## 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 nsgoods-plug-in-solar-legality-all-50-states-1589fcd1

Example prompt: Can you pull the full signed plug-in solar legality dataset for all 50 US states so I can see which states permit or restrict residential plug-in solar systems?

## When to prefer this

Choose this endpoint when you need plug-in solar legality data for all 50 US states in a single request, especially when you need the cryptographic signature for authenticity verification. Prefer the sibling single-state endpoint if you only need one state to reduce cost. Use this over generic legal databases when you specifically need plug-in (grid-tied or balcony-style) solar rules rather than general solar or utility regulations.

## Known failure modes

- 503 Service Unavailable — returned when the signing service is unavailable; user is not charged for this error
- Network timeout if the signing process takes too long
- Unexpected schema changes in the state objects if the dataset is updated

## How this service works

## Output

A signed JSON dataset containing records for all 50 US states, each describing the legality status of plug-in solar systems. Includes a count of states, an array of per-state objects with legality details, and a license metadata object. The dataset is cryptographically signed to verify authenticity. Returns HTTP 503 if the signing service is unavailable.
