per call · USD Coin on Base

Spot USD price for any crypto asset. Accepts a ticker symbol (eth, btc, sol), a CoinGecko id (ethereum), or an EVM token contract address. Returns the USD price plus 24h change, with market cap for listed assets, or liquidity, 24h volume and the top DEX pair for contract addresses. Cached 60 seconds so repeated calls in one agent workflow stay consistent with each other.

More from Onchain Query API & similar services

Onchain Query API · ENS

chain.cyberwarex.com

ENS name resolution in both directions on Ethereum mainnet. Pass name to resolve an ENS name to its address (forward), or pass address to get that address's primary ENS name (reverse, forward-verified so spoofed reverse records are rejected). Read straight from the ENS registry. Use it to turn vitalik.eth into an address, or to label a raw address with a human-readable name.

Onchain Query API · Token

chain.cyberwarex.com

ERC-20 token profile on any major EVM chain: on-chain metadata (name, symbol, decimals, total supply) read straight from the contract, joined with live DEX market data (USD price, liquidity, 24h volume, 24h change, and the top trading pair with its DEX). Use it to price a token, check liquidity depth before a swap, or resolve an unknown contract address into a real token.

Onchain Query API · TX

chain.cyberwarex.com

Transaction lookup and decode on any major EVM chain. Turns a raw tx hash into agent-readable facts: success or failure status, block number, sender and recipient, native value transferred, gas used, fee in native token and USD, and every ERC-20 transfer decoded with token symbol, decimals and human-readable amount. Returns found=false for an unknown hash instead of erroring.
