Starting today, agents can autonomously access blockchain data across 100+ networks, paying in @USDC via @coinbase's x402 standard. No human required. 🧵

The flow: 1. Agent authenticates via SIWE with its onchain wallet 2. Calls our agentic gateway with an API request 3. Gateway returns an HTTP 402 with payment instructions 4. Agent pays in USDC on @base via x402

Once paid, subsequent requests work automatically until the balance runs out. When it does, the agent tops up on its own. Start with as little as $1. No contracts or approval process.

Autonomous agents are managing DeFi positions, monitoring prices, and running complex workflows across chains. When an agent needs onchain state at 3 AM, it shouldn't wait for someone to unlock the door. We built this so agents are first-class users of blockchain infra.

Available at launch: → Core RPC across all supported chains → NFT APIs for ownership and metadata → Portfolio APIs for multi-chain wallet views → Prices APIs for spot and historical token pricing More chains coming soon.

We're also publishing Alchemy Skills: structured, machine-readable reference docs that help AI agents discover and use every Alchemy product. Developer docs designed for agents instead of humans. Start building:
