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, initial status ('queued'), a result URL to fetch the upscaled image once complete, a status polling URL, an estimated completion time in seconds (etaSeconds), and a maximum polling budget in seconds. The agent must poll the statusUrl until complete, then retrieve the upscaled image from resultUrl.

Example use cases

Portrait photo face enhancement

“I have this low-res JPEG headshot I need to enlarge — can you upscale it by 4x using face mode to make it look sharp and professional?”

Thumbnail to print-ready image

“This product thumbnail PNG is way too small for the banner I need to print — please upscale it 4x in auto mode so it's usable at large size.”

Old photo restoration enlargement

“I've got a small scanned old family photo as a JPEG — can you upscale it 2x with face enhancement so the faces look cleaner and it's bigger overall?”

When to prefer

Choose this endpoint when you need AI-powered image upscaling with either general (auto) or face-optimized enhancement, supporting 2x or 4x enlargement of PNG or JPEG images, and can tolerate async processing (up to ~5 minutes). Prefer face mode for portrait or headshot images. Best suited for agents that can handle polling workflows and x402 USDC micropayments.

Side effects

Invalid or corrupt base64 image data — returns error on submission
Unsupported media type (not image/png or image/jpeg) — rejected at input validation
Upscale factor not 2 or 4 — enum validation failure
Job timeout if processing exceeds pollBudgetSeconds (1200s) — result may not be available
Payment failure via x402 protocol — request blocked without $0.06 USDC
Image too large or too small for upscaling — possible server-side rejection
Network timeout while polling statusUrl
