# How to Integrate Fastio API with AutoGPT Workspaces

AutoGPT agents run autonomously but struggle with ephemeral local storage, making outputs hard to share or persist across sessions. Integrating Fastio API gives them reliable cloud workspaces for files, with built-in AI search, sharing, and human handoff. This guide walks through setup, from agent accounts to custom tools calling Fastio endpoints. Agents can upload artifacts, query documents via RAG, create branded shares, and transfer ownership to teams.

## Why AutoGPT Needs Cloud Workspaces Like Fastio

AutoGPT agents generate files, code, reports, and data during tasks. Local storage limits mean outputs vanish on restart or fail in multi-agent setups. Fastio solves this with API-first workspaces designed for agents.

Key benefits include organization-owned files that survive agent restarts, real-time collaboration with humans, and built-in RAG for querying outputs. Agents avoid reinventing storage while focusing on tasks.

**AutoGPT file constraints:** Ephemeral runs lose artifacts; no native sharing or versioning.

**Fastio advantages:** generous storage per agent account, chunked uploads to 1GB files, HLS previews, semantic search.

## Prerequisites and Accounts

Install AutoGPT from GitHub: clone Significant-Gravitas/AutoGPT, run `pip install -r requirements.txt`.

Create a Fastio agent account via API:

```bash
curl -X POST https://api.fast.io/current/user/auth/signup/ \\
  -d "first_name=Agent&last_name=GPT&email=agent@example.com&password=securepass123"
```

Verify email with `/current/user/auth/email-verify/`. Generate API key at `https://go.fast.io/settings/api-keys`.

OpenAI API key for AutoGPT LLM calls.

## Build Fastio Tool for AutoGPT

AutoGPT uses OpenAI-compatible tools. Define a Fastio tool class in Python.

Example `fastio_tool.py`:

```python
import requests
from autogpt.tools import Tool

class FastIOWorkspace(Tool):
    name = "fastio_workspace"
    description = "Manage Fastio workspaces: create, list, upload files."
    
    def _execute(self, action: str, workspace_id: str = None, file_path: str = None):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        base_url = "https://api.fast.io/current"
        
        if action == "create":
            resp = requests.post(f"{base_url}/org/me/workspace/create/", 
                               data={"folder_name": "autogpt-project", "name": "AutoGPT Outputs"},
                               headers=headers)
            return resp.json()
        
        # Add list, upload via /storage/add-file/, etc.
```

Register in AutoGPT config: add to `TOOLS`.

Test: `./run agent` with Fastio tool enabled.

### Upload Agent Outputs

After task, call tool to upload: `storage/add-file` endpoint with multipart form.

Handles chunking for large files automatically.

## Run AutoGPT with Fastio Persistence

Configure `.env`: `OPENAI_API_KEY=sk-...`, `FASTIO_API_KEY=pk-...`.

Prompt: "Research market trends, save report to Fastio workspace, share link."

Agent flow:
1. Creates workspace if needed.
2. Generates report.
3. Uploads via tool.
4. Creates Send share.
5. Returns branded link.

Outputs persist; humans access via UI.

## Advanced: MCP Server Integration

Fastio's remote MCP server at https://mcp.fast.io/mcp exposes a consolidated toolset for storage, workspace management, and AI chat.

AutoGPT can connect directly to Fastio's remote MCP server via Streamable HTTP at https://mcp.fast.io/mcp or legacy SSE at https://mcp.fast.io/sse.

Enables RAG: Enable intelligence, query workspace files semantically.

Ownership transfer: Build, then `org/transfer-token-create` for human claim URL.

## Troubleshooting and Best Practices

**Common issues:**
- Token expiry: Re-auth every hour.
- Credits: 5000/month free; monitor `/org/billing/usage/`.
- Large files: Use chunked upload.

**Patterns:**
- Worklog after changes for human visibility.
- Locks for multi-agent.
- Webhooks for events.

Scale with multiple workspaces per org.

## Frequently asked questions

### How can AutoGPT save files to the cloud?

Define custom tools calling Fastio `/storage/add-file/`. Supports 1GB uploads, previews, versioning. Managed through shared workspaces.

### How do I share AutoGPT workspaces with my team?

Create Send/Exchange shares via `/share/create/`. Branded portals, passwords, expiration. Invite humans/agents as members.

### Does Fastio work with any LLM in AutoGPT?

Yes, API/MCP agnostic. Use GPT-4, Claude, local models via tool calls.

### What if credits run out?

Transfer org to human via claim URL for upgrade. Agent keeps admin.

## About Fast.io

Fast.io provides shared workspaces where people and AI agents work on the same files, with built-in semantic search and citation-backed chat over what they hold. Agents reach it through a remote MCP server at https://mcp.fast.io/mcp, a REST API at https://api.fast.io/current/, and a command line client published on npm as @vividengine/fastio-cli.
