§02 Environment variables

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.
