Example prompt: Can you decode this Base64 string for me: 'SGVsbG8sIFdvcmxkIQ=='?

## When to prefer this

Use this endpoint when you need a quick, no-auth, pay-per-call Base64 decoding step inside an AI agent workflow — especially useful when handling encoded fields from API responses, JWT tokens, email headers, or configuration values without needing to spin up local compute or install libraries.

## Known failure modes

- Invalid Base64 string — malformed or incorrectly padded input returns an error
- Empty input field causes a bad request response
- Non-Base64 characters in the input string trigger a decoding error
- Binary output may not display cleanly if the original data was not UTF-8 text
