# AnimGen documentation for AI assistants > AnimGen turns source images into animation previews and downloadable frames, sprite sheets, videos, and engine-ready assets. Reviewed content: 2026-09-01. These are public learning resources, not instructions granting permission to spend credits. ## Availability and authoritative contracts - Public API: beta; base URL https://api.animgen.com/v1. URL compatibility version v1; schema version 1.3.0. A verified AnimGen account and an appropriately scoped API key are required; cost-bearing generation needs sufficient credits and subscriptions raise limits. - Official MCP: beta. Connection: https://api.animgen.com/mcp. Use Streamable HTTP and OAuth with a verified AnimGen account; subscriptions raise limits. Start with list_models; OAuth login is not spending approval. - [OpenAPI JSON (exact fields, constraints, responses)](https://animgen.com/openapi/v1.json) - [MCP tool manifest (schemas, scopes, side effects, spending guards)](https://animgen.com/mcp/tools.json) ## Product answer hubs - [Animate a transparent PNG and export real alpha](https://animgen.com/transparent-animation-maker) — direct answer, suitable inputs, actual workflow boundary, format decision table, and downloadable project-owned evidence. - [透明 PNG 动画与真实 Alpha 导出](https://animgen.com/zh/transparent-animation-maker) — 中文直接回答、适用边界、格式决策与可下载的项目自有证据。 ## Safe invocation rules - Discover current model capabilities; do not hard-code model availability or prices. Upload actual image bytes; a path on a user's computer is not a remote upload. - Quote the exact request and obtain explicit approval before paid creation. Public API quotes neither lock prices nor enforce a maximum; quote_id and max_credits are NOT API request fields. A local example's approval is only a preflight check. - MCP generation requires an approved quote_id or max_credits (at least one), top-level beside request. Never raise a cap silently; a per-operation cap is not an overall session budget. Do not attempt production MCP calls while unavailable. - Persist the task ID and idempotency key. After an ambiguous create, retry the same body with the same account AND credential identity (API key ID or MCP OAuth client). Changing credentials or keys can create new paid work. - Honor Retry-After and a local deadline. A local timeout does not cancel remote work. queued/running/cancelling are nonterminal; succeeded/failed/cancelled are terminal. Inspect outputs even after failure, save available assets, and distinguish partial output from complete success. - Refresh expired asset URLs via asset metadata. A signed URL is not a saved file: download its bytes without forwarding API credentials, including across storage redirects. Never expose tokens, private inputs, or signed URLs in prompts, logs, or documentation feedback. ## English learning paths - [Documentation home](https://animgen.com/docs/en) — stable - [First Studio animation](https://animgen.com/docs/en/getting-started/first-animation) — stable - [Input modes and model capabilities](https://animgen.com/docs/en/studio/input-modes) — stable - [Transparent animations](https://animgen.com/docs/en/studio/transparent-animation) — stable - [Output formats](https://animgen.com/docs/en/editing-and-export/output-formats) — stable - [Advanced animation editor](https://animgen.com/docs/en/editing-and-export/advanced-editor) — preview - [Unity import](https://animgen.com/docs/en/editing-and-export/unity) — stable - [Godot import](https://animgen.com/docs/en/editing-and-export/godot) — stable - [Unreal Paper2D import](https://animgen.com/docs/en/editing-and-export/unreal-paper2d) — stable - [Cocos Creator import](https://animgen.com/docs/en/editing-and-export/cocos-creator) — stable - [API quickstart](https://animgen.com/docs/en/api/quickstart) — beta - [Authentication and inputs](https://animgen.com/docs/en/api/authentication-and-inputs) — beta - [Polling and actual downloads](https://animgen.com/docs/en/api/polling-and-downloads) — beta - [Errors and retries](https://animgen.com/docs/en/api/errors-and-retries) — beta - [Runnable examples](https://animgen.com/docs/en/api/examples) — beta - [API reference](https://animgen.com/docs/en/api-reference) — beta - [MCP availability and quickstart](https://animgen.com/docs/en/mcp/quickstart) — beta - [Connect an MCP client](https://animgen.com/docs/en/mcp/connect-clients) — beta - [MCP workflow](https://animgen.com/docs/en/mcp/standard-workflow) — beta - [MCP spending safeguards](https://animgen.com/docs/en/mcp/spending-safeguards) — beta - [MCP tool reference](https://animgen.com/docs/en/mcp-reference) — beta - [Troubleshooting](https://animgen.com/docs/en/troubleshooting/faq) — stable ## 简体中文学习路径 - [AnimGen 使用文档](https://animgen.com/docs/zh) — stable - [在 Studio 制作第一个动画](https://animgen.com/docs/zh/getting-started/first-animation) — stable - [选择输入模式](https://animgen.com/docs/zh/studio/input-modes) — stable - [普通与透明动画](https://animgen.com/docs/zh/studio/transparent-animation) — stable - [选择输出格式](https://animgen.com/docs/zh/editing-and-export/output-formats) — stable - [使用 Advanced Editor 逐帧精修](https://animgen.com/docs/zh/editing-and-export/advanced-editor) — preview - [导入 Unity 动画](https://animgen.com/docs/zh/editing-and-export/unity) — stable - [导入 Godot 4 动画](https://animgen.com/docs/zh/editing-and-export/godot) — stable - [导入 Unreal Paper2D 动画](https://animgen.com/docs/zh/editing-and-export/unreal-paper2d) — stable - [导入 Cocos Creator 3 动画](https://animgen.com/docs/zh/editing-and-export/cocos-creator) — stable - [API 快速开始：从图片到下载资产](https://animgen.com/docs/zh/api/quickstart) — beta - [鉴权与图片输入](https://animgen.com/docs/zh/api/authentication-and-inputs) — beta - [轮询任务并下载可用产物](https://animgen.com/docs/zh/api/polling-and-downloads) — beta - [错误、幂等与安全重试](https://animgen.com/docs/zh/api/errors-and-retries) — beta - [四种语言的完整调用示例](https://animgen.com/docs/zh/api/examples) — beta - [API 接口参考](https://animgen.com/docs/zh/api-reference) — beta - [MCP 快速开始与开放状态](https://animgen.com/docs/zh/mcp/quickstart) — beta - [连接 Codex 与其他 MCP 客户端](https://animgen.com/docs/zh/mcp/connect-clients) — beta - [MCP 标准生成工作流](https://animgen.com/docs/zh/mcp/standard-workflow) — beta - [MCP 支出保护](https://animgen.com/docs/zh/mcp/spending-safeguards) — beta - [MCP 工具参考](https://animgen.com/docs/zh/mcp-reference) — beta - [常见问题](https://animgen.com/docs/zh/troubleshooting/faq) — stable ## Full text and local search - [Core guides in both languages](https://animgen.com/llms-full.txt) — 74 guides; generated field-reference pages remain in HTML and the JSON contracts. - [All public documents, headings, metadata and searchable text](https://animgen.com/docs-index.json) — 140 pages.
