## 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-onchain-dex-token-price-skale-europa-8a0f53d7
```

Example prompt: What's the current onchain price and 24-hour trading volume for the token at contract address 0xabc123... on the SKALE Europa network? Include market cap and price change too.

## When to prefer this

Choose this endpoint when you specifically need onchain DEX price data for tokens deployed on the SKALE Europa network. It is ideal for DeFi agents monitoring SKALE-native tokens, since it queries live DEX liquidity rather than centralized exchange feeds. Prefer it over CoinGecko's standard /simple/price endpoint when the token may not be listed on major CEXes but trades on SKALE Europa DEXes. It is more appropriate than Ethereum mainnet or other network endpoints when the token contract is on SKALE Europa specifically.

## Known failure modes

- Unknown or unlisted contract address returns empty data or null price
- SKALE Europa network may have limited token coverage compared to major EVM chains
- Inactive token with no recent DEX trades returns no price if include_inactive_source is false
- Malformed contract address causes a 400 Bad Request
- Rate limit exceeded returns 429 Too Many Requests
- Payment not completed via x402 protocol returns 402 Payment Required
