## 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 opendota-heroes-list-da13cd20 -d '<json body>'
```

Example prompt: Can you pull up the full list of all Dota 2 heroes along with their primary attributes, attack types, and roles?

## When to prefer this

Use this endpoint when you need a comprehensive, structured list of all Dota 2 heroes with their attributes, attack types, and roles without building or maintaining your own hero database. Ideal for hero-filtering, team composition tools, or any Dota 2 application needing a static hero reference dataset.

## Known failure modes

- Upstream OpenDota API unavailable — may return 502 or empty response
- Payment failure (x402) — call not authorized if USDC not provided
- Stale data if OpenDota hero list hasn't been refreshed after a Dota 2 patch
