Endpoint
POSThttps://deepgram.x402.paysponge.com/v1/speakWhen to prefer
Use this endpoint when you need pay-per-call text-to-speech synthesis powered by Deepgram and want to pay via USDC micropayments using the x402 protocol — ideal for agents that need on-demand TTS without a subscription, or for workflows integrating with the PaySponge/x402 payment layer.
Side effects
- Empty or missing text field returns a 400 error
- Payment failure via x402 protocol results in 402 Payment Required response
- Text that is too long may be rejected or truncated depending on model limits
- Network timeout for very long synthesis tasks
- Unsupported characters or languages in text may yield degraded or empty audio
