## 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 xrpl-data-desk-federal-register-filings-bdffefcd -d '<json body>'
```

Example prompt: Pull the last 60 days of proposed rules and notices from the Federal Register on stablecoins so I can see what regulators are working on.

## When to prefer this

Choose this endpoint when you need structured, filtered access to US Federal Register filings specifically scoped to financial and digital-asset regulatory topics, without having to scrape or parse the Federal Register website directly. Ideal for compliance monitoring, policy research, or regulatory change tracking in crypto and finance domains. Prefer this over generic web search when you need clean, structured regulatory data with consistent schema.

## Known failure modes

- Invalid 'days' value outside 1–90 range returns an error or default behavior
- Unrecognized 'type' or 'topic' enum values may return empty results or an error
- Upstream Federal Register data source unavailability causing stale or no results
- Payment failure via x402 protocol resulting in 402 response before data is returned
- Very broad queries returning large payloads that may be truncated
