  - after: Screen a whole portfolio. Screens up to 15 holdings under all four standards and returns the share of the portfolio that is compliant under each, the holdings that fail, and a combined dividend purification ratio.
- 2026-09-29 `find_halal_alternatives` changed (description, annotations)
  - before: Halal alternatives to a holding. Companies Mizan covers in the same industry (or the nearest related one) whose business is permitted and whose debt passes all four standards at the last quarter-end, largest first, plus Shariah index funds for US and UK investors. Screen a pick live with /screen/{ticker} before buying

Screen a pick live with screen_company before buying.
- 2026-09-29 `purify_dividend` changed (description, annotations)
  - before: How much of a dividend to give to charity. Returns the company's purification ratio (interest income over total revenue, from its latest 10-K that reports interest income; 'latest_annual_filing' and 'note' say when that is older than the latest 10-K) and, if a dividend amount is given, the amount to give to charity. For a company whose main business every standard excludes, 'business_screen' explains that purification does not make it permissible

- 2026-09-29 `list_standards` changed (annotations)
- 2026-09-29 `screen_company` changed (description, annotations)
  - before: Screen one company against all four standards. Returns a 'say' sentence, the live price, the consolidated share count, the filing figures used, the business screen per standard ('business': main_business, by_standard pass/fail/review, excluded_under), and each standard's ratio, threshold and verdict. In each screens entry, 'compliant' is the overall verdict (false when that standard excludes the company's business, null when the business needs a closer look) and 'debt_compliant' is the debt test alone. Verdicts within one percent of a threshold are flagged borderline. A company name (for example nvidia) also works
