Image Generation APIs for AI Agents
Access Sora 2, Veo 3.1, GPT Image, Flux 2 Pro, Grok, and more through a single API. No subscriptions — pay only for what you generate.

How It Works
Send a POST request with your prompt and parameters to any supported model endpoint. The API returns your generated image or video, and you pay only for that single generation.
Authentication uses x402 micropayments through AgentCash. There are no API keys to manage, no subscription tiers to navigate, and no monthly minimums. Each generation costs between $0 and $10 depending on the model and output complexity.
Supported Models for Image Generation
GPT Image 1 and 1.5 support both generation from text prompts and editing of existing images. Flux 2 Pro offers high-fidelity image generation and editing. Grok Image provides generation and editing endpoints.
Nano Banana and Nano Banana Pro are available for both generation and editing workflows. Each model has distinct strengths in style, resolution, and prompt adherence, so you can route requests to whichever model fits your use case.
Supported Models for Video Generation
Sora 2 and Sora 2 Pro generate video from text prompts. Veo 3.1 is available in standard and fast variants for different latency and quality tradeoffs.
Wan 2.6 and Seedance (including Seedance Fast) support both text-to-video and image-to-video workflows, letting you animate still images or generate video from scratch.
Grok Video rounds out the video model roster with its own text-to-video generation endpoint.
Job Management
Long-running generations are tracked as jobs. Use the GET /api/jobs endpoint to list all your jobs, check individual job status by ID, or soft-delete failed jobs to keep your workspace clean.
Upload endpoints let you send source images for image-to-video or editing workflows. You receive a client token for direct upload, then confirm with the final blob URL.
Use cases
Automated product image creation
Generate product mockups and lifestyle imagery programmatically by sending text descriptions to GPT Image or Flux 2 Pro endpoints, then downloading results for your e-commerce catalog.
AI agent visual content pipeline
Let your AI agent generate illustrations, diagrams, or social media graphics on demand by calling image generation endpoints as part of an automated content workflow.
Video ad generation from text briefs
Pass creative briefs as text prompts to Sora 2 or Veo 3.1 to produce short video clips for advertising, then review results via the job status endpoint.
Image-to-video animation
Upload a still image and use Wan 2.6 or Seedance i2v endpoints to animate it into a short video, useful for bringing product photos or artwork to life.
Batch image editing
Send existing images to GPT Image or Grok edit endpoints for programmatic modifications like background removal, style transfer, or object insertion at scale.
Multi-model comparison testing
Route the same prompt to multiple model endpoints in parallel to compare output quality, style, and generation time, then select the best model for production use.

Frequently asked questions
What authentication method does this API use?
Requests are authenticated via x402 micropayments and the MPP protocol through AgentCash. No API key signup is needed — you pay per generation directly from your AgentCash wallet.
How much does each generation cost?
Pricing ranges from $0 to $10 per generation depending on the model and output parameters. Simple image generations tend to cost less, while high-resolution video generations from premium models like Sora 2 Pro cost more. The upload endpoint costs $0.01.
Which image models are available?
GPT Image 1, GPT Image 1.5, Flux 2 Pro, Grok Image, Nano Banana, and Nano Banana Pro. Most support both generation from text and editing of existing images.
Which video models are available?
Sora 2, Sora 2 Pro, Veo 3.1, Veo 3.1 Fast, Wan 2.6, Seedance, Seedance Fast, and Grok Video. Wan 2.6 and Seedance variants support both text-to-video and image-to-video.
How do I track long-running video generations?
Each generation creates a job. Poll GET /api/jobs/{jobId} to check status. You can list all jobs with GET /api/jobs and clean up failed ones with DELETE /api/jobs/{jobId}.
Do I need a subscription?
No. Every generation is pay-per-use with no subscription, no monthly commitment, and no minimum spend. You only pay when you make a request.
