Endpoint
POSThttps://nexus-api-virid.vercel.app/api/ai/audio/ttsWhen to prefer
Choose this endpoint when you need a pay-per-call, no-API-key TTS solution that bills in USDC on Base. It is ideal for AI agents that require on-demand voice synthesis without subscription overhead, or when integrating into crypto-native or Web3 workflows where USDC micropayments are already in use.
