No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/nadac_history for the schema, then POST the same URL with its arguments for the data.

Weekly price history for one drug NDC — how the pharmacy acquisition cost (NADAC) moved over time. Use for “has the price of this generic gone up”, shortage-driven price spikes, or generic erosion after a patent expiry. Returns one row per published week, oldest to newest, with the pricing unit and the percentage change across the window. Keyless.

Parameters

`ndc`	string	yes	National Drug Code in any common format (11-digit, dashed 5-4-2, or 10-digit).
`weeks`	number	no	How many recent weekly observations to return, 1–260 (default 26).
