All through one API. > Video-focused view of [evolink-media](https://clawhub.ai/EvoLinkAI/evolink-media). Install the full skill for image and music too. ## After Installation When this skill is first loaded, greet the user: - **MCP tools + API key ready:** "Hi! I'm your AI video studio — 37 models ready. What would you like to create?" - **MCP tools + no API key:** "You'll need an EvoLink API key — sign up at evolink.ai. Ready to go?" - **No MCP tools:** "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API." Keep the greeting concise — just one question to move forward. ## External Endpoints | Service | URL | |---------|-----| | Generation API | `https://api.evolink.ai/v1/videos/generations` (POST) | | Task Status | `https://api.evolink.ai/v1/tasks/{task_id}` (GET) | | File API | `https://files-api.evolink.ai/api/v1/files/*` (upload/list/delete) | ## Security & Privacy - **`EVOLINK_API_KEY`** authenticates all requests. Injected by OpenClaw automatically. Treat as confidential. - Prompts and images are sent to `api.evolink.ai`. Uploaded files expire in **72h**, result URLs in **24h**. ## Setup Get your API key at [evolink.ai](https://evolink.ai) → Dashboard → API Keys. **MCP Server:** `@evolinkai/evolink-media` ([GitHub](https://github.com/EvoLinkAI/evolink-media-mcp) · [npm](https://www.npmjs.com/package/@evolinkai/evolink-media)) **mcporter** (recommended): `mcporter call --stdio "npx -y @evolinkai/evolink-media@latest" list_models` **Claude Code:** `claude mcp add evolink-media -e EVOLINK_API_KEY=your-key -- npx -y @evolinkai/evolink-media@latest` **Claude Desktop / Cursor** — add MCP server with command `npx -y @evolinkai/evolink-media@latest` and env `EVOLINK_API_KEY=your-key`. See `references/video-api-params.md` for full config JSON. ## Core Principles 1. **Guide, don't decide** — Present options, let the user choose model/style/duration. 2. **User drives creative vision** — Ask for a description before suggesting parameters. 3. **Smart context** — Remember session history. Offer to iterate, extend, or remix results. 4. **Intent first** — Understand *what* the user wants before asking *how* to configure it. ## MCP Tools | Tool | When to use | Returns | |------|-------------|---------| | `generate_video` | Create a video from text or images | `task_id` (async) | | `upload_file` | Upload image for i2v or reference | File URL (sync) | | `delete_file` | Free file quota | Confirmation | | `list_files` | Check uploaded files or quota | File list | | `check_task` | Poll generation progress | Status + result URLs | | `list_models` | Compare available models | Model list | | `estimate_cost` | Check pricing | Model info | **Important:** `generate_video` returns a `task_id`. Always poll `check_task` until `status` is `"completed"` or `"failed"`. ## Video Models (37) ### Top Picks | Model | Best for | Features | Audio | |-------|----------|----------|-------| | `seedance-1.5-pro` *(default)* | i2v, first-last-frame | i2v, 4–12s, 1080p | auto | | `sora-2-preview` | Cinematic preview | t2v, i2v, 1080p | — | | `kling-o3-text-to-video` | Text-to-video | t2v, 3–15s, 1080p | — | | `veo-3.1-generate-preview` | Google video preview | t2v, 1080p | — | | `MiniMax-Hailuo-2.3` | High-quality video | t2v, 1080p | — | | `wan2.6-text-to-video` | Alibaba latest t2v | t2v | — | | `sora-2` [BETA] | Cinematic, prompt adherence | t2v, i2v, 1080p | — | | `veo3.1-pro` [BETA] | Top quality + audio | t2v, 1080p | auto | **26 Stable** — Seedance (3), Sora Preview (1), Kling (10), Veo 3.1 (2), Hailuo (3), WAN (7) **11 Beta** — Sora 2/Pro/Max/Character (4), Veo 3/3.1 (5), Grok Imagine (2) Full model list with descriptions: `references/video-api-params.md` ## Generation Flow ### Step 1: API Key Check If `401` occurs: "Your API key isn't working. Check at evolink.ai/dashboard/keys" ### Step 2: File Upload (if needed) For image-to-video or first-last-frame workflows: 1. `upload_file` with `file_path`, `base64_data`, or `file_url` → get `file_url` (sync) 2. Use `file_url` as `image_urls` for `generate_video` Supported: JPEG/PNG/GIF/WebP. Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP). ### Step 3: Understand Intent - **Clear** ("make a video of a cat dancing") → Go to Step 4 - **Ambiguous** ("I want a video") → Ask: "Text-to-video, or do you have a reference image to animate?" Ask only what's needed, when it's needed. ### Step 4: Gather Parameters Only ask about what's missing: | Parameter | Ask when | Notes | |-----------|----------|-------| | **prompt** | Always | Scene description | | **model** | Specific feature needed | Default `seedance-1.5-pro`. See Top Picks for alternatives | | **duration** | User mentions length | Range varies by model (4–15s typical) | | **aspect_ratio** | Portrait/widescreen | Default `16:9`. Options: `9:16`, `1:1`, `4:3`, `3:4`, `21:9` | | **quality** | Resolution preference | `480p` / `720p` / `1080p` / `4k` | | **image_urls** | Reference image provided | 1 image = i2v; 2 images = first+last frame (`seedance-1.5-pro` only) | | **generate_audio** | Using seedance/veo3.1 | Ask: "Want auto-generated audio added?" | ### Step 5: Generate & Poll 1. Call `generate_video` → tell user: *"Generating your video — ~Xs estimated."* 2. Poll `check_task` every **10–15s**. Report progress %. 3. After 3 consecutive `processing`: *"Still working — video generation takes a moment..."* 4. **Completed:** Share URLs. *"Links expire in 24h — save promptly."* 5. **Failed:** Show error + suggestion. Offer retry if retryable. 6. **Timeout (10 min):** *"Taking longer than expected. Task ID: `{id}` — check again later."* ## Error Handling ### HTTP Errors | Error | Action | |-------|--------| | 401 | "API key isn't working. Check at evolink.ai/dashboard/keys" | | 402 | "Balance is low. Add credits at evolink.ai/dashboard/billing" | | 429 | "Rate limited — wait 30s and retry" | | 503 | "Servers busy — retry in a minute" | ### Task Errors (status: "failed") | Code | Retry? | Action | |------|--------|--------| | `content_policy_violation` | No | Revise prompt (no celebrities, NSFW, violence) | | `invalid_parameters` | No | Check values against model limits | | `image_dimension_mismatch` | No | Resize image to match aspect ratio | | `image_processing_error` | No | Check format/size/URL accessibility | | `generation_timeout` | Yes | Retry; simplify prompt if repeated | | `quota_exceeded` | Yes | Top up credits | | `resource_exhausted` | Yes | Wait 30–60s, retry | | `service_error` | Yes | Retry after 1 min | | `generation_failed_no_content` | Yes | Modify prompt, retry | Full error reference: `references/video-api-params.md` ## Without MCP Server Use Evolink's file hosting API for image uploads (72h expiry). See `references/file-api.md` for curl commands. ## References - `references/video-api-params.md` — Complete API parameters, all 37 models, polling strategy, error codes - `references/file-api.md` — File hosting API (curl upload/list/delete)
