# Fetching Data from Arweave

Once you have a transaction ID (txid) or ArNS name, there are several ways to fetch the associated data from the Arweave network. This guide covers the main approaches available to developers.

# Overview

When you need to retrieve data stored on Arweave, you have multiple options depending on your use case:

• HTTP API: Direct HTTP requests to gateway endpoints
• Arweave.js: JavaScript/TypeScript SDK for programmatic access
• ARIO Wayfinder: Intelligent routing and verification protocol

# Available Methods

# HTTP API

The simplest approach using standard HTTP requests to Arweave gateways. Perfect for basic data retrieval and when you want minimal dependencies.

Best for:

• Simple data fetching
• Server-side applications
• When you want to avoid additional packages

# Arweave.js

The official JavaScript/TypeScript SDK that provides a comprehensive interface to the Arweave network.

Best for:

• JavaScript/TypeScript applications
• Complex Arweave operations
• When you need transaction metadata and data

# ARIO Wayfinder

A protocol that provides decentralized, cryptographically verified access with intelligent gateway routing.

Best for:

• Production applications requiring reliability
• When you need automatic gateway selection
• Applications requiring data verification

# Quick Comparison

# Getting Started

Choose the method that best fits your needs:

1. Start with HTTP API if you want the simplest approach
2. Use Arweave.js if you're building a JavaScript/TypeScript application
3. Consider Wayfinder if you need production-grade reliability and verification

Each method page includes installation instructions, basic usage examples, and links to more detailed documentation.
