How this service works

Encode or decode text: base64, base64url, hex, URL (percent) encoding and HTML escaping.

Output

A JSON object containing the operation name (op) and the resulting transformed string (result), e.g. {"op":"base64-encode","result":"aGVsbG8gd29ybGQ="}.

Example use cases

Encoding payload for API auth

“I need to base64-encode my API credentials string 'myuser:mypassword' so I can put it in an Authorization header.”

Decoding a received JWT claim

“Can you base64url-decode this string for me: 'eyJzdWIiOiIxMjM0NTY3ODkwIn0' — I want to see what's inside?”

Percent-encoding a URL query parameter

“I need to URL-encode this text so it's safe to use as a query parameter: 'hello world & goodbye world!'”

When to prefer

Choose this endpoint when you need a fast, reliable, pay-per-call text encoding or decoding operation without setting up any libraries or runtime — especially for base64, base64url (JWT-safe), hex, percent-encoding, or HTML escaping. Ideal for agents that need to encode/decode strings on the fly within a workflow without depending on execution environments.

Side effects

Input text exceeds 1 MB limit — request rejected
Invalid or missing 'op' enum value — validation error
Malformed base64/hex/URL input when decoding — error or garbled output
Missing 'text' field in request body — validation error
