🤖 x402 Protocol Revives 30-Year-Old HTTP Payment Code
**x402 protocol** is bringing the forgotten HTTP 402 "Payment Required" status code back to life after 30 years of dormancy.
**Key Features:**
- Machine-native billing standard for AI agents
- Enables per-request payments without accounts or API keys
- Supports payments for data access, compute, and API queries
- Backed by Coinbase and Cloudflare
**How it works:**
1. Agent requests paid resource
2. Server responds with HTTP 402 + payment details
3. USDC payment processed through facilitator
4. Access granted instantly upon verification
**The Graph Integration:**
The Graph's data infrastructure provides the verifiable, queryable blockchain data that x402 transactions require. Their GraphTally already implements similar microtransactions at the protocol layer.
**Combined Impact:**
- x402 = open payment rail for agents
- The Graph = open data rail for decisions
- Together = autonomous systems that think, pay, and verify
This creates a **machine-driven economy** where AI agents can autonomously transact using stablecoins across multiple chains including Base, Solana, and Polygon.
