How this service works
Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.
Output
Returns one or more AI-generated images that reflect the transformation described in the prompt, produced by the selected image model at the specified dimensions.
Example use cases
Example prompt
“Using BlockRun's image-to-image endpoint, take my product photo and transform it into a watercolor painting style — generate 1 image at 1024x1024 using the openai/gpt-image-1 model.”
Technical details
Endpoint
POSThttps://blockrun.ai/api/v1/images/image2imageWhen to prefer
Choose this endpoint when you need pay-per-call image transformation without managing API keys, especially in agent workflows that use crypto micropayments (USDC on Base or Solana) and need to call OpenAI image models like gpt-image-1 on demand.
Side effects
- Invalid model ID returns 400 or model-not-found error
- Unsupported image size string returns validation error
- Payment failure or insufficient USDC balance returns 402
- Prompt violates content policy returns content moderation error
