How this service works
Machine-readable settlement service
Output
Returns a JSON object containing the operation name (e.g. 'base64-encode') and the result field holding the Base64-encoded string representation of the input.
Example use cases
Encode API credentials for HTTP auth
“Base64 encode my username:password string 'myuser:s3cr3tpass' so I can use it in an HTTP Basic Auth header.”
Encode JSON payload for embedding
“I need to encode this JSON string '{"key":"value","count":42}' into Base64 so I can safely embed it in a URL parameter.”
Prepare binary data string for transfer
“Take this raw data string '\x00\xFF\xAB\xCD\xEF' and Base64 encode it so I can safely transmit it over a text-only channel.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/f/encoding.base64-encodeWhen to prefer
Use this endpoint when you need a simple, on-demand Base64 encoding operation via a pay-per-call micropayment model (x402/USDC), especially in agent workflows where you want to avoid managing encoding libraries or dependencies, or where you need a verifiable, auditable external encoding step.
Side effects
- Missing required 'input' field returns a validation error
- Non-string input type may cause a 400 bad request
- Payment failure (402) if x402 payment header is missing or insufficient
- Very large input strings may hit size limits or timeout
- Malformed request body returns an error response
