How this service works
Encode UTF-8 text as standard Base64 or Base64URL
Output
Returns a Base64 or Base64URL-encoded string representation of the input UTF-8 text. When url_safe is true, the output uses the URL-safe alphabet (- and _ instead of + and /) and omits padding characters (=).
Example use cases
Encode API credentials for HTTP Basic Auth
“I need to encode the string 'myuser:mypassword' as standard Base64 so I can put it in an Authorization header for a Basic Auth request.”
Prepare JWT payload for URL embedding
“Can you base64url-encode this JSON string '{"sub":"user123","role":"admin"}' using the URL-safe unpadded format so I can use it as part of a JWT or URL parameter?”
Encode binary config data as base64 for storage
“Take this text 'apiKey=abc123&secret=xyz789' and encode it as standard Base64 so I can store it safely in a config field that expects base64 values.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/base64/encode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a lightweight, pay-per-call Base64 or Base64URL encoding utility without managing local encoding libraries or infrastructure. Ideal for agents operating in environments where running code is not possible and a simple HTTP call suffices. The url_safe option makes it directly useful for JWT construction, URL parameter encoding, and data URI preparation.
Side effects
- Non-UTF-8 or malformed text input may cause a 400 error
- Missing required 'text' field returns validation error
- Network or worker availability issues may cause 5xx responses
- Payment failure or insufficient funds returns 402 status
