AGON_GATEWAY_BASE_URL
Optional Agon Gateway base URL. Defaults to https://gateway.agonx402.com.
AGON_SIGNER_COMMAND
Executed only by agon_gateway_auth_call after an HTTP 402: spawns once with the normalized auth-request JSON on stdin (same shape as agon_gateway_prepare_auth). Stdout must be JSON auth output (headers map, or SIWX address+signature). On Windows, npx/npm run under cmd.exe; treat AGON_SIGNER_COMMAND as untrusted if an attacker controls it.
AGON_WALLET_PROFILE
Optional Agon wallet profile hint passed to signer hooks.
AGON_PAYMENT_MAX_AMOUNT_USD
Optional x402 maximum USD amount per request.
AGON_PAYMENT_DAILY_LIMIT_USD
Optional x402 daily authorized spend limit in USD.
