## 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 shovels-tags-permit-classification-tag-listing-a868a88b -d '<json body>'
```

Example prompt: Show me all the permit classification tags available in Shovels so I can figure out which tag values to use when filtering permit searches — return up to 100 tags per page.

## When to prefer this

Use this endpoint when you need to discover or enumerate all valid permit_tags filter values before constructing permit queries against Shovels data. This is a prerequisite lookup step — call it first to know what tag values are supported, then use those tags to filter actual permit searches.

## Known failure modes

- Invalid cursor string causes pagination error
- Size parameter outside 1-100 range returns validation error
- Unauthenticated or unpaid request (x402 payment required) returns 402 Payment Required
- Empty result set if no tags exist in the system
- Network timeout for large page sizes

## How this service works

Shovels Tags — list all available permit classification tags (and their descriptions) for use as `permit_tags` filters.

## Output

A paginated list of permit classification tag objects, each containing a tag identifier/name and a human-readable description of what kind of permits it classifies. Also includes a next_cursor value for fetching subsequent pages.
