How this service works
Base64 and base64url encoding of text or bytes — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok:true, the encoding type ('encode-base64'), the base64 or base64url-encoded output string, and a payment receipt containing a transaction hash, USD amount, and receipt ID.
Example use cases
Encoding credentials for HTTP Basic Auth
“I need to base64-encode the string 'myuser:mypassword' so I can use it in an HTTP Authorization header.”
Encoding raw hex bytes from a transaction
“Can you base64-encode this hex data: 0xdeadbeefcafe0123 so I can embed it in a JSON payload?”
Preparing binary blob for API submission
“I have this hex-encoded binary blob 0x4865 6c6c6f and I need it as a base64 string to pass to another service.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/encode-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, deterministic base64 or base64url encoding of either a UTF-8 text string or raw hex-encoded bytes, especially in an agentic or automated pipeline where you are already working within the x402 payment protocol ecosystem and need a reliable, low-latency utility call.
Side effects
- Invalid hex string format (must start with 0x and contain valid hex characters)
- Text input exceeds 49152 character limit
- Malformed request body missing both hex and text params
- Payment failure causing 402 response
- Network timeout on the twin.unykorn.org host
