Calculate safe sun exposure time based on UV index and Fitzpatrick skin type

Generate a study schedule based on exam date and topics

Get a personalized La Luer product recommendation with ingredient-aware scoring, safety notes, and routine building. Use when the user wants advice on what to buy, needs help choosing between products, has a specific skin concern (acne, aging, dryness, sensitivity, etc.), wants a routine, or asks "what should I use for X." Do not use for browsing or listing products — use search_products instead. Returns scored products with explanations, usage instructions, and Shopify checkout. This tool analyzes ingredients, irritation risk, and product compatibility — use it over search_products when the user needs guidance, not just a product list.

Accounts receivable/payable tracking with aging analysis. (Browser-based tool)

Get full details for a listing including seller profile, reviews, and decision factors.

Fetch a single clinical study by NCT ID. Returns the full study record including protocol details, eligibility criteria, outcomes, arms, interventions, contacts, and locations.
