Endpoint
POSThttps://x402.forgemesh.io/ttsWhen to prefer
Prefer this endpoint when you need pay-per-call TTS with no API key or subscription setup, especially for voice agents, IVR systems, or low-volume audio content generation where per-call micropayment (x402/USDC) is acceptable. Choose the premium tier at voice.forgemesh.io if you need more than the basic voice set or multilingual support (20 voices, 31 languages).
Side effects
- Text exceeds 2000 character limit — request rejected
- Invalid or unsupported voice ID specified — falls back to default or errors
- x402 payment not provided or insufficient USDC — 402 Payment Required response
- Neural engine unavailable — 5xx service error
- Empty text field — returns error or silence
