## 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 coingecko-on-chain-categories-3870409d -d '<json body>'
```

Example prompt: Can you fetch the first page of on-chain token categories from CoinGecko so I can see how coins are classified on-chain?

## When to prefer this

Use this endpoint when you need a structured list of CoinGecko on-chain categories to classify, filter, or analyze tokens by their on-chain sector. Prefer this over off-chain category endpoints when working specifically with on-chain data taxonomy, DeFi protocols, or building dashboards that segment tokens by on-chain market segments.

## Known failure modes

- Invalid page number type returns a validation error
