How this service works
14 chat models (GPT + Claude), 7 image models, and Jev structured decisions. Pay per request in USDC on Base with x402.
Output
A binary WAV audio stream in RIFF/WAVE format at 24 kHz mono, returned as audio/wav content. The audio contains the synthesized speech of the provided input text using the selected model and voice.
Example use cases
Emotive podcast intro narration
“Turn this intro script into speech using the orpheus-english model with the 'diana' voice, and include a [laughs] tag after the joke — text is: 'Welcome back, folks. Today we cover the wildest AI stories of the week [laughs]. Buckle up.'”
Arabic voice announcement generation
“Synthesize this Arabic announcement using the orpheus-arabic model with the 'noura' voice: 'مرحباً بكم في المنصة الجديدة. نأمل أن تستمتعوا بتجربتكم.'”
High-quality audiobook segment
“Convert this paragraph to high-quality speech using the tts-1-hd model with the 'fable' voice at 0.9 speed: 'The old lighthouse stood at the edge of the world, its beam cutting through the fog like a whisper of hope.'”
Technical details
Endpoint
POSThttps://base.mapleai.shop/v1/audio/speech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use TTS without a subscription, especially when you want emotive speech with emotion tags (e.g. [laughs]) via Groq Orpheus, or Arabic-language voice synthesis. Ideal for agents that generate audio on demand and pay per call in USDC on Base. Prefer over OpenAI TTS directly if you want crypto-native billing or access to Orpheus voices not available on OpenAI.
