## 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 particle-pro-list-bill-text-versions-2e55bc5f
```

Example prompt: Can you pull up all the published text versions of bill ID HR1234 and give me the links to the PDF and HTML formats?

## When to prefer this

Use this endpoint when you need the actual document text or document links (PDF, XML, HTML) for a specific bill rather than metadata. Prefer this over the bills list endpoint when you already know the bill ID and need version history or downloadable formats. Ideal for legal research, legislative tracking, or compliance workflows that need authoritative source documents.

## Known failure modes

- Invalid or non-existent bill ID returns a 404 or empty result
- Bill has no published text versions yet (recently introduced)
- Rate limiting if too many requests are made in quick succession
- Network timeout or API downtime returns a 5xx error
