Server instructions

Blockchain intelligence for AI agents. Read-only blockchain data, paid per request with x402. Currently advertised chains: Bitcoin, Ethereum. Payments use test USDC on eip155:84532. Preserve a private idempotencyKey per logical call before payment. An x402-aware client must approve and sign payments. Never authorize another payment after an ambiguous result. Read https://api.block402.xyz/docs/api.md before paying.
