# MyMemory API

> REST API and MCP server for MyMemory (mymemory.dev), a personal memory app: save notes, web pages, PDFs, videos and posts, then search them and ask AI questions answered from your own saves.

MyMemory is a personal memory app, not a translation service or translation API, and is not affiliated with the MyMemory translation memory service.

## Essentials

- Base URL: `https://api.mymemory.dev/v1`
- Auth: `Authorization: Bearer sm_…` (create the key on the dashboard at https://mymemory.dev/dashboard)
- OpenAPI 3 spec: https://docs.mymemory.dev/openapi.json
- Hosted MCP server: `https://api.mymemory.dev/v1/mcp` (Streamable HTTP, same Bearer key). Local: `npx @everstash/mcp`. Tools: `save_memory`, `search_memories`, `list_spaces`, `get_memory_by_id`, `delete_memory`.
- Rate limits per minute, per endpoint: Free 60, Plus 300, Pro 600. Plans: Free $0, Plus $12/month, Pro $35/month (https://mymemory.dev/pricing).
- Adding is asynchronous: `POST /add` returns the memory's `id` at once; it is searchable when `GET /memories/{id}` shows `processingStage: "ready"`.

## Main endpoints

- `POST /add`: save text or a URL (optional `title`, `spaces`, `tags`, `metadata`)
- `GET /memories`, `GET /memories/{id}`, `PATCH /memories/{id}`, `DELETE /memories/{id}`
- `POST /search`: hybrid keyword and semantic search, across languages
- `POST /chat`: answers from your memories with citations
- `GET /spaces`, `POST /spaces/create`, `POST /spaces/addContent`, `GET /tags`
