Morse code translator API: text to Morse and back

$0.01 per call · failed calls are never charged · no account or API key needed

Translate text to international Morse code (letters separated by spaces, words by /) or Morse code back to text; the direction is detected automatically or set with mode. Letters, digits and common punctuation are supported; anything else is reported, not guessed. Use for puzzles, radio practice and fun messages.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/text/morse?text=SOS%20help"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/text/morse?text=SOS%20help&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "mode": "encode",
  "result": "... --- ... / .... . .-.. .--.",
  "skipped": []
}
