## Services

- [Morse Code Encoder/Decoder (ITU-R M.1677)](https://www.zero.xyz/c/morse-code-encoder-decoder-itu-r-m-1677-63e43196/llms.txt): $0.02/call via x402. Encodes plain text to Morse code or decodes Morse code back to text, with precise dot/dash timing in units and milliseconds at a configurable words-per-minute speed.
- [NATO Phonetic Alphabet Encoder/Decoder](https://www.zero.xyz/c/nato-phonetic-alphabet-encoder-decoder-a669b211/llms.txt): $0.02/call via x402. Converts text to NATO phonetic alphabet words (e.g. 'Alfa, Bravo, Charlie') or decodes NATO phonetic words back to letters and digits.
- [Rail Fence (Zigzag) Cipher Encode/Decode](https://www.zero.xyz/c/rail-fence-zigzag-cipher-encode-decode-2038b374/llms.txt): $0.02/call via x402. Encodes or decodes text using the rail fence (zigzag) transposition cipher with a configurable number of rails (2–20).
- [Classic Shift Ciphers and Encodings (Caesar, ROT13, ROT47, ROT5, Atbash)](https://www.zero.xyz/c/classic-shift-ciphers-and-encodings-caesar-rot13-rot47-rot5-atbash-e7f3143f/llms.txt): $0.02/call via x402. Encodes or decodes text using classical shift and substitution ciphers — Caesar, ROT13, ROT47, ROT5, and Atbash — preserving case and punctuation.
- [A1Z26 and Polybius Square Number Ciphers](https://www.zero.xyz/c/a1z26-and-polybius-square-number-ciphers-e4b0d459/llms.txt): $0.02/call via x402. Encodes text to numbers or decodes numbers to text using A1Z26 (A=1, B=2…) or Polybius square cipher, with optional keyword square and ADFGX label support.
- [Playfair Cipher Encoder/Decoder](https://www.zero.xyz/c/playfair-cipher-encoder-decoder-4a7ec375/llms.txt): $0.02/call via x402. Encodes or decodes text using the Playfair cipher with a given keyword, returning the 5x5 key square and step-by-step digraph pairs.
- [Classic Ciphers and Encodings – Base Encoding/Decoding](https://www.zero.xyz/c/classic-ciphers-and-encodings-base-encoding-decoding-717e7071/llms.txt): $0.02/call via x402. Converts text or bytes to and from binary, octal, hex, decimal, Base32, Base58 (Bitcoin), Base64, and related encodings.
- [Classic Ciphers and Encodings: Frequency Analysis](https://www.zero.xyz/c/classic-ciphers-and-encodings-frequency-analysis-25ce7af8/llms.txt): $0.02/call via x402. Analyzes ciphertext to compute letter frequencies, index of coincidence, and most likely Caesar shift using English language statistics.
- [Grade 1 Braille Encoder/Decoder](https://www.zero.xyz/c/grade-1-braille-encoder-decoder-c0e5a100/llms.txt): $0.02/call via x402. Converts plain text to Unicode Grade 1 Braille cells (with number sign, capital sign, and dot annotations) and decodes Braille cells back to text.
- [Vigenere Cipher Encode/Decode](https://www.zero.xyz/c/vigenere-cipher-encode-decode-48bc6da5/llms.txt): $0.02/call via x402. Encodes or decodes text using the Vigenère cipher with a key, or estimates the key length of a ciphertext using the index of coincidence method.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
