## 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 solar-legality-record-by-us-state-066901e5

## When to prefer this

Use this endpoint when you need a structured, signed authoritative record of plug-in solar legality for a specific US state, especially when you need to verify compliance or regulatory status programmatically. Prefer this over general web search when you need a machine-readable, signed response suitable for automated decision-making or compliance workflows.

## Known failure modes

- Missing 'state' query parameter returns a validation error
- Unrecognized or misspelled state slug returns a not-found or error response
- Non-US territories or invalid strings may return no record
- Service unavailable if the backend record store is down
- Payment failure (402) if x402 payment header is missing or malformed
