🟢search_apis(query, category, auth, free, https, ...)
Find a public API or data source for a task: use this whenever the user (or your code) needs an API, dataset or third-party service, e.g. weather, geocoding, payments, sports scores, crypto prices, jobs, LLMs. Searches 1,500+ APIs on PublicAPIs.io and returns name, description, category, link and signals (auth: none/api_key/oauth, free_tier, https). Filter with auth="none" for APIs that need no key, free=true, https=true.
