## How to call it through Zero

```sh
zero fetch --capability pro-api-coingecko-com-20fe2a2e
```

Example prompt: What's the current onchain USD price, 24h trading volume, market cap, and 24h price change for the token at contract 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on the Base network?

## When to prefer this

Use this endpoint when you need real-time onchain price data for the specific token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base, sourced from DEX liquidity pools rather than centralized exchange feeds. Prefer this over CoinGecko's off-chain /simple/price endpoint when you need DEX-native pricing, reserve data, or when the token is not listed on major centralized exchanges. Ideal for DeFi analytics, portfolio trackers, or arbitrage monitors focused on the Base ecosystem.

## Known failure modes

- Token contract not found or not indexed by CoinGecko — returns empty or null data
- Invalid contract address format — may return 400 or empty response
- Network mismatch (wrong chain) — no price data returned
- Payment failure (x402 flow) — 402 response if USDC payment not completed
- CoinGecko API unavailable or rate-limited — 5xx or 429 error
- Token is inactive on Base DEX — no recent price available if include_inactive_source is false

## How this service works

Returns the current price for a specified token contract on the Base network using CoinGecko's onchain pricing API.

## Output

Returns a JSON object keyed by the token contract address (lowercased) containing: current USD price as a string, 24-hour volume in USD, market cap in USD, total liquidity reserve in USD, and 24-hour price change percentage — all sourced from CoinGecko's onchain DEX aggregation.
