## 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 g2-software-category-directory-c0cb6a33
```

Example prompt: Show me all G2 software categories related to 'security' — I need the category names, slugs, and their G2 URLs.

## When to prefer this

Use this endpoint when you need to discover, enumerate, or search G2's software category taxonomy — for example, to find the correct G2 category slug before navigating to a category page, to build a category map for market research, or to identify which G2 categories exist for a given software domain. It does not return product listings, reviews, or ratings — only category metadata.

## Known failure modes

- No categories match the filter query — returns empty categories array with count 0
- Limit parameter out of range (must be 1–500) — may return error or default behavior
- G2 public directory changes structure — category data may become stale
- Network timeout from upstream G2 data source

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a JSON object with the query string used, count of returned results, total matching results, source URL (g2.com/categories), a timestamp, and an array of category objects each containing the category name, slug, and full G2 URL.
