Check the StackScan credit balance. Free - does not consume a credit. Call this before a batch of lookups so you know how many you can afford.

Given a domain, return the company behind it: name, industry, city, country, address and LinkedIn URL. Use this when asked who owns or operates a website, or to enrich a domain into firmographics. Costs 1 credit.

Given a domain, list the technologies detected on it (analytics, hosting, ecommerce platform, frameworks and so on), each with its category and how many sites overall use it. Use this to answer 'what is this site built with?'. Costs 1 credit.

Given a technology name, return how widely it is used and its top countries by adoption. Use this to size a market or compare platforms, e.g. 'how many sites run Shopify, and where?'. Costs 1 credit.

Look up the companies behind up to 20 domains in ONE call, returned as a compact table. Prefer this over repeated lookup_company calls whenever you have several domains in hand - it is one request instead of many, and costs the same per resolved domain. Duplicates and www. variants collapse and are charged once. Costs 1 credit per domain that HAS data; misses and malformed domains are free.
