How this service works

Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.

Output

Returns a JSON object containing the Base64-encoded or decoded result string, the number of bytes in the result, the operation performed (encode/decode), and whether URL-safe mode was used.

Example use cases

Encoding API credentials for auth header

“I need to base64 encode the string 'myuser:mypassword' so I can use it in a Basic Auth header — standard base64, not URL-safe.”

Decoding a base64 payload from an API response

“I got this base64 string back from an API: 'eyJzdWIiOiIxMjM0NTY3ODkwIn0=' — can you decode it to plain text for me?”

Preparing URL-safe base64 for a web token

“Encode the string 'agent-token-xyz-123' as URL-safe base64 so I can safely embed it in a URL or JWT claim.”

When to prefer

Use this endpoint when you need a quick, keyless Base64 encode or decode operation within an agent workflow that already uses x402 micropayment infrastructure — especially useful when you want URL-safe vs standard base64 control and a byte count returned alongside the result.

Side effects

Missing required 'data' query parameter returns an error
Invalid operation enum value (not 'encode' or 'decode') causes a validation error
Malformed or non-base64 input when decoding may return an error or garbage output
Payment failure via MPP/x402 results in 402 status before processing occurs
