How this service works
Pay-per-call API gateway on the x402 protocol (HTTP 402 + USDC on Base). This document covers the gateway's discovery and execution meta-endpoints. Individual provider APIs are reachable at /{api_slug}/{path} and described by GET /{api_slug}/metadata.
Output
Returns the upstream AssemblyAI API response body (transcript text, word-level timestamps, speaker diarization, confidence scores, etc.) along with gateway metadata including status, latency, cost, and the operation that was invoked.
Example use cases
Meeting recording transcription
“I have a recorded Zoom call at https://example.com/zoom-call.mp3 — can you transcribe it with speaker labels so I know who said what?”
Podcast episode to text
“Transcribe this podcast episode at https://cdn.mypodcast.com/ep42.mp3 and give me the full text so I can turn it into show notes.”
Voice memo to searchable text
“I left myself a voice memo at https://storage.myapp.com/memo-2024-01-15.wav — can you convert it to text using the AssemblyAI speech-to-text operation?”
Technical details
Endpoint
POSThttps://gateway.apiosk.com/assemblyai/executeWhen to prefer
Choose this endpoint when you need AssemblyAI's speech-to-text or audio intelligence capabilities and want to pay per call in USDC via the x402 protocol without managing an AssemblyAI API key subscription — ideal for agents that process audio intermittently and benefit from usage-based micropayment billing.
Side effects
- Invalid or inaccessible audio URL returns upstream 4xx error in result
- Unsupported audio format causes AssemblyAI rejection
- Insufficient USDC balance or x402 payment failure blocks the request
- Malformed operation selector returns gateway-level error
- Audio file too long or exceeds AssemblyAI limits triggers upstream rejection
- Network timeout to upstream AssemblyAI increases latency or fails
