## When to prefer this

Choose this endpoint when you need live on-chain DEX prices for tokens that may not be listed on CoinGecko or CoinMarketCap, especially long-tail, newly launched, or obscure DeFi tokens. It supports up to 30 contract addresses per call across 8 chains, making it efficient for batch portfolio pricing. Prefer it over CoinGecko-based endpoints when dealing with contract-address-level lookups rather than ticker symbols.

## Known failure modes

- Invalid or non-existent contract address returns no price data (no charge applied)
- Unsupported network name returns validation error
- Exceeding 30 addresses per call may result in truncation or error
- Token with no DEX liquidity or trading activity returns empty price data
- Solana mint address provided on EVM network param (or vice versa) returns no match

## How this service works

Use to price tokens by contract address, including long-tail tokens with no CoinGecko listing. Live DEX price, 24h change, volume, liquidity and market cap for up to 30 tokens per call on ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana. One flat price per call; not charged if no address has a price.

## Output

Returns a JSON object per requested token address containing: live DEX price (in USD), 24-hour price change percentage, 24-hour trading volume, liquidity depth, market cap, and associated token metadata. If no address has a retrievable price, the call is not charged.
