (title, dates, committee, transcripts/recordings if available). Or filter list by congress + chamber, with optional date range. Hearings cover committee testimony from the executive branch, subject experts, and stakeholders — primary-source material for oversight + policy research.

## Output

Returns a single hearing record (when jacket number is provided) with full detail including title, dates, committee, and available transcripts or recordings; or a paginated list of hearings filtered by congress, chamber, and optional date range.
