It accepts a text prompt and optional parameters for aspect ratio (10 options from 1:1 to 21:9) and resolution (1K, 2K, or 4K). Pricing is dynamic, ranging from $0.13 to $0.24 per generation depending on resolution, with typical generation time around 10 seconds. Payment is settled in USDC on Base (EIP-155:8453) using the x402/MPP protocol — no API keys or subscriptions required.\n\nThe workflow is asynchronous: POST the generation request with a signed USDC payment header, receive a jobId with status \"pending\", then poll the job status endpoint (GET /api/jobs/{jobId}) using a SIGN-IN-WITH-X wallet signature until the job completes and returns an imageUrl. StableStudio also offers a companion edit endpoint at /api/generate/nano-banana-pro/edit that accepts 1–14 reference images for guided editing.\n\nStableStudio is part of a broader platform offering multiple image models (GPT Image 1.5, Flux 2 Pro, Grok) and video models (Sora 2, Veo 3.1, Seedance, Wan 2.6, Grok Video). The Nano Banana Pro generate endpoint is the recommended default for image tasks due to its quality-to-cost ratio. An MCP server is available via `npx -y agentcash@latest` for agent integration.","tags":["image","video","generation","nano-banana","gpt-image","grok","flux","sora","veo","seedance","wan"],"capabilities":["text-to-image","up-to-4k-resolution","multiple-aspect-ratios","dynamic-pricing","usdc-on-base-payment","async-job-polling","wallet-auth","no-api-key","mpp-protocol","x402-protocol"],"categories":["vision","image-generation"],"synonyms":["nano banana pro","text to image","AI image generation","image generator API","USDC image generation","StableStudio","pay per image","micropayment image","4K image generation","crypto image API"],"warnings":["Probe used HEAD/GET which returned 405; the endpoint is POST-only and is expected to be live (confirmed by OpenAPI spec and payment protocol details)","No standalone documentation pages found (/docs, /pricing, /api all return 404); all docs are embedded in the OpenAPI x-guidance field","Dynamic pricing means the actual charge varies by resolution/aspect ratio; the 402 challenge at call time determines the exact amount"],"endpointUrl":"https://stablestudio.dev/api/generate/nano-banana-pro/generate","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stablestudio.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.880","qualityRationale":"Full OpenAPI 3.1 schema with detailed input/output definitions, clear pricing in the guidance docs, and a live 402 MPP challenge confirmed (the endpoint is POST-only, so HEAD/GET returning 405 is expected).
