How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns on-chain data from the queried smart contract, such as state variables, mapping values, or the result of a read-only (view/pure) function call — typically including the raw return value and any decoded output fields.
Example use cases
Check token balance across contracts
“I need to see how many tokens I hold in three different smart contracts on Base. Can you pull the balances for me from each contract?”
Verify NFT ownership and metadata
“Can you check what NFTs I own in this collection and pull back the metadata for each one from the smart contract?”
Monitor governance voting power
“Help me check my voting power in this DAO's governance contract and see what the current proposal thresholds are set to.”
Technical details
Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/crypto/contract/readWhen to prefer
Use this endpoint when you need to inspect the current state of a deployed smart contract without executing a transaction — e.g. checking balances, ownership, configuration parameters, or calling view functions. Prefer this over transaction endpoints when no state change is needed. Prefer this over block explorer scraping when you need structured, machine-readable output.
Side effects
- Invalid contract address returns an error or empty response
- Contract not deployed on the target network returns a revert or null
- Unsupported query format results in a parsing error
- Network congestion may cause timeout or delayed response
- Querying a write function (non-view) as a read may fail or return nothing
