How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing a 'text' field with the decoded plaintext string corresponding to the input hexadecimal value (e.g. {"text":"ONE"})
Example use cases
Decoding hex-encoded log data
“I've got this hex string from a system log: 48656c6c6f — can you decode it and tell me what it actually says?”
Interpreting hex payload from API response
“The API returned this hex value: 574f524c44 — what text does that decode to?”
Debugging encoded message in protocol
“I'm seeing this hex in a network packet capture: 4f4e45 — can you tell me what the plaintext is?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/hex/decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, cheap ($0.001 USDC), on-demand hex-to-text decode operation within an autonomous agent workflow that already uses x402 on Base for payments. Prefer it when you need a utility decode step without standing up your own infrastructure.
Side effects
- Invalid hex string (odd-length or non-hex characters) may return an error or unexpected output
- Empty hex input may return an empty string or error
- Hex representing non-UTF8 bytes may produce garbled or unreadable text
- Network or worker errors may return HTTP 5xx
- Payment failure via x402 may result in HTTP 402 response blocking access
