x402
utility

Create one narrated still-image MP4 for $0.02 USDC: a bounded FLUX Schnell visual, Kokoro voiceover, and first-party composition in one agent-ready result. Call for a short social post, announcement, product card, or explainer—not generative motion, timeline editing, captions, music, or a full video-production suite. Returns durable MP4, image, and WAV URLs with SHA-256, actual provider source, cost, and margin receipt; no buyer API key or subscription.
