How this service works
Robinhood Chain read-only eth_call: query any contract view function. Send { to, data, from? }.
Output
The raw ABI-encoded return value from the contract's view function, reflecting the current on-chain state at the time of the call. No transaction is broadcast; this is purely a read operation.
Example use cases
Check token balance on Robinhood Chain
“What's the USDC balance of wallet 0x1234...abcd on Robinhood Chain? Query the balanceOf method on the USDC contract at 0xToken...address.”
Read DeFi reserve state
“Fetch the current reserves from the Robinhood Chain liquidity pool contract at 0xPool...address by calling the getReserves view function.”
Verify NFT ownership onchain
“Check who owns token ID 42 on the Robinhood Chain NFT contract at 0xNFT...address — call the ownerOf function and return the result.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/rhchain/callWhen to prefer
Choose this endpoint when you need to read state from any smart contract on Robinhood Chain specifically (not Ethereum mainnet or other EVM chains). It is ideal for agents that need live on-chain data — balances, reserves, prices, ownership — without sending transactions or paying gas. Prefer it over generic EVM RPC endpoints when you want a pay-per-call model with no infrastructure setup.
Side effects
- Invalid contract address returns an error or empty result
- Malformed calldata (bad ABI encoding) causes a revert response
- Contract does not exist at the given address on Robinhood Chain
- View function reverts with an on-chain reason string
- Network congestion or RPC node unavailability causes a timeout
- Missing required 'to' or 'data' fields returns a 400-level error
