How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object containing the mode used ('encode' or 'decode') and the output string — either the Base64-encoded version of the input or the decoded plain-text result.
Example use cases
Encode credentials for HTTP Basic Auth
“Base64-encode the string 'myusername:mypassword' so I can use it in an HTTP Authorization header.”
Decode a Base64 payload from an API response
“Decode this Base64 string for me: 'SGVsbG8sIFdvcmxkIQ==' — I want to see the original plain text.”
Encode a JSON config snippet for embedding
“Can you Base64-encode this JSON string: '{"api_key":"abc123","env":"production"}' so I can safely embed it in a config file?”
Technical details
Endpoint
GEThttps://api.geekvault.dev/dev-tools/v1/base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-signup Base64 encode or decode operation and are already operating in an x402/USDC payment context. Useful when your agent runtime doesn't have a native Base64 library or you need a consistent remote utility call for encoding/decoding without managing API keys or subscriptions.
Side effects
- Missing 'input' parameter returns a 400-style error
- Invalid Base64 string provided in decode mode may return an error or garbled output
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Invalid mode value (not 'encode' or 'decode') may default to encode or return an error
