## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vigenere-cipher-decoder-1a4803a3 -d '<json body>'
```

Example prompt: Can you decode this Vigenère cipher — the ciphertext is 'RIJVS UYVJN' and the key is 'SECRET'? Set decode to true.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call API to encode or decode text using the classical Vigenère polyalphabetic substitution cipher. Prefer it over general crypto libraries when you want a serverless, no-setup cipher utility accessible via HTTP. Not suitable for modern strong encryption — use only for classical cipher puzzles, educational purposes, or legacy compatibility.

## Known failure modes

- Missing or empty key returns an error or malformed result
- Non-alphabetic characters in text may be passed through unchanged or cause errors
- Invalid JSON body returns a 400-level HTTP error
- decode flag absent may default to encode or cause unexpected behavior
- Very long texts may time out or produce truncated results
