Hash & Encode
x402
Hash & Encode is a paid API for AI agents from bess-x402.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).
Computes MD5, SHA-1, SHA-256, SHA-512, SHA3-256, Keccak-256, BLAKE2b, and CRC32 hashes plus base64 and hex encodings of any text or binary input in a single call.

How this service works
MD5, SHA-1, SHA-256, SHA-512, SHA3-256, Keccak-256, BLAKE2b and CRC32 of a text or hex/base64 bytes, plus base64 and hex encodings, in one call. Use for integrity checks, IDs, signatures and Ethereum selectors.
Output
Returns a JSON object containing all eight hash digests (MD5, SHA-1, SHA-256, SHA-512, SHA3-256, Keccak-256, BLAKE2b, CRC32) and both base64 and hex encodings of the input, all computed in a single response.
Example use cases
Ethereum function selector generation
“What's the Keccak-256 hash of the UTF-8 string 'transfer(address,uint256)'? I need it to compute the 4-byte Ethereum function selector.”
Data integrity checksum for a file ID
“Give me the SHA-256 and MD5 hashes of the text 'invoice-2024-09-15-ACME' in UTF-8 — I'm using them as integrity fingerprints for a document ID system.”
Base64 and hex encoding of binary data
“I have some hex bytes '48656c6c6f20576f726c64' — can you decode them and give me all the standard hashes plus the base64 encoding?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/util/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple hash algorithms and encodings for the same input in a single call, especially for blockchain use cases (Keccak-256 for Ethereum selectors), integrity verification, or when you want to avoid making separate requests to different hashing utilities. It is particularly useful when both cryptographic hashes and encoding conversions are needed simultaneously.
Side effects
- Missing 'text' query parameter returns a validation error
- Invalid encoding value (not utf8, hex, or base64) returns a bad request error
- Malformed hex or base64 input string causes a decoding error
- Overly large input may result in a timeout or payload error
