x402 MCP web parser: URLs to Markdown for agents. USDC on Base, Polygon, Arbitrum, Ethereum.

Schedule a future HTTP action or callback for autonomous agents. At a delay or a set time, either (a) execute an HTTP request you specify (method/url/headers/body) and capture the response for retrieval, or (b) deliver a JSON payload to your HTTPS callback URL (push) / hold it for polling. Lets agent loops defer and fire web actions without staying online or busy-polling.
