How this service works

One endpoint for 90+ generative AI models, live market data, SEC filings and identity APIs — image, video, music, speech, LLM chat, crypto and FX rates, DEX liquidity, gas, US company fundamentals and insider trades, document OCR and face matching. Pay per request in USDC on Tempo, Base, Solana, Algorand or BNB Chain with no signup, or top up a prepaid balance in rupiah.

Output

Returns a JSON object containing the model name used, an output object with the transcription text, and the cost charged in micro-USD for the call.

Example use cases

Example prompt

“Transcribe this audio recording for me — here's the file URL: https://example.com/meeting.mp3 — it's in English, and keep the output focused and deterministic (temperature 0.2).”

When to prefer

Choose this endpoint when you need keyless, pay-per-call audio transcription using GPT-4o's Whisper model without managing an OpenAI API key or subscription. Ideal for AI agents operating autonomously with a crypto wallet (USDC on Base, Tempo, or Solana) that need to transcribe audio on demand. Prefer over direct OpenAI API when you want x402 micropayment settlement and no prior signup.

Side effects

Unsupported audio format — only flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, webm are accepted
File too large — files must be ≤40MB; use /v1/media upload endpoint first for large files
Invalid data URI or inaccessible HTTPS URL — file must be publicly reachable
Payment failure — insufficient USDC balance on Tempo, Base, or Solana wallet
Language mismatch — prompt doesn't match audio language, reducing accuracy
Audio quality too low — heavy noise or distortion may yield poor transcription
