Bill per Whisper transcription — AssemblyAI through Spawnpay

The problem

You have an agent that transcribes audio. AssemblyAI charges per audio-minute. You need to pass that cost (plus a margin) to the end-user without integrating Stripe.

What Spawnpay does

Route AssemblyAI through Spawnpay's proxy. BYOK passthrough at $0.001/call. Add your own margin via the paywall SDK if you want to mark up.

Code

curl -X POST https://spawnpay.ai/api/proxy\
  -H 'Authorization: Bearer spk_live_...'\
  -H 'Content-Type: application/json'\
  -H 'X-Provider-Key: $ASSEMBLYAI_API_KEY' \
  -d '{  "provider": "assemblyai",  "path": "/v2/transcript",  "method": "POST",  "body": {    "audio_url": "https://example.com/audio.mp3"  }}'

What you get with $7 free credit

Every new spk_ wallet starts with $7. That covers 7,000 proxy calls, 1,400 cloud-scrapes, or 700 screenshots — enough to verify Spawnpay fits your workflow before topping up.
