How this service works
License of a GitHub repository: SPDX id, full name, license file path, permissive/copyleft class, plus the license's permissions, conditions and limitations lists from GitHub's license metadata. Compliance check before vendoring code. $0.01 per repo.
Output
Returns the SPDX license identifier (e.g. MIT, Apache-2.0, GPL-3.0), the full human-readable license name, the path to the license file in the repository, a permissive/copyleft classification label, and three structured lists from GitHub's license metadata: permissions granted (e.g. commercial use, modification), conditions required (e.g. include copyright), and limitations (e.g. liability, warranty).
Example use cases
Pre-vendoring compliance check
“I want to vendor the code from nickel-org/nickel.rs into our project — can you pull its GitHub license info and tell me if it's permissive or copyleft and what obligations come with it?”
Open source audit for a new dependency
“We're about to add langchain-ai/langchain as a dependency. Can you check what license it has on GitHub, get the SPDX ID, and list any conditions or limitations we need to be aware of?”
Comparing licenses across candidate libraries
“Can you look up the GitHub licenses for expressjs/express and fastify/fastify and tell me the SPDX IDs and whether they're permissive — I need to pick the one with fewer commercial restrictions?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dev/github-licenseWhen to prefer
Use this endpoint when you need structured, machine-readable license metadata for a specific GitHub repository, especially for compliance workflows before vendoring or adopting a dependency. It is preferred over scraping the GitHub UI because it returns parsed SPDX IDs, permissions/conditions/limitations lists, and a permissive-vs-copyleft classification in a single call. Choose this over generic web search when you need structured compliance data rather than a prose explanation of a license.
Side effects
- Repository not found or private — returns an error indicating the repo could not be accessed
- Repository has no detectable license file — returns null or empty license data
- Invalid or malformed repository identifier — returns a validation error
- GitHub rate limiting or API unavailability — returns a service error
- Ambiguous or custom license not recognized by GitHub's metadata — may return partial data without SPDX ID
