⚙️ Input

Field	Type	Description
searchTerms	array	Keywords to search across registries.
packages	array	Exact packages as "platform/name" (no key needed).
platform	string	Optional. Restrict keyword search to one registry.
sort	string	Order search results (SourceRank, stars, dependents, and more).
maxItems	integer	Cap on packages returned. Free plan is limited to 10.
apiKey	string	Libraries.io API key for keyword search. A shared key ships by default.

Example 1: keyword search

{
  "searchTerms": ["http client"],
  "sort": "rank",
  "maxItems": 50
}

Example 2: exact packages

{
  "searchTerms": [],
  "packages": ["npm/react", "pypi/django", "cargo/serde"]
}

⚠️ Good to Know: keyword search uses the Libraries.io API and a shared key ships by default. Exact package lookups work without any key. The status and deprecationReason fields fill in only for deprecated or removed packages.
