How this service works
Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.
Output
Returns a JSON object with the source URL, full transcript text, the Whisper model used (@cf/openai/whisper-large-v3-turbo), detected language code (e.g. 'en'), word count of the transcript, and audio duration in seconds.
Example use cases
Podcast clip transcription
“Transcribe the audio at https://cdn.example.com/podcast-clip.mp3 — I need the full text of what's spoken and the detected language.”
Voice memo to text
“I have a voice memo uploaded at https://storage.example.com/memo.ogg — can you convert it to text so I can read through it?”
Audio duration and word count check
“Can you check this audio file at https://media.example.com/speech.mp3 and tell me how long it is, how many words are spoken, and give me the transcript?”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call speech-to-text with no account setup, key management, or subscription, and you can pay $0.02 USDC per request on Base. Ideal for AI agents that occasionally need to transcribe short audio clips (under 5 MB) from public URLs without committing to a recurring API contract. Prefer over OpenAI Whisper API or AssemblyAI when you want zero-friction, crypto-native micro-payments via x402.
Side effects
- Audio file exceeds 5 MB limit — request rejected
- URL is not a valid http/https address — validation error
- Audio file URL is unreachable or returns a non-200 response — fetch error
- Unsupported audio format — transcription fails
- Payment in USDC on Base not completed — 402 Payment Required returned
- Very short or silent audio — may return empty or near-empty transcript
