How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object with the mode used ('encode' or 'decode') and the output string — either the hex-encoded version of the input text, or the decoded plain text from a hex string.
Example use cases
Debug hex protocol payload
“I'm looking at a network packet and see this hex string '48656c6c6f' — can you decode it to readable text for me?”
Encode secret key for config file
“Encode the string 'my-secret-token-abc123' as hex so I can safely embed it in my config file.”
Verify hex encoding roundtrip
“Take the text 'GeekVault API test' and encode it to hex, so I can verify my own decoder is working correctly.”

Endpoint
GEThttps://api.geekvault.dev/dev-tools/v1/hex?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-signup hex encode or decode operation and are already operating in the x402/USDC-on-Base payment ecosystem. Ideal for AI agents that need lightweight dev-utility conversions without managing API keys or subscriptions.
Side effects
- Missing required 'input' field returns an error
- Invalid hex string when decoding (odd-length or non-hex characters) may return an error or garbage output
- Payment failure via x402 if insufficient USDC balance on Base
