Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-58db2e42
```

Example prompt: What are the current onchain DEX prices and 24-hour volume for these Base network token contracts: 0x4200000000000000000000000000000000000006 and 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913? Also include market cap and 24hr price change.

## When to prefer this

Use this endpoint when you need real-time onchain DEX prices for one or more specific ERC-20 token contract addresses on the Coinbase Base network, especially when the tokens may not be listed on centralized exchanges. Prefer this over CoinGecko's standard /simple/price endpoint when dealing with newly launched or DEX-only tokens identified by contract address rather than coin ID. Ideal for DeFi dashboards, portfolio trackers, or agents monitoring Base network token values.

## Known failure modes

- Invalid or unsupported contract address returns missing or null price data for that token
- Network not supported returns 404 or empty response
- Malformed contract address format causes 400 Bad Request
- Rate limiting or missing API key returns 401/429 error
- Token with no DEX liquidity on Base returns null price
- Truncated or overly long contract address list may cause request URI too large error

## How this service works

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

## Output

A JSON object mapping each queried contract address to its current onchain price in USD, along with optional fields such as 24-hour trading volume, market cap, 24-hour price change percentage, and total reserve in USD — all sourced from DEX liquidity pools on the Base network.
