## 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 token-price-by-contract-address-base-ethereum-solana-a5997ed9
```

Example prompt: What's the current DexScreener price, liquidity, and 24-hour volume for the USDC token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Use this endpoint when you need real-time DEX price data for a specific token by its exact contract address or Solana mint on Base, Ethereum, or Solana. It is ideal when you need not just a price but also liquidity depth, trading volume, pair metadata, and DEX source — all in one call. Prefer this over CoinGecko-style endpoints when the token is a newer or smaller-cap asset that may only appear on DEXes, or when you need the specific pair address and quote token for downstream DeFi operations.

## Known failure modes

- Token contract address not found on DexScreener — returns found: false
- Invalid address format (not a valid EVM 0x address or Solana base58 mint) — rejected by schema validation
- Token exists on-chain but has no active DEX pair — found: false with no price data
- Unsupported chain specified — schema enforces enum of base/ethereum/solana
- Network or DexScreener API timeout — upstream latency error
- Payment of 0.001 USDC not provided or rejected — 402 Payment Required

## How this service works

Get a token price by contract address or mint on Base, Ethereum or Solana: DexScreener price, liquidity, volume and pair info

## Output

A JSON object containing the token's name, symbol, chain, contract address, current USD price, native-token price, pair address, quote token details, liquidity in USD, 24h volume in USD, 24h price change percent, market cap, FDV, DEX ID, price source (DexScreener), and a timestamp (as_of_ms). Also includes a boolean 'found' flag indicating whether a live pair was located.
