How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns the data output from the smart contract's queried method or state variable, such as numeric values, addresses, booleans, or structured data representing the on-chain state at the time of the call.
Example use cases
Check ERC20 token total supply
“What is the total supply of the USDC token on Base? The contract address is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — read the totalSupply from the contract.”
Verify NFT contract ownership
“Check who owns token ID 42 on this NFT contract at 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum — read the ownerOf method from the contract.”
Read DeFi protocol reserve data
“Read the getReserves function from the Uniswap V2 pair contract at 0xB4e16d0168e52d35CaCD2c6185b44281Ec28C9Dc on Ethereum so I can see the current liquidity pool reserves.”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/crypto/contract/readWhen to prefer
Choose this endpoint when you need to read (not write) data from a deployed smart contract without setting up your own blockchain node or RPC infrastructure. Ideal for fetching token balances, contract state variables, allowances, ownership, or any view/pure function output. Prefer this over direct RPC calls when you want a simple pay-per-call model with no API key setup.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Querying a method that doesn't exist on the contract returns a revert or null
- Network unavailable or RPC node issues cause timeout
- Malformed query string results in parsing error
- Contract deployed on a different chain than expected returns no data
