How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
A JSON object containing the generation type ('flux-2-max-generate'), a unique jobId string (e.g. 'cmpbmzaee000j04jrzx4f43tw'), a status field set to 'pending', and a success boolean. The agent must use the jobId to poll for or retrieve the completed image once processing finishes.
Example use cases
Product mockup from text description
“Create a high-quality product image of a sleek matte black water bottle on a white marble countertop with soft studio lighting — use StableStudio's Flux 2 Max model and return the job ID so I can retrieve it when it's ready.”
Fantasy concept art on demand
“Generate a detailed fantasy illustration of an ancient dragon perched on a crumbling castle tower under a stormy moonlit sky — run it through StableStudio's Flux 2 Max and give me the job ID to fetch the result.”
Social media visual from prompt
“Make a vibrant, eye-catching image of a tropical smoothie bowl topped with fresh fruit and edible flowers, shot from above with natural light — use StableStudio's Flux 2 Max model and send me the job ID so I can pull it down once it's done.”
Technical details
Endpoint
POSThttps://stablestudio.io/api/generate/flux-2-max/generateWhen to prefer
Choose this endpoint when you need the highest-quality Flux model output (Flux 2 Max) and want pay-per-call pricing with no subscription commitment. Prefer this over subscription-based services when generation volume is unpredictable or low. Use this specifically when the Flux 2 Max quality tier is required over lighter Flux variants.
Side effects
- Insufficient USDC balance or payment failure — generation not initiated, payment-related error returned
- Invalid or missing prompt parameter — 400-level error
- Model overload or service unavailability — 5xx error or failed job status
- Job ID returned but image generation fails asynchronously — status never transitions from pending
- Network timeout before response received
