How this service works
keccak256 hash of a utf8 or hex string
Output
Returns the keccak256 hash (32-byte hex digest) of the provided UTF-8 or hex input string, suitable for use in Ethereum smart contracts, signature verification, or general cryptographic purposes.
Example use cases
Example prompt
“Can you compute the keccak256 hash of the UTF-8 string 'Hello, World!'?”
Technical details
Endpoint
GEThttps://propeller.rocks/keccak256When to prefer
Use this endpoint when you need a keccak256 hash of a string or hex value — especially in Ethereum/EVM/Solidity contexts where keccak256 is the canonical hash function. Prefer this over SHA-256 or other hashes when working with smart contracts, ABI encoding, event topic0 computation, or any Ethereum-native cryptographic operation.
Side effects
- Invalid or malformed hex input returns an error
- Empty input may return zero hash or error
- Network timeout for slow connections
- Payment failure if USDC balance insufficient
