## 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 polymarketeer-vercel-app-e289e130 -d '<json body>'
```

Example prompt: Show me all the available tags and categories on Polymarket, including how many events are in each one.

## When to prefer this

Use this endpoint when you need to discover what topic categories or tags exist on Polymarket before filtering or browsing events — ideal for building category pickers, understanding taxonomy, or dynamically constructing event search queries. Prefer this over the event search endpoint when you need the full category list rather than specific events.

## Known failure modes

- Payment failure (insufficient USDC balance) returns 402
- Polymarket API unavailable returns 503 or error object
- Invalid request body format returns 400
- Network timeout if Polymarket upstream is slow
