$0.05 per call · failed calls are never charged · no account needed: a card key or USDC

Summarize a voice note, meeting, call or podcast in one call: transcribes up to 60 minutes (MP3/WAV up to 25 MB; M4A, OGG or WebM up to 5 MB) by URL or upload, then returns a title, summary, key points, action items with owner and due date, open questions and the transcript, in the recording's language. Use for meeting notes, voicemail to CRM and call notes.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/transcribe/summary?url=https%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2F7%2F77%2FTofino_pronunciation.mp3"

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.
