## 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 pro-api-coingecko-com-c6055aec
```

Example prompt: What's the current on-chain DEX price, 24-hour volume, and market cap for the Solana token at contract address So11111111111111111111111111111111111111112?

## When to prefer this

Use this endpoint when you need real-time on-chain DEX price data specifically for a Solana network token identified by its contract address, rather than a CoinGecko coin ID. Prefer this over the standard CoinGecko simple price endpoint when you need DEX-native pricing (not just exchange aggregates) and have a Solana contract address rather than a named coin slug.

## Known failure modes

- Invalid or non-existent Solana contract address returns empty or error response
- Token not listed on any Solana DEX returns no price data
- Payment failure (402) if x402 USDC payment is not provided or insufficient
- Rate limiting if API key quota is exceeded
- Network or upstream CoinGecko API outage returns 5xx error

## How this service works
