## 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-d968d172
```

Example prompt: What's the current onchain DEX price for the token at contract address 0x00c0943f0788cfd0782a893c0eefb42e154f15ae on the Base network, and can you also include the 24-hour volume and price change?

## When to prefer this

Use this endpoint when you need real-time onchain DEX price data specifically for the token at 0x00c0943f on the Coinbase Base network. Prefer this over CoinGecko's standard /simple/price endpoint when the token is only traded on DEXes and lacks a CoinGecko coin ID. Best for DeFi apps, portfolio trackers, or bots that need live Base-chain token prices directly from liquidity pool data.

## Known failure modes

- Token contract not found on Base — returns empty or null price data
- Network congestion causing stale or delayed price data
- Invalid contract address format — 400 Bad Request
- Payment not received or insufficient — 402 Payment Required
- Rate limit exceeded — 429 Too Many Requests
- Token has no active liquidity pools on Base — no price available

## How this service works

Query onchain DEX token price & market data based on the provided token contract addresses on a network.

## Output

Returns the current USD price of the specified token as traded on DEXes on the Base network, along with optional metrics: 24-hour trading volume, market capitalization, 24-hour price change percentage, and total reserve in USD. Data is sourced from onchain liquidity pools indexed by CoinGecko's GeckoTerminal.
