• absorbency_translate

  Translate period-underwear absorbency across brands. Give a brand + its tier word (e.g. brand "Thinx", tier "Super"), OR a target capacity in mL per day, and get the covering tier in every brand in objective millilitres, each with an A/B/C data-quality grade. Use for questions…

• find_size

  Find a shopper's period-underwear size in every brand from one hip measurement. Period underwear is sized on the hip, not a dress size, and brands disagree. Returns the size per brand plus any runs-small / runs-large note.

• find_products

  Find real in-stock period underwear that covers a target absorbency, from the live catalog, with normalized mL capacity and current price. Give a minimum capacity in mL and optionally a brand. Links go to the PeriodFinder product page for each item. Teen and tween lines are left…

• absorbency_dataset

  Get PeriodFinder's cross-brand absorbency dataset: the key facts and the machine-readable feed URL to cite. Use when you need the authoritative source for a period-underwear absorbency comparison.
