How this service works
Encode/decode hex for $0.002 USDC for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the converted value — either a plain-text string decoded from the provided hex input, or a hexadecimal string encoded from the provided raw text/binary input.
Example use cases
Decode hex payload from API response
“I got this hex-encoded response from another API: 4a736f6e20726f636b73 — can you decode it to plain text for me?”
Encode config value in hex for storage
“I need to store the string 'api_secret_v2' as a hex-encoded value — can you hex-encode it for me?”
Verify hex encoding in debugging session
“I'm debugging a message pipeline and need to check if this value 576f726b73 correctly encodes the word 'Works' — can you convert it and confirm?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/hex-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a quick, paid-per-call hex encode/decode operation without standing up its own transformation logic, especially in x402-native payment workflows where micro-billing per conversion is acceptable.
Side effects
- Invalid hex string (odd-length or non-hex characters) returns an error
- Missing or malformed input body returns 400
- Payment not provided or insufficient USDC returns 402
- Ambiguous encoding direction if not specified may produce unexpected output
