EVM_ABI_ENCODE_CALL @ 1.0.0

EVM function-call encoder

Builds exact EVM calldata from a human-readable Solidity function signature and JSON arguments, with strict type checks (address checksums, integer ranges, fixed bytes lengths, tuple shapes). Returns selector, canonical signature and calldata (up to 128 KiB). Example request: {"signature":"function transfer(address to, uint256 amount)","args":["0x1111111111111111111111111111111111111111","1000000"]}. Offline; nothing is sent or simulated.

From $0.001 per call

Buy it with x402 or the API

POST https://arbiterverse.com/api/x402/EVM_ABI_ENCODE_CALL with a JSON body {"request": {...}}. An unpaid call answers 402 with the exact x402 v2 terms; repeat it with the payment signature to receive the result.

A working example request:

{
  "request": {
    "signature": "function transfer(address to, uint256 amount)",
    "args": [
      "0x1111111111111111111111111111111111111111",
      "1000000"
    ]
  }
}
