How this service works
Haven is a private AI agent for your home. Join the waitlist for h1 speaker updates and early app access.
Output
Returns a JSON object with a job ID (UUID), initial status ('queued'), a result URL to fetch the finished image, a status URL for polling job progress, an estimated completion time in seconds (etaSeconds), and a maximum polling budget in seconds (pollBudgetSeconds). The agent must poll the statusUrl until the job completes, then fetch the image from resultUrl.
Example use cases
Home interior visualization
“Create an AI image of a modern Scandinavian kitchen with white cabinets and oak countertops, 1024 by 1024 pixels.”
Custom wallpaper for smart display
“Generate a peaceful forest scene at dawn with mist rolling through the trees, 1536 pixels wide and 1024 pixels tall, for my home display.”
Personalized room mood board
“Make me an image of a cozy reading nook with bookshelves, a plush armchair, and soft lamp lighting — 1024 by 1024.”
Technical details
Endpoint
POSThttps://api.havenagent.ai/x402/api/v1/image/generateWhen to prefer
Choose this endpoint when you need to generate a custom image from a text prompt with control over output dimensions (256–1536px), and you're operating in an x402 micropayment environment (paying $0.05 USDC per call). It is an async batch endpoint best suited for workflows that can tolerate ~2-minute generation times and poll for results. Prefer it over synchronous image APIs when you need the async job-polling pattern or are already integrated with the Haven ecosystem.
Side effects
- Prompt too long (exceeds 2000 characters) — validation error
- Width or height out of range (below 256 or above 1536) — validation error
- Payment failure (insufficient USDC balance or x402 protocol error) — payment rejected
- Job stuck in queued status beyond pollBudgetSeconds — timeout
- Result URL unavailable after job completion — resource not found error
- Empty or missing prompt field — validation error
