How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing the action performed ('encode' or 'decode'), the resulting string, a URL-safe variant of the output, and the input and output character lengths.
Example use cases
Encode API credentials for auth header
“I need to base64-encode the string 'myuser:mypassword' so I can use it in an HTTP Basic Authorization header — can you encode it for me?”
Decode a mystery base64 token
“I received this base64 string 'SGVsbG8gV29ybGQ=' and I need to know what it actually says — can you decode it back to plain text?”
Generate URL-safe base64 for a link
“Please base64-encode the string 'user_id=42&session=abc123' and give me the URL-safe version I can use in a query parameter.”
Technical details
Endpoint
GEThttps://klymax402.com/api/base64-codec/api/encodeWhen to prefer
Use this endpoint when your agent needs a quick, no-setup Base64 encode or decode operation without managing local libraries, or when running in an environment where you want a simple API call instead of executing code. Particularly useful within agent workflows that already use USDC x402 micropayments and need encoding as a utility step.
Side effects
- Missing 'data' parameter returns an error or empty result
- Invalid action value (not 'encode' or 'decode') may default to encode or return an error
- Non-UTF8 or binary data passed as string may cause garbled results
- Payment failure (insufficient USDC balance) returns HTTP 402
