HappyHorse CLI & API ([happyhorse.com/cli](https://happyhorse.com/cli)) is a developer-focused integration suite for the HappyHorse AI video generation engine (featuring HappyHorse 1.0 & 1.1). Designed for AI coding agents, automation pipelines, and software engineers, it allows teams to execute text-to-video, image-to-video, and reference-guided video rendering directly from the terminal or embed generative video capabilities into AI agent workflows (such as Claude Code, OpenCode, or custom CLI assistants).

Generating AI video typically requires interacting with manual web dashboards or complex multi-step creative interfaces. The HappyHorse CLI streamlines video production by packaging HappyHorse’s joint audio-video generation pipeline into scriptable terminal commands and API calls, enabling developers to automate content pipelines, programmatically animate product shots, and equip AI agents with direct video synthesis capabilities.

Key Capabilities and Developer Workflows

• Agent-Ready Command Interface: Provides modular CLI commands designed to be registered directly with coding assistants and agent runtimes. Agents can trigger video generation tasks autonomously as part of wider research, social media scheduling, or marketing automation loops.

• Scriptable Multi-Modal Generation: Developers can pass detailed camera trajectories, lighting parameters, and aspect ratios via terminal flags or JSON payloads, enabling precise programmatic control over cinematic motion.

• Automated E-Commerce & Asset Pipelines: Allows developers to build automated backend jobs that convert flat product catalog photos or dynamic database entries into engaging, animated marketing reels without manual rendering.

• Zero-Pipeline Audio Integration: Because the underlying model handles synchronized environmental audio and phoneme-level lip-syncing natively, CLI renders output ready-to-use MP4 files without requiring separate audio synthesis or dubbing tools.
