Environment Variables

PRIVATE_KEY(str)

Secret

Ethereum private key for write/buy tools (subscribe, unsubscribe, publish, buy_data). buy_data spends real Base-mainnet USDC — use a dedicated wallet. Not required for read-only tools.

RPC_URL(str)

RPC for the on-chain library + EIP-712 attestation layer (Arbitrum Sepolia, eip155:421614). The x402 buy rail settles USDC on Base mainnet and needs no RPC here. Defaults to Arbitrum Sepolia public RPC.
