Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 disclosure-categories-taxonomy-e5db4328
```

Example prompt: Pull the full list of 8-K disclosure categories from Massive's taxonomy, sorted by taxonomy version descending, so I can see every primary, secondary, and tertiary classification label available.

## When to prefer this

Use this endpoint when you need to understand or enumerate the classification schema for 8-K disclosures before querying the actual 8-K disclosures endpoint. It is the authoritative reference for valid category values, useful for building filters, validating labels, or exploring how disclosures are hierarchically organized. Prefer this over the 8-K disclosures endpoint when you need the taxonomy structure itself rather than actual filing data.

## Known failure modes

- Invalid filter value returns empty result set rather than an error
- Exceeding limit of 1000 returns a validation error
- Unknown sort column causes a 400 bad request
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Taxonomy version filter with no matching records returns an empty list

## Output

A paginated list of disclosure classification records, each containing a taxonomy version, primary category, secondary category, and tertiary category label. Results are sortable and filterable by any category level or taxonomy version, with up to 1000 records per response.
