Url2md

Host a copy with our keys and logs.

• URL2MD_PRIVATE_KEY_FILE — Path to a file holding the 0x-prefixed private key of a wallet with USDC on Base. Preferred over URL2MD_PRIVATE_KEY: a path is not a secret, and a key on a command line is visible to every process on the machine. One of the two key variables is required.
• URL2MD_PRIVATE_KEY — The key itself: 0x followed by 64 hex characters. Use URL2MD_PRIVATE_KEY_FILE instead where you can. One of the two key variables is required.
• URL2MD_MAX_PRICE_USD — The most this server will commit for one call, in USD, across every payment round of that call. A tolled page takes two rounds and this ceiling covers both.
• URL2MD_MAX_SPEND_USD — The most this server will commit in total for as long as the process runs. Restarting resets it.
• URL2MD_BASE_URL — The url2md deployment to call. Must be https (only a loopback address may be plain http), because this is the origin every 402 is checked against.
• URL2MD_TIMEOUT_MS — How long to wait for one conversion, in milliseconds. The default covers the service's own worst case: 20 s of fetching plus 55 s of headless render. Do not lower it to 30 s — that is the navigation timeout inside the browser, and on a page that needed a browser your payment has already settled by the time the render starts.
