Environment / auth

TRUSTAGENT_URL
Service to query. Defaults to the hosted deployment.
TRUSTAGENT_WALLET_KEY
secret
Private key of a funded Base wallet. Enables the four paid tools, which settle per call in USDC over x402. Omit to run the free tools only — they need no wallet. Requires the optional peer dependency x402-fetch.
TRUSTAGENT_MAX_PER_CALL_USD
Refuse any single paid call above this amount.
TRUSTAGENT_MAX_SESSION_USD
Total spend ceiling across all paid calls in one session. A model looping on a retry is the realistic failure, and a per-call limit does not catch it.
