## 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 us-federal-bill-lookup-f6b9ab88
```

Example prompt: Can you pull up the full details for HR 3076 from the 118th Congress — I want to see the sponsor, cosponsors, which committees reviewed it, and where it stands in the legislative process?

## When to prefer this

Use this endpoint when you need comprehensive structured data on a specific US federal bill — including its full legislative history and lifecycle stage — rather than just a summary. Ideal for legislative tracking, policy research, or compliance workflows that require authoritative Congress.gov data with computed stage labels rather than raw XML parsing from GovInfo directly.

## Known failure modes

- Invalid or unrecognized bill ID format returns an error
- Bill not found for the given congress number and bill type/number combination
- Partial data if the bill is very new and not yet fully indexed
- Missing optional fields (cosponsors, committees) for very early-stage bills

## How this service works

Look up one US federal bill by id: title, sponsor, cosponsors, committees, policy area, full action history and computed lifecycle stages (introduced to enacted). Source: Congress.gov + GovInfo, public-domain.

## Output

A structured record for the requested US federal bill including its official title, primary sponsor, list of cosponsors, committees of jurisdiction, policy area classification, a chronological full action history, and computed lifecycle stages (e.g. introduced, referred, passed House, passed Senate, enacted) derived from Congress.gov and GovInfo data.
