The three most-used free tools on bindler.co as JSON endpoints: ai-act-classify (risk class, obligations, application date and fine ceiling under Regulation (EU) 2024/1689), cbam-cost (certificates and cost per tonne for one import basket, 2026 to 2034) and uae-corporate-tax (Small Business Relief, QFZP, Article 20(2)). Generated from the same code the browser tools run, so the API cannot disagree with the page. Free tier 25 calls a day, no account; $19 a month key for unlimited.

Three free browser tools for rules with a deadline. EU AI Act classifier: one system, its risk class, obligations, application date and fine ceiling, every answer cites the article; a $19 key unlocks an unlimited register and CSV. UAE Corporate Tax calculator: Small Business Relief, QFZP, the Article 20(2) computation, 0% and 9% bands. CBAM cost estimator: certificates and cost per tonne for one import basket, every year to 2034. Same logic as the Bindler workbooks, checked against worked cases.
