How this service works
Generate a short video clip from a text prompt at a flat price per clip: a four-second 720p clip returned inline as base64 MP4, with the duration and resolution locked so the price never moves. Use it when an agent needs motion rather than a still, and needs to know the cost before it calls.
Output
Returns a JSON object containing an array with the generated video as a base64-encoded MP4 (b64_json), its media type (video/mp4), resolution (720p), aspect ratio, and duration in seconds (~4s). Also includes the model name (google/veo-3.1-lite), total generation time in seconds, and a Unix timestamp of creation.
Example use cases
Social media reel from text idea
“Make me a vertical 9:16 video clip of a neon-lit city street at night with rain falling and people walking under umbrellas — I want to post it as a short reel.”
Product concept visualization
“Create a 16:9 video showing a sleek smartwatch rotating on a clean white background with soft studio lighting, so I can use it as a concept teaser.”
Animated scene for storytelling
“Generate a short video clip of an astronaut floating in space with Earth visible below, in widescreen 16:9 format, for a sci-fi short story I'm working on.”

Endpoint
POSThttps://agent402.tools/v1/videos/generationsWhen to prefer
Choose this endpoint when you need on-demand, pay-per-call AI video generation with no API key or account signup, using only a crypto wallet for identity and payment. It is ideal for AI agents operating autonomously in agentic finance or x402 payment flows. Prefer it over subscription-based video APIs when you need low-commitment per-call billing in USDC, or when integrating into an agent stack already using the Agent402 tool suite.
Side effects
- Prompt exceeds 2,000 character limit — request rejected
- Invalid aspect_ratio value outside '16:9' or '9:16' enum — validation error
- Insufficient USDC balance or failed x402 payment — 402 Payment Required
- Model generation timeout due to long processing times (~40s)
- Content policy violation on prompt — generation refused
