How to Use Fast.io API for Batch File Operations
The Fast.io API batch file operations guide shows developers how to handle multiple file uploads, downloads, and management tasks at scale. Build on workspaces, shares, and chunked upload sessions to process batches efficiently in agent workflows. This tutorial covers authentication, key endpoints, error handling, and optimization tips grounded in official API docs.
### What Are Batch File Operations with the Fast.io API?
Batch file operations involve uploading, downloading, or processing multiple files programmatically via the Fast.io API. This is common in agentic workflows where AI agents need to ingest datasets, media libraries, or document collections into shared workspaces.
Fast.io workspaces provide the foundation for batch operations. Each workspace supports file organization, inline previews, semantic search, and AI chat over indexed content. Shares extend this for external collaboration.
Key API capabilities include chunked uploads for large files, file locks for concurrent access control, and activity polling to track batch progress without constant polling of individual files.
### How to Set Up Authentication and Start Batch Uploads
Start with authentication. Use API keys granted by human users or PKCE OAuth for browser-based flows. Scoped keys limit access to specific organizations, workspaces, or shares. Example: Create an upload session for each file in your batch: ``` POST https://api.fast.io/v1/workspaces/{workspaceId}/upload_session Authorization: Bearer {api_key}

### Best Practices for Large-Scale Batch Operations
Parallelize uploads across multiple API keys or connections to maximize throughput. Enable intelligence on workspaces for automatic indexing post-upload. This supports semantic search and RAG chat over your batch files. Implement retries with exponential backoff for transient errors like rate limits. Fast.io. For agent handoffs, use ownership transfer after batch population. Workspace intelligence. For optimal performance, test concurrency limits and adjust based on your observed throughput.
### Common Errors and Troubleshooting Batch Jobs
Rate limits: Space requests 1s apart. Check response headers for remaining quota. Chunk failures: Resume from last offset in upload session. Permission issues: Verify scope includes write to target workspace. Fast.io error codes. Implement structured logging to capture request IDs and correlate failures across services.
Frequently Asked Questions
How do I upload multiple files in batch using Fast.io API?
Use a loop to create upload sessions for each file and upload chunks in parallel where possible. Target a workspace endpoint for organized storage.
What are the limits for batch file operations?
Fast.io offers a free agent tier with storage and agent tooling for testing this workflow.
Can agents perform batch operations autonomously?
Yes, agent accounts have free persistent storage and API access via MCP server or direct REST calls.
How to handle concurrent batch uploads?
Use file locks and activity polling to coordinate access.
