Environment / auth
  • EVM_PRIVATE_KEY
    secret

    0x private key of a DEDICATED wallet holding USDC on Base (pays per call). Paid tools return 402 without it; the free validate_cnpj tool still works.

  • SOLANA_PRIVATE_KEY
    secret

    base58 or JSON-array secret key of a DEDICATED Solana wallet holding USDC (pays per call). Configure this and/or EVM_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises.

  • SOLANA_RPC_URL

    Optional Solana RPC override used to build the payment (e.g. a Helius URL).

  • BRDATA_BASE_URL

    Base URL of a brdata Worker. Defaults to the hosted production API (https://brdata.thomenz.me).

  • X402_NETWORK

    'base' (mainnet, default) or 'base-sepolia' (testnet).
