Environment / auth

BUYER_PRIVATE_KEY
secret
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
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).
