Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 federal-register-crypto-digital-asset-regulatory-changes-feed-ce34ec38
```

Example prompt: Pull all Federal Register crypto and digital asset regulatory changes since January 1, 2025, but only show me the ones with a compliance impact score of at least 7 — I want the titles, effective dates, and source links.

## When to prefer this

Use this endpoint when you need real-time or recent Federal Register regulatory intelligence specifically scoped to cryptocurrency and digital assets, with compliance prioritization via significance scoring. Prefer this over general Federal Register search when you want pre-filtered crypto-relevant rules and need to integrate compliance impact scores directly into workflows or alerts. Use the since parameter for incremental polling to detect net-new regulatory changes since your last check.

## Known failure modes

- Invalid 'since' format (non-ISO-8601) returns a 400 error
- min_significance outside 1–10 range returns a 400 error
- limit outside 1–500 range returns a 400 validation error
- Missing or invalid x402 payment header returns a 402 Payment Required
- No changes found in the requested window returns an empty changes array with count 0
- Upstream Federal Register data source temporarily unavailable returns a 503 or empty result

## How this service works

Federal Register final & proposed rules affecting crypto & digital assets since a timestamp — covering digital asset, cryptocurrency, stablecoin, virtual currency, crypto — each scored 1-10 for compliance impact, with effective dates and primary-source links.

## Output

A JSON array of regulatory change objects, each containing: title, rule type (final/proposed), a 1–10 compliance significance score, a plain-language summary, effective date (if available), a primary-source Federal Register URL, detection timestamp, and a unique entityId for further detail lookups. Also returns a total count and source identifier.
