How this service works
minia2a service: x402-abi-encode
Output
Returns ABI-encoded bytes (typically as a hex string) representing the encoded calldata or parameters, suitable for use in Ethereum smart contract interactions or raw transaction construction.
Example use cases
Encode ERC-20 transfer calldata
“I need to ABI encode a call to the `transfer` function with input types `address,uint256` so I can construct raw calldata for an ERC-20 token transfer.”
Prepare smart contract constructor args
“Can you ABI encode the constructor arguments for my smart contract? The method is the constructor, and the parameter types are `string,uint256,address`.”
Build encoded payload for multicall
“I'm building a multicall transaction and need to ABI encode each sub-call. Encode a call to `approve` with bodyType `address,uint256` and output type `bool`.”
Technical details
Endpoint
GEThttps://minia2a.uk/x402/abi-encodeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use ABI encoding service without running a local Ethereum library. It is suitable for agents that occasionally need to encode smart contract calldata on demand, especially in serverless or resource-constrained environments where importing ethers.js or web3 is impractical.
Side effects
- Invalid or unsupported Solidity type string causes encoding failure
- Mismatched parameter count vs type definitions returns an error
- Malformed queryParams object leads to a 400 bad request
- Unsupported ABI version or method signature format
- Network or service timeout returns a 5xx error
