Give each its own PIPRAIL_<CHAIN>_KEY (+ optional PIPRAIL_<CHAIN>_RPC_URL). The agent pays whichever chain a 402 asks for — the first listed that can settle — under one shared budget. · PIPRAIL_EVENT_LOG=Mirror payment events (settled / declined / budget-threshold) as one-line JSON to 'stderr' or a file path — the operator's notification stream. Default: off. · PIPRAIL_MAX_AMOUNT=Max spend per single payment, in token units (default: 0.10). · PIPRAIL_MAX_PAYMENTS=Lifetime cap on the NUMBER of payments, across every chain + token (e.g. 100). · PIPRAIL_MAX_PAYMENTS_PER_WINDOW=Cap on the number of payments within PIPRAIL_WINDOW_SECONDS (a rolling rate limit; set PIPRAIL_WINDOW_SECONDS too). · PIPRAIL_MAX_TOTAL=Lifetime spend cap per token, in token units (default: 10.00). · PIPRAIL_MAX_TOTAL_DENOM=Cross-token GRAND TOTAL: one spend cap per denomination across every stablecoin and chain, e.g. USD:20.00,EUR:5.00. Not a price oracle — sums tokens of the same unit, each counted 1:1. Native coins are excluded. · PIPRAIL_PRIVATE_KEY=Your wallet's private key/seed for the chosen chain. Optional: omit it to run read-only (discover/quote/register/budget/guide); set it to let the agent pay. Stays on your machine; the spend policy caps every payment. · PIPRAIL_SCHEMES=Comma-separated payment schemes to settle (default: onchain-proof). Add 'exact' (onchain-proof,exact) to also pay standard x402 servers GASLESS on EVM + Solana (method auto-selected). Add 'upto' to also pay metered x402 servers on EVM (Permit2): sign a MAX, the server settles the actual <= max. · PIPRAIL_SPEND_LOG=Path to a local append-only spend log. When set, the budget (lifetime, grand total, counts) SURVIVES a restart — hydrated from this file. No backend; you own the file. · PIPRAIL_TOKENS=Comma-separated allowed token symbols, plus the alias 'native' for the chain's coin (default: USDC). · PIPRAIL_WARN_AT_FRACTION=Emit an early-warning event when spend crosses this fraction of any cap, e.g. 0.8 (80%). Needs PIPRAIL_EVENT_LOG to be visible."
