AgentCore Gateway handoff

AgentCore Gateway buyers can add the Coinbase x402 Bazaar MCP server target at https://api.cdp.coinbase.com/platform/v2/x402/discovery/mcp with No Authorization.

Coinbase Bazaar MCP buyers use search_resources to discover payable resources and proxy_tool_call for the paid-call path. Listing Roast's owned MCP endpoint exposes no-spend compatibility handoffs for both tool names.

Recommended no-spend sequence: inspect /x402.json, /openapi.json, and /api/paid-usage-proof, then pay GET /api/listing-roast up to 1000 USDC units only when explicitly spending.

No-spend boundary

This page does not call a paid route. A buyer should only run the x402 command when they explicitly intend to spend USDC.
