## 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 moneytools-dex-token-price-eb3164cc
```

Example prompt: What's the current DEX price of WETH (0x4200000000000000000000000000000000000006) on Base in USDC, and what would the price impact be for a $5000 trade?

## When to prefer this

Use this endpoint when you need an executable, real-time DEX price for an ERC-20 token (not just a reference price), especially when you also need price impact for a specific trade size or want to verify price against DefiLlama. Prefer this over CoinGecko or CoinMarketCap lookups when you need the actual on-chain tradeable price rather than a market average. Best for DeFi automation, pre-trade analysis, or arbitrage detection across 7 supported EVM chains.

## Known failure modes

- Token address not found or unsupported on the specified chain — returns error with no charge
- Chain not supported — returns validation error
- Free tier (10/day) exhausted and no payment method provided — returns HTTP 402 with payment-required details
- Invalid ERC-20 address format — returns validation error
- DEX aggregator unable to find a route for the token — returns error with no charge
- Network connectivity issues with the DEX aggregator

## How this service works

Token price from DEX quotes: Executable-style price of any ERC-20 in USDC from DEX aggregator quotes (KyberSwap, quote only), price impact at a chosen size, route DEXes and deviation vs DefiLlama reference. Free tier 10/day; then $0.002 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.002 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object containing the executable token price in USDC derived from DEX aggregator quotes, price impact at the requested trade size (default $1000), the DEX route used, deviation from the DefiLlama reference price, and payment metadata (whether a charge was made, network, amount, transaction hash).
