The All-In-One API

Firekeeper

The future of Web3 development is here. The thirdweb API is a revolutionary unified interface that brings together every tool you need to build next-generation blockchain applications. From AI-powered smart contract interactions to seamless user authentication across 13+ providers, this isn't just an API—it's your gateway to building the decentralized applications of tomorrow.

Imagine building Web3 applications with the simplicity of Web2. The thirdweb API makes this reality by providing a single, elegant interface to all the blockchain functionality you need. No more juggling multiple services, complex integrations, or fragmented workflows. Everything you need is unified, optimized, and ready to power your next breakthrough application.

Gone are the days of implementing dozens of authentication patterns. The thirdweb API revolutionizes user onboarding with a universal two-step authentication system that works with every modern authentication method:

• One Initiation Endpoint (/v1/auth/initiate) for ALL methods
• One Completion Endpoint (/v1/auth/complete) for ALL methods
• 13+ OAuth Providers: Google, Apple, Discord, GitHub, X, Coinbase, Farcaster, and more
• Modern Methods: SMS, Email, Passkeys, SIWE (Sign-In with Ethereum)
• Custom Solutions: JWT tokens and custom authentication endpoints

// Initialize ANY authentication method
POST /v1/auth/initiate
{
  "method": "email" | "sms" | "oauth" | "passkey" | "siwe",
  // method-specific parameters
}
 
// Complete ANY authentication
POST /v1/auth/complete
{
  "method": "email",
  // completion data
}
// Result: User wallet + JWT token ready to use

No more complexity. No more confusion. Just authentication that works.

The thirdweb API isn't just about authentication—it's a comprehensive platform with 25 powerful endpoints organized into intuitive categories:

Universal authentication flow supporting every modern method

Complete user identity and profile management

Full wallet functionality: balances, transactions, tokens, NFTs, signing, and asset transfers

Deploy, read, write, and manage smart contracts with ease

Advanced transaction management and monitoring

Revolutionary payment infrastructure with token swapping

Token discovery, search, and ownership tracking

Industry-first natural language blockchain interactions

The world's first natural language blockchain interface:

POST /ai/chat
{
  "messages": [{"role": "user", "content": "Send 0.01 ETH to vitalik.eth"}],
  "context": {"from": "0x1234...", "chain_ids": [1]}
}
// AI understands, prepares transaction, handles everything

• Deploy smart contracts through conversation
• Execute complex DeFi strategies with plain English
• Automated transaction preparation and optimization
• Context-aware blockchain operations

Build payment flows that just work:

• Token Swapping: Optimal routes across DEXes automatically
• Product Payments: Create payment links with hosted checkout
• Universal Assets: ETH, ERC-20, NFTs, all handled seamlessly

• Batch Operations: Read/write multiple contracts in one call
• Auto-deployment: Deploy contracts with bytecode + ABI
• Real-time Data: Live transaction and event monitoring
• Metadata Integration: Rich contract information automatically

• Multi-chain Balances: Query assets across all networks
• Universal Transactions: Consistent interface for any blockchain
• Chain-agnostic Development: Write once, deploy everywhere

The thirdweb API empowers you to build applications that were impossible before:

• Seamless in-game asset trading

1. Authentication Flow: Complete rewrite required
2. User Management: /v1/wallets/user/* → /v1/accounts/*
3. Endpoint Naming: Several endpoints renamed for clarity
4. Response Structures: Some response formats standardized

Despite breaking changes, migration provides:

• 50% fewer authentication endpoints to integrate
• Unified error handling across all endpoints
• Future-proof architecture for new features
• Enhanced security with modern auth patterns
