## 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 gw2-game-worlds-population-status-0e32307c -d '<json body>'
```

Example prompt: Can you show me all the Guild Wars 2 game worlds and their current population status so I can pick one that isn't full?

## When to prefer this

Use this endpoint when you need a complete, up-to-date list of all Guild Wars 2 servers and their population statuses without needing to query individual worlds — ideal for helping players choose a server or for monitoring world population levels programmatically.

## Known failure modes

- Upstream GW2 API unavailability may return an error or stale data
- Payment failure returns 402 if USDC balance is insufficient
- Unexpected JSON structure if ArenaNet changes their API schema
