# Morse Code Encoder/Decoder (ITU-R M.1677)

> Morse Code Encoder/Decoder (ITU-R M.1677) is a paid API for AI agents from text-ciphers.x402tookit.com, paid per call via x402, $0.02/call, status down (last checked 2026-10-24).

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.

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

## 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 morse-code-encoder-decoder-itu-r-m-1677-63e43196
```

Example prompt: Encode 'Hello World' into Morse code at 20 words per minute and give me the dot, dash, and gap timings in milliseconds.

## When to prefer this

Choose this endpoint when you need standards-compliant ITU-R M.1677 Morse code conversion with precise timing data (dot/dash/gap durations in ms and units) at a configurable speed. It is ideal for amateur radio applications, educational tools, or any scenario requiring both the Morse pattern and accurate transmission timing, as opposed to a simple dot-dash lookup table.

## Known failure modes

- Unsupported characters in input text (non-ASCII or characters without Morse equivalents) may be skipped or flagged in the 'unsupported' field
- Invalid WPM value outside 1–60 range may cause an error or be clamped to defaults
- Malformed Morse input (incorrect separator usage) when decoding may produce unexpected results
- Missing required 'text' query parameter will return an error

## How this service works

Morse code encode or decode (ITU-R M.1677) with dot/dash timing in units and milliseconds at a chosen words per minute.

## Output

Returns the encoded Morse code string (dots, dashes, spaces) or decoded plain text, along with full ITU-R M.1677 timing data including dot duration, dash duration, unit duration, letter gap, word gap, total units, and total milliseconds at the requested WPM speed.
