How this service works
One endpoint for 90+ generative AI models, live market data, SEC filings and identity APIs — image, video, music, speech, LLM chat, crypto and FX rates, DEX liquidity, gas, US company fundamentals and insider trades, document OCR and face matching. Pay per request in USDC on Tempo, Base, Solana, Algorand or BNB Chain with no signup, or top up a prepaid balance in rupiah.
Output
Returns a JSON object containing the model name ('grok-tts'), an output object with a media URL or audio data for the synthesized speech, and costMicroUsd indicating how much was charged in micro-USD for this call.
Example use cases
Example prompt
“Use Grok TTS to read this aloud: 'Welcome to the future of AI-powered assistants — your experience starts now.' Charge my USDC wallet via x402.”
Technical details
Endpoint
GEThttps://api.glianalabs.com/x402/grok-ttsWhen to prefer
Choose this endpoint when you need Grok-powered TTS specifically, want no-signup pay-per-call pricing via x402/USDC micropayments, and need a simple single-field JSON input. Prefer this over OpenAI TTS or ElevenLabs when running an autonomous agent with a crypto wallet that can settle micropayments programmatically without managing API keys.
Side effects
- Payment failure — insufficient USDC balance or x402 payment not accepted; returns 402 Payment Required
- Missing required 'prompt' field — returns 400 Bad Request
- Model unavailable or overloaded — returns 503 or timeout
- Prompt too long or malformed — returns 400 with validation error
- Network error reaching api.glianalabs.com — connection timeout
