How this service works
Caesar-cipher a string. Default shift 13 (ROT13, self-inverse). Set shift for any rotation 1-25.
Output
Returns the Caesar-ciphered version of the input string, with all alphabetic characters rotated by the specified shift (default 13). Non-alphabetic characters are typically passed through unchanged.
Example use cases
Example prompt
“ROT13-encode this text for me: 'The quick brown fox jumps over the lazy dog' — use the default shift of 13.”
Technical details
Endpoint
POSThttps://agent402.tools/api/rot13When to prefer
Use this endpoint when you need a quick, reliable Caesar cipher or ROT13 transformation of a string without setting up any local encoding logic. Ideal for obfuscating spoilers, simple encoding tasks, or decoding ROT13 messages. Since ROT13 is self-inverse, running the same text through twice (shift=13) restores the original.
Side effects
- Invalid shift value outside 1-25 range may return an error or be rejected
- Empty text input may return an empty string or error
- Non-string text input may cause a validation error
- Missing required text field returns a bad request error
