Environment

Name	Required	Notes
BUYER_PRIVATE_KEY	No	Funded Base-mainnet key that signs USDC micropayments. Either this or SOLANA_BUYER_SECRET enables paid tools; the free tools (discovery, settlement risk, record verification) need neither. Secret.
X402_NETWORK	No	x402 network: 'base' (mainnet, real USDC) or 'base-sepolia' (only against a testnet deployment).
MAX_PRICE_USD	No	Hard per-call price cap in USD. Calls priced above it are refused before any payment. Default 0.05.
PREDGE_BASE_URL	No	Override the API base URL (alias: PREDGE_API_URL). Defaults to https://api.predge.io.
SOLANA_BUYER_SECRET	No	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. Secret.
X402_SOLANA_NETWORK	No	Solana network: 'solana' (mainnet) or 'solana-devnet'. Defaults to match X402_NETWORK's testnet-ness.
SOLANA_RPC_URL	No	Optional custom Solana RPC (the public mainnet-beta endpoint is rate-limited).
