Output
Returns the current USD price for the specified token contract address on the given EVM chain, allowing agents to determine token value in US dollars.
Example use cases
Monitor DeFi token values across chains
“I need to track the USD prices for several tokens I'm holding across different EVM chains. Can you check the current price for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum, 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon, and 0x833589fCD6eDb6E08f4c7C32a07a298B865b0C06 on Base?”
Validate swap rates before execution
“Before I swap tokens on a decentralized exchange, I want to verify the fair market value. What's the current USD price for the token contract 0x7Fc66500c84A76Ad7e9c93437E434122A1R7A4Ee on Arbitrum and the one at 0x4e3FBD56CD56c3e312C14709618AEaA6A6A5eDDd on Optimism so I can check if the swap deal is reasonable?”
Track emerging DeFi protocol tokens
“I'm researching a new DeFi protocol and need to understand its tokenomics. Can you fetch the current USD price for their governance token at contract address 0x6982508145454Ce894A36eaf7838e2Bee38F8e45 on Ethereum? I want to see what the market is pricing it at right now.”
Technical details
Endpoint
POSThttps://evmapi.x402.fi/%7Bchain%7D/tokenPrice/%7BtokenAddress%7DWhen to prefer
Use this endpoint when you need to look up the real-time USD price of a specific ERC-20 or EVM-compatible token by its contract address on a named EVM chain. Prefer this over generic crypto price APIs when you have a contract address rather than a ticker symbol, or when dealing with newer/less-listed DeFi tokens not covered by centralized exchanges.
Side effects
- Invalid or unrecognized token contract address returns an error or null price
- Unsupported EVM chain identifier causes a bad request error
- Token not listed or lacking price data returns empty or error response
- Network/provider outage causes timeout or 5xx error
- Malformed address format returns validation error
