How this service works
Solana speech-to-text endpoint using x402 payments. Provide either a YouTube URL/ID or a direct audio file URL; the server downloads the audio, runs speech-to-text, and returns the transcript text. Pricing: 0.01 USDC per started minute of audio, computed from the estimated duration and charged upfront via x402. Default discovery price without a specific URL is 0.60 USDC as an upper-bound quote. When called without a specific URL, the endpoint returns a default discovery quote. Clients should re-run discovery with a concrete URL to get an exact quote based on the real video duration.
Output
Returns a plain text transcript of the spoken audio from the provided YouTube video or audio file URL. Payment is charged upfront at 0.01 USDC per started minute based on estimated audio duration. If no URL is provided, returns a default discovery quote of 0.60 USDC.
Example use cases
Example prompt
“Can you transcribe this YouTube video for me? Here's the URL: https://www.youtube.com/watch?v=dQw4w9WgXcQ — I need the full text transcript.”
Technical details
Endpoint
POSThttps://x402factory.ai/solana/sttWhen to prefer
Use this endpoint when you need to transcribe audio content from YouTube videos or direct audio URLs and are operating in a Solana/x402 payment environment. It handles the audio download and transcription pipeline end-to-end with per-minute USDC billing, making it ideal for agents that need programmatic pay-per-use transcription without a subscription.
Side effects
- Invalid or inaccessible YouTube URL/ID returns an error
- Audio file URL unreachable or unsupported format fails download
- Payment via x402 fails if wallet has insufficient USDC balance
- Very long videos may have higher upfront costs than expected
- Discovery call without a URL returns only a quote, not a transcript
