How this service works
Machine-readable settlement service
Output
Returns a JSON object containing the Base64-encoded representation of the provided input string. The response schema is open-ended (additionalProperties: true), so the encoded result is returned as a field in the response body.
Example use cases
Encoding credentials for HTTP headers
“I need to base64 encode the string 'myusername:mysecretpassword' so I can include it in a Basic Auth HTTP header.”
Preparing binary data for JSON transport
“Take this raw string '\x00\x01\x02binary data here' and base64 encode it so I can safely embed it inside a JSON field.”
Encoding configuration values for deployment
“Base64 encode the string 'DATABASE_URL=postgres://user:pass@host:5432/db' so I can store it as a Kubernetes secret.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/encoding.base64-encode--base64-encodeWhen to prefer
Choose this endpoint when you need a quick, pay-per-use Base64 encoding operation without spinning up your own encoding library or infrastructure. It's suitable for agent workflows where encoding is an occasional step and the $0.001 USDC micro-payment cost is acceptable. Prefer local or free alternatives for high-volume bulk encoding.
Side effects
- Missing 'input' field in request body returns a validation error
- Empty string input may return an empty Base64 result or error
- Payment failure (x402 insufficient funds) blocks the request
- Malformed JSON request body causes a parse error
- Network timeout on Vercel cold start may cause latency spikes
