Endpoint
POSThttps://blockrun.ai/v1/images/generationsWhen to prefer
Use this endpoint when you need programmatic, pay-per-call image generation via OpenAI's GPT-Image models without managing an OpenAI account directly — ideal for AI agents that need on-demand image creation with crypto micropayments (x402 protocol) and no subscription overhead.
Side effects
- Invalid or unsupported model ID returns an error
- Prompt violates content policy and is rejected
- Unsupported image size string causes validation error
- Network or gateway timeout for complex prompts
- Payment failure (insufficient balance or x402 auth issue) blocks the request
- n exceeds maximum allowed number of images per call
