Base 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 audio duration.
