How this service works
Tollex lets software agents buy APIs and tools under rules you set: it finds a capability that fits, checks your policy before anything is signed, pays with x402 in USDC on Base or USDG on Robinhood Chain, reconciles uncertain payments and returns a signed receipt.
Output
Returns the raw EVM bytecode (hex-encoded) deployed at the specified Ethereum-compatible address, along with a signed payment receipt confirming the USDC payment was processed via x402.
Example use cases
Verify contract deployment before integration
“I need to confirm that a smart contract is actually deployed at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — can you pull the on-chain bytecode so I know there's real code there?”
Audit contract code presence on-chain
“As part of my security review, can you retrieve the raw bytecode deployed at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 so I can check it matches the expected contract?”
Debug missing contract deployment
“Something seems wrong — can you check if there's any code deployed at 0xdAC17F958D2ee523a2206206994597C13D831ec7? I want to see the bytecode or confirm it's an empty address.”
Technical details
Endpoint
POSThttps://api.tollex.org/tools/chain_get_code?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to fetch the raw on-chain bytecode of a smart contract by address and are operating in an agent context that supports x402 micropayments in USDC. Prefer this over free public RPC calls when you need a managed, policy-checked, receipted transaction with reconciliation guarantees — especially in autonomous agent pipelines where auditability and payment provenance matter.
Side effects
- Invalid address format (not matching 0x + 40 hex chars) returns a validation error
- Address with no deployed code returns empty bytecode (EOA or undeployed address)
- Network or RPC errors may cause lookup failures
- Payment settlement failures if USDC balance is insufficient
- Uncertain payment states are reconciled and a receipt returned or error surfaced
