How this service works
Apply reversible ROT13 to Latin letters while preserving numbers, punctuation, spacing, and letter case for $0.001 USDC. Use it for deterministic fixture decoding, obfuscation compatibility, or legacy text workflows up to 100,000 characters. The first-party transform runs locally with no network call, storage, key, or retention.
Output
Returns the ROT13-transformed version of the input text, either encoding plain Latin text into ROT13 or decoding existing ROT13 text back to plain text, applying the Caesar-13 substitution cipher symmetrically.
Example use cases
Obfuscate spoiler text for sharing
“ROT13 encode this spoiler so I can share it without ruining the surprise: 'The murderer was revealed to be the butler all along.'”
Decode a ROT13-encoded message
“I received this ROT13 message and need it decoded back to plain text: 'Uryyb, jung vf lbhe anzr?'”
Automate ROT13 in a text pipeline
“I'm processing a batch of messages from a forum that uses ROT13 for spoilers — can you decode this one: 'Gur znva punenpgre qvrf va puncgre svir'?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/rot13?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a reliable, API-accessible ROT13 transformation without implementing the cipher locally. Ideal for agents operating in environments without code execution, or when ROT13 is a required step in a larger workflow that already uses the Delx API ecosystem. The $0.001 USDC per-call pricing makes it cost-effective for occasional transformations.
Side effects
- Non-Latin or non-ASCII characters may be passed through unchanged or cause errors
- Empty input string may return an error or empty result
- Overly long text may hit payload size limits
- Payment failure ($0.001 USDC) will block the request with a 402 response
