MiniMax Speech HD for Agents
Generate high-fidelity expressive speech for $0.08 USDC. Call when you need English, Portuguese, or Spanish voiceover with emotion, speed, and pitch for up to 500 UTF-8 bytes—not a phone carrier or realtime session. Returns a validated 32 kHz mono WAV URL and SHA-256 receipt. No API key, no subscription.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
