Environment variables
  • BUYER_PRIVATE_KEYsecretFunded Base-mainnet key that signs USDC micropayments. Either this or SOLANA_BUYER_SECRET enables paid tools; the free tools (discovery, settlement risk, verdict re-read, record verification) need neither, and PREDGE_KEY covers the calls its pilot includes.
  • PREDGE_KEYsecretOptional Predge key, sent as x-predge-key on every request. A free 30-day pilot key (predge.io/start) makes the settlement estimate and delivery verdicts free and unlocks the verdict report; a Desk key (predge.io/desk) unlocks predge_desk_config.
  • SOLANA_BUYER_SECRETsecretFunded Solana-mainnet key (64-number JSON array or base58) to also pay on Solana. Optional — either this or BUYER_PRIVATE_KEY enables paid tools.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
