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 transcription output (transcript text with optional per-word speaker labels), the model used, and the cost charged in micro-USD. When diarization is enabled, each word includes an integer speaker ID.
Example use cases
Podcast episode transcript with speakers
“Can you transcribe this podcast episode from https://example.com/podcast-ep42.mp3? I need to know which host said what, so turn on speaker diarization, and make sure any dollar amounts or statistics are formatted clearly.”
Meeting recording with multi-speaker labels
“Transcribe our team meeting from this audio file — https://example.com/team-call-jan15.wav — and mark each speaker so I can see who made which comments. Also normalize any dates or numbers we mentioned.”
Legal deposition audio to readable text
“Turn this recorded deposition into text for me from https://example.com/deposition-recording.mp3 — enable speaker identification so the transcript shows who asked each question and who answered, and format any monetary amounts properly.”

Endpoint
GEThttps://api.glianalabs.com/x402/grok-sttWhen to prefer
Choose this endpoint when you need audio transcription powered specifically by xAI's Grok STT model, want speaker diarization out of the box, need inverse text normalization for numbers and currencies, or require pay-per-call USDC billing with no API key or subscription. Prefer this over alternatives when operating in a crypto-native agent environment using x402/MPP payment protocols on Base, Tempo, or Solana.
