California manufacturer disclosures of a prescription drug’s Wholesale Acquisition Cost (WAC — the published list price before rebates/discounts) going UP. Required by California law (SB 17/AB 265) whenever a drug’s WAC exceeds $40 for a course of therapy AND the increase exceeds the statutory cumulative threshold; filed with HCAI’s Cost Transparency Rx (CTRx) program. Search by drug name/fragment, manufacturer, or NDC, optionally pinned to one report year (2019-present; omit to search every year). Returns each increase’s amount, the WAC after the increase, and whether the record comes from the still-open current year or a closed annual archive. This is the LIST price a manufacturer sets, not what any payer or pharmacy actually pays — for that, see the drug-prices pack’s nadac_price/asp_payment_limit tools. California-only: see the pack README for which other states publish this and in what form. Keyless.

Parameters

Name	Type	Required	Description
`drug`	string	no	Drug name or fragment, e.g. “Humira”, “insulin glargine”, matched against the drug product description.
`manufacturer`	string	no	Manufacturer name or fragment, e.g. “AbbVie”, “Novo Nordisk”.
`ndc`	string	no	National Drug Code, any common format.
`year`	string	no	Report year, “2019”..“2026”. Omit to search every available year (recommended for a single drug/manufacturer/NDC lookup).
`limit`	number	no	Max records to return, 1-100 (default 25).
