This one needs environment variables set before it will start: BUYER_PRIVATE_KEY (Funded Base-mainnet key that signs USDC micropayments. Either this or SOLANA_BUYER_SECRET enables paid tools; the free discovery tool needs neither.), X402_NETWORK (x402 network: 'base' (mainnet, real USDC) or 'base-sepolia' (only against a testnet deployment).), MAX_PRICE_USD (Hard per-call price cap in USD. Calls priced above it are refused before any payment. Default 0.05.), PREDGE_BASE_URL (Override the API base URL. Defaults to the production deployment.), SOLANA_BUYER_SECRET (Funded Solana-mainnet key (64-number JSON array or base58) to also pay on Solana. Optional — either this or BUYER_PRIVATE_KEY enables paid tools.), X402_SOLANA_NETWORK (Solana network: 'solana' (mainnet) or 'solana-devnet'. Defaults to match X402_NETWORK's testnet-ness.), SOLANA_RPC_URL (Optional custom Solana RPC (the public mainnet-beta endpoint is rate-limited).). The author declared them in the registry entry; get the values from the project itself.
