How this service works
CRAN R package metadata (crandb JSON mirror of CRAN, public, no key): name, version, title, description, license, maintainer, publication date, dependencies and CRAN page link. Unknown packages return 404.
Output
Returns a JSON object with the package's name, current version, title, full description, license type, maintainer name/email, publication date, list of dependencies, and a link to its CRAN page. Returns a 404 error if the package name is not found on CRAN.
Example use cases
Checking R package version before install
“What's the latest version of the data.table package on CRAN, and when was it last published?”
Auditing R package license for compliance
“I need to know what license the caret R package uses — can you pull its CRAN metadata for me?”
Exploring R package dependencies
“Can you fetch the CRAN info for the Seurat package and list all its dependencies so I can plan my R environment setup?”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/search/cran-r-packages?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured metadata for a specific, known CRAN R package by exact name. It is ideal for programmatic lookups of version, license, maintainer, and dependency information without needing a CRAN API key. Prefer this over web scraping CRAN pages or parsing DESCRIPTION files manually.
Side effects
- 404 returned for unknown or misspelled package names
- Package exists on CRAN but crandb mirror may lag behind very recent submissions
- No results for archived/removed packages that are no longer on CRAN
- Exact package name required — partial or fuzzy names will not match
