Edit an image with a prompt instead of a mask
Image-to-image editing through one endpoint: send a source image and a prompt, get the edit back. Priced per edit in USDC, quoted before the call runs.
What it does
Send a source image (a URL or inline data, as JSON or multipart) and a prompt describing the change; the edited image comes back the same way a generated one does. The card lists only the models the editing route accepts — several image models generate but do not edit.
The OpenAI-family models also take a mask for inpainting a single region; the Google-family models edit from the prompt alone. Both accept more than one source image for a fusion edit, each up to its own limit, and a mask cannot be combined with multiple images.
The call
One endpoint, priced in dollars before it runs and settled in USDC. No API key and no account — the request pays for itself.
POST /api/v1/images/image2image
Host: blockrun.aiWhy per call
No seat, no minimum, no contract per vendor. Each request is quoted in dollars before it runs and settles on-chain, so an agent can pay for its own work without a human holding a credit card. How the payment works →

Questions
How is this different from generation?
Generation starts from a prompt alone; editing starts from an image you supply and changes it.
What does an edit cost?
The same per-image rate as generation on the model you pick, quoted before the request runs.
Do I need to supply a mask?
No. The prompt describes the change; no mask channel is required.
Which formats are accepted?
Standard web image formats, sent as a URL or inline data — the docs carry the exact request shape.
