## 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 govlaws-resolve-e9c08faf
```

Example prompt: Can you pull up the current full text of 12 CFR 1026.43 — I need to read the exact regulatory language for a compliance review.

## When to prefer this

Use this endpoint when you need to resolve a specific, known CFR or U.S. Code citation to its full authoritative text without requiring an API key — ideal for agents that can handle MPP microtransaction payment flows and need one-off citation lookups at $0.05 per call.

## Known failure modes

- Citation not found or malformed — returns error indicating unrecognized citation format
- Payment challenge not fulfilled — first call returns 402 with MPP payment challenge requiring resolution before content is returned
- Regulation has been removed or superseded — may return empty or redirect metadata
- Network timeout or upstream government source unavailable — service error response

## How this service works
