# Media Generation with StableStudio Generate images and videos via x402 payments at `https://stablestudio.dev`. ## Setup If the agentcash MCP is not yet installed, see [rules/getting-started.md](rules/getting-started.md) for installation and wallet setup. ## Pricing All generation endpoints are **dynamically priced** async jobs. The static price advertises a range (up to $10; seedance up to $20) — the exact price depends on your options (quality, resolution, duration) and is quoted via x402 before payment, so agentcash shows the real cost per request. Verified sample quotes: gpt-image-2 $0.21 (defaults) / $0.01 (low quality, 1024x1024); flux-2-max $0.07 (defaults); seedance t2v $0.36 (4s, 480p). ## Quick Reference ### Image Models | Model | Endpoint | Cost | Time | Edit? | |-------|----------|------|------|-------| | **gpt-image-2** (default) | `gpt-image-2/generate` | $0.01-0.21 by quality/size | can take minutes | Yes | | gpt-image-1.5 | `gpt-image-1.5/generate` | dynamic | ~3s | Yes | | nano-banana-pro | `nano-banana-pro/generate` | dynamic | ~10s | Yes | | nano-banana | `nano-banana/generate` | dynamic | ~5s | Yes | | grok | `grok/generate` | dynamic | ~3s | Yes | | flux-2-pro | `flux-2-pro/generate` | dynamic | ~5s | Yes | | flux-2-max | `flux-2-max/generate` | ~$0.07 at defaults | — | Yes | All endpoints are prefixed with `https://stablestudio.dev/api/generate/`. Edit endpoints use `/edit` instead of `/generate`. ### Video Models | Model | Endpoint | Cost | Time | |-------|----------|------|------| | **veo-3.1** (default) | `veo-3.1/generate` | dynamic | 1-2min | | veo-3.1-fast | `veo-3.1-fast/generate` | dynamic | ~30s | | grok-video | `grok-video/generate` | dynamic | ~17s | | seedance (Seedance 2 Pro) | `seedance/t2v` or `seedance/i2v` | dynamic, up to $20 ($0.36 for 4s/480p) | ~1min | | seedance-fast (Seedance 2 Fast) | `seedance-fast/t2v` or `seedance-fast/i2v` | dynamic, up to $20 | ~40s | | wan-2.6 | `wan-2.6/t2v` or `wan-2.6/i2v` | dynamic | 2-5min | | sora-2 | `sora-2/generate` | dynamic | 1-3min | | sora-2-pro | `sora-2-pro/generate` | dynamic | 2-5min | ### SVG Vectorization | Model | Endpoint | Cost | |-------|----------|------| | arrow-1.1 | `arrow-1.1/vectorize` | dynamic | | arrow-1.1-max | `arrow-1.1-max/vectorize` | dynamic | ## Image Generation **Default: gpt-image-2.** This is the best default image model. Note: it can take minutes — poll the jobId and do **not** resubmit pending jobs. Use it unless the user specifically requests a different model or has a strong reason (e.g., speed, budget, or ultra-wide aspect ratios from grok). ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/gpt-image-2/generate", method="POST", body={ "prompt": "a cat wearing a space helmet, photorealistic", "quality": "high", "size": "1536x1024" } ) ``` **gpt-image-2 options:** - `quality`: "low", "medium", "high" (affects cost: ~$0.01 low to ~$0.21 high) - `size`: "1024x1024", "1536x1024", "1024x1536", "auto" - `background`: "opaque", "auto". `output_format`: "png", "jpeg", "webp" ### Other Image Models **gpt-image-1.5** -- Fastest GPT image model. Same schema as gpt-image-2; its `background` additionally supports "transparent": ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/gpt-image-1.5/generate", method="POST", body={ "prompt": "a watercolor painting of a mountain lake", "quality": "high", "size": "1536x1024" } ) ``` Options: `quality`: "low"/"medium"/"high". `size`: "1024x1024", "1536x1024", "1024x1536", "auto". **nano-banana-pro** -- High quality, supports up to 4K: ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/nano-banana-pro/generate", method="POST", body={ "prompt": "a cat wearing a space helmet, photorealistic", "aspectRatio": "16:9", "imageSize": "2K" } ) ``` Options: `aspectRatio`: "1:1", "2:3", "3:2", "3:4", "4:3", "4:5", "5:4", "9:16", "16:9", "21:9". `imageSize`: "1K", "2K", "4K". **nano-banana** -- Budget option. Adds extreme aspect ratios ("1:4", "4:1", "1:8", "8:1") on top of nano-banana-pro's, `imageSize` adds "512", and supports `thinkingLevel`: "minimal" (fastest) or "high" (best quality). **grok** -- Fast, wide aspect ratio support. Note: uses `aspect_ratio` (underscore): ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/grok/generate", method="POST", body={ "prompt": "neon cyberpunk cityscape at night", "aspect_ratio": "16:9" } ) ``` Options: `aspect_ratio`: "1:1", "16:9", "9:16", "4:3", "3:4", "3:2", "2:3", "2:1", "1:2", "19.5:9", "9:19.5", "20:9", "9:20". **flux-2-pro** -- High quality with resolution control: ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/flux-2-pro/generate", method="POST", body={ "prompt": "editorial photo of a vintage car in golden hour light", "aspect_ratio": "3:2", "resolution": "2 MP" } ) ``` Options: `aspect_ratio`: "1:1", "16:9", "9:16", "3:2", "2:3", "4:5", "5:4", "4:3", "3:4". `resolution`: "0.5 MP", "1 MP", "2 MP". **flux-2-max** -- Same schema as flux-2-pro, higher quality tier; `resolution` additionally supports "4 MP". ## SVG Vectorization Convert any public image URL to SVG with **arrow-1.1** (or **arrow-1.1-max** for higher quality): ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/arrow-1.1/vectorize", method="POST", body={ "image": "https://example.com/logo.png" } ) ``` Optional: `target_size` (square resize target in pixels, 128-4096, default 1024), `auto_crop` (crop to dominant subject, default false). Poll the returned jobId for the SVG result. ## Video Generation **Recommended: veo-3.1** (best quality) ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/veo-3.1/generate", method="POST", body={ "prompt": "a timelapse of clouds moving over mountains", "durationSeconds": "6", "aspectRatio": "16:9" } ) ``` **veo-3.1 options:** - `durationSeconds`: "4", "6", "8" - `aspectRatio`: "16:9", "9:16" - `resolution`: "720p", "1080p" - `negativePrompt`: things to avoid veo-3.1 also supports image inputs via `imageMode` ("none", "first-frame", "reference", "interpolation"): **frame interpolation** between `image` and `lastFrame` blob URLs, or up to 3 `referenceImages` for style guidance. **veo-3.1-fast** -- Same schema as veo-3.1, cheaper, ~30s instead of 1-2min. ### Other Video Models **seedance** (Seedance 2 Pro) -- High quality, up to 15s. Use `seedance/t2v` (text-to-video) or `seedance/i2v` (image-to-video): ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/seedance/t2v", method="POST", body={ "prompt": "a bird taking flight from a branch in slow motion", "duration": "8", "aspectRatio": "16:9", "outputResolution": "1080p" } ) ``` Required: `prompt`, `duration`, `aspectRatio`, `outputResolution`. Options: `duration`: "4"-"15". `aspectRatio` (camelCase): "1:1", "3:4", "4:3", "16:9", "9:16", "21:9". `outputResolution`: "480p", "720p", "1080p". Optional `upscaleResolution`: "4k". For i2v, add `"image": "https://blob-url..."`. Unknown fields are rejected. **seedance-fast** (Seedance 2 Fast) -- Same schema, cheaper and faster; `outputResolution` maxes out at "720p". **grok-video** -- Cheapest short video option: ```mcp agentcash.fetch( url="https://stablestudio.dev/api/generate/grok-video/generate", method="POST", body={ "prompt": "a candle flame flickering", "duration": "6", "resolution": "720p", "aspect_ratio": "16:9" } ) ``` Options: `duration`: "3", "6", "9", "12", "15". `resolution`: "480p", "720p". `aspect_ratio`: "1:1", "16:9", "9:16", "4:3", "3:4", "3:2", "2:3". Optional `image` URL for image-to-video. **wan-2.6** -- Budget, supports t2v and i2v. `duration`: "5", "10", "15". t2v uses `size` ("1280*720", "720*1280", "1920*1080", "1080*1920"); i2v uses `resolution` ("720p", "1080p") and `image`. **sora-2** -- `seconds`: "4", "8", "12". `size`: "1280x720", "720x1280". Optional `input_reference` image URL for image-to-video. **sora-2-pro** -- Premium. Same `seconds` as sora-2 ("4", "8", "12"); `size` adds "1792x1024", "1024x1792". ## Job Polling
