## 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 rubric-protocol-regwatch-feed-941b8e1a
```

Example prompt: Pull the latest RegWatch feed so I can see any new AI regulatory changes, upcoming effective dates, and open comment deadlines across all jurisdictions — I need the attested version from Rubric Protocol.

## When to prefer this

Choose this endpoint when you need a curated, attested, machine-readable stream of AI regulatory changes across multiple jurisdictions, especially when cryptographic provenance or audit trails matter for compliance purposes. Prefer it over raw government data sources or general news feeds when you need structured fields (effective dates, comment deadlines, instrument type) and verifiable attestation rather than unstructured text.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Feed temporarily unavailable — returns 5xx server error
- No new regulatory items in the feed — returns empty result set
- Malformed request — returns 400 Bad Request
