Put your own value in place of <SPEND_CAP_USD> (Total USD this server may spend from your wallet before it stops. Required: the server refuses to start without it. About 100 lookups per dollar). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: PRIVATE_KEY (Private key of a Base mainnet wallet holding a little USDC. No ETH needed: x402 payments are settled by a facilitator, so the wallet signs off-chain and pays no gas. Use PRIVATE_KEY_FILE instead to keep the key out of your client config), PRIVATE_KEY_FILE (Path to a file containing the wallet private key. Preferred over PRIVATE_KEY. Set exactly one of the two), MAX_PRICE_USD_PER_CALL (Most this server will pay for a single lookup. Defaults to 0.01, the advertised price. A 402 asking for more than this is refused rather than paid), REQUEST_TIMEOUT_MS (How long to wait for the API, in milliseconds. 1000 to 300000, default 45000).
