Output
Returns the output of a smart contract read/view function — typically a value such as a token balance, address, boolean flag, integer, or structured data depending on the contract ABI and function called.
Example use cases
Check user token balance in wallet
“Can you look up how many USDC tokens are in my wallet at address 0x742d35Cc6634C0532925a3b844Bc0e7595f42bF1 on Ethereum? I need to verify my balance before making a transfer.”
Verify NFT ownership on-chain
“I want to check if my wallet owns the Bored Ape Yacht Club NFT with token ID 5555. Can you query the contract at 0xBC4CA0EdA7647A8aB7C2061c2E2ad38f53A1Efb0 and confirm if it's in my address?”
Monitor DeFi staking rewards accrual
“Check the pending rewards I've earned in the Aave protocol for my staked assets. Query the contract and tell me how much has accumulated since my last withdrawal.”
Technical details
Endpoint
POSThttps://prime-api-seven.vercel.app/api/crypto/contract/readWhen to prefer
Use this endpoint when you need to read on-chain state from a deployed smart contract without needing a Web3 node or RPC key, and want to pay per call in USDC with no API key management. Ideal for AI agents that need to query DeFi protocols, token contracts, or NFT metadata on-chain.
Side effects
- Invalid contract address returns an error or empty response
- Unsupported blockchain network returns a network error
- Incorrect function name or ABI mismatch causes call failure
- Node RPC timeout causes a slow or failed response
- Payment failure in USDC results in HTTP 402 before the call is made
