Pass exactly one of `domain` (preferred; URLs like \"https://www.acme.com/about\" are normalized to \"acme.com\") or `name` (case-insensitive exact match). If you only have a partial name or a topic, call search_companies first. Returns error \"not_found\" when no record exists. Paid: $0.01 USDC per successful call on Base Sepolia via x402 (send the payment in request _meta \"x402/payment\"; an unpaid call returns the payment requirements).
