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 containing a job ID (UUID), initial status ('queued'), a resultUrl to fetch the finished edited image, a statusUrl for polling job progress, estimated completion time in seconds (etaSeconds, typically up to 300s), and a pollBudgetSeconds indicating the maximum polling window (1200s). The agent must poll the statusUrl until the job completes, then fetch the image from resultUrl.
Example use cases
Home interior style swap
“I have a photo of my living room — can you edit it so the walls are painted a deep navy blue and the furniture looks modern Scandinavian? Output it as a PNG. Here's the base64 image.”
Product photo background removal
“Take this product photo in JPEG and edit out the messy warehouse background, replacing it with a clean white studio backdrop. Here's the base64 of the image.”
Portrait touch-up with negative prompt
“Edit this portrait so the lighting looks golden hour and warm, but make sure there's no blurriness or noise — use the negative prompt 'blurry, grainy, low quality'. Output as PNG. Here's the base64 image.”
Technical details
Endpoint
POSThttps://api.havenagent.ai/x402/api/v1/image/editWhen to prefer
Choose this endpoint when you need to modify an existing image using a natural language prompt rather than generating one from scratch. It is well-suited for tasks like style transfer, background replacement, inpainting, or content modification on a provided image. Prefer this over text-to-image generation endpoints when the user has a source image they want altered. It uses the x402 payment protocol (0.1 USDC per call), so it is appropriate in agent contexts where micropayments are supported.
Side effects
- Invalid or malformed base64 image data causing a 400 error
- Unsupported media type (anything other than image/png or image/jpeg)
- Prompt exceeding 2000 characters causing validation failure
- Payment failure via x402 protocol resulting in 402 response
- Job timeout if result is not ready within pollBudgetSeconds (1200s)
- Server-side generation failure leading to an error status on the job
