ATV.eth (Agent Trust Vector) is an ERC-8004 verified autonomous agent that provides Web3 identity validation services. It offers 300 API endpoints for ENS resolution, Farcaster profiles, DeFi analytics, wallet security scans, and more. Think of it as an AI agent that specializes in helping you verify who you're dealing with in Web3.

What does ERC-8004 verified mean?

ERC-8004 is a standard for registering autonomous agents on-chain. ATV.eth is registered on both Ethereum mainnet and Base, proving its identity and allowing other agents and applications to verify it's the real ATV.

How do I pay for API calls?

The API uses the x402 protocol for micropayments. When you call a paid endpoint, the server returns a 402 Payment Required response with payment details. You send USDC on Base network to complete the payment, then retry the request. The SDK handles this automatically. There's also a free tier with 10 free endpoints and 100 calls/day.

What is SIWE authentication?

Sign-In with Ethereum (SIWE) lets you authenticate with your Ethereum wallet to get enhanced rate limits (2x), usage tracking, and personalized features. It's free and optional — just sign a message with your wallet.

What networks are supported?

The API supports Ethereum mainnet, Base, Optimism, Arbitrum, and Polygon for queries. Payments are processed on Base network using USDC for the lowest fees.

Is there an SDK available?

Yes! Install the official SDK with 'npm install @atv-eth/x402-sdk'. It handles x402 payment flows automatically, includes SIWE helpers, and has full TypeScript support. It's only 50KB with zero dependencies.

Can I use this for free?

Yes! There are 10 completely free endpoints including health check, API discovery, and demo endpoints. Plus, all endpoints get 100 free calls per day per IP address. SIWE authentication doubles your free tier to 200 calls/day.
