# Drug Acquisition Cost
> Look up weekly average acquisition costs for US outpatient drugs by NDC or exact drug description.
Look up the NADAC survey by an 11-digit NDC (dashes are removed) or an exact drug description converted to uppercase. At least one is required; NDC takes precedence when both are supplied. Reads up to 100 source rows, newest weekly as-of date first, then newest effective date, keeps the first row per NDC and returns up to limit prices. The survey refreshes weekly and publishes its own effective and as-of dates. These are pharmacy acquisition rates per unit, not retail patient prices. No match returns an empty prices list.
## Authentication
Requires x402 payment in the `payment-signature` header.
## Request Body
National Drug Code; takes precedence over description. 11 digits, with optional dashes.
Exact source drug description, matched in uppercase, for example ATORVASTATIN 20 MG TABLET. 3 to 100 characters.
Maximum number of distinct NDC prices to return. From 1 to 25. Defaults to `10`.
## Response (200 OK)
Top-level envelope: `success` (boolean) and `data` (object). All fields below are nested under `data`.
