$npx -y x402-bazaar-mcp@0.3.0 X402_CREDIT_TOKEN · secret — Prepaid credit token (ck_…) from the buy-credits service. Sent as the x-credit-token header; each call debits your balance. No wallet or signing needed. Recommended paid mode. Buyable with USDC on Base, or with USDC/USDT/NEAR on NEAR at https://402.com.tr/credits.
AGENT_PRIVATE_KEY · secret — Hex private key of a Base wallet holding USDC. Used locally to sign x402 payments — never sent anywhere. Use a dedicated low-balance wallet. Optional: without it (and without a credit token) the server runs on the free tier.
X402_BAZAAR_CATALOG — Override the catalog URL (default https://402.com.tr/api/catalog).
