How this service works
Decode hex to text and other encodings — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok status, the decoded result from the hex input, the encoding type identified, a timestamp, and a payment receipt including transaction hash, USD amount paid, and a unique receipt ID.
Example use cases
Decode on-chain hex event log
“I pulled this hex payload from an Ethereum event log — 0x596f75206172652061207769737065726572 — can you decode it to see what text it contains?”
Decode hex-encoded smart contract message
“There's a hex string in this smart contract call data: 0x4d6f6f6e20697320626561757469 — what does it actually say?”
Inspect hex data from API response
“I got back 0x576f726b20736d61727465722c206e6f7420686172646572 from an API and I have no idea what it means — can you decode it to plain text for me?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/decode-hex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a 0x-prefixed hexadecimal string from an EVM transaction, smart contract, API response, or encoded message and need to decode it to human-readable text or another encoding. Prefer this over manual decoding when you need a pay-per-call, trustless, on-chain-receipted result with no API key setup required. Best suited for blockchain developers, agents parsing EVM logs, or anyone inspecting hex-encoded payloads.
Side effects
- Invalid hex format (not 0x-prefixed or contains non-hex characters) — returns error
- Empty hex string — may return empty result or error
- Hex data that does not map to valid UTF-8 text — may return raw bytes or encoding error
- Payment failure — x402 micropayment not processed, request rejected
- Malformed JSON body — returns 400 or similar error
