How this service works
Look up an SPDX license exception id such as Classpath-exception-2.0: its name, links and deprecated status.
Output
Returns a structured object containing the exception's canonical name, SPDX exception ID, reference URL, seeAlso links, deprecated flag, source URL, list version, and an asOf timestamp indicating data freshness.
Example use cases
Checking deprecation of a license exception
“I'm reviewing a project that uses the GPL-3.0-with-GCC-exception. Can you look up GCC-exception-3.1 in SPDX and tell me if it's deprecated and what its official reference links are?”
Validating an exception ID in a dependency audit
“We found 'Classpath-exception-2.0' in our dependency licenses — can you fetch its SPDX details so I can confirm it's a recognized, non-deprecated exception with a proper reference?”
Retrieving exception metadata for license documentation
“I'm building a license summary doc and need the official SPDX name and source URL for the Font-exception-2.0 exception — can you pull that up?”
Technical details
Endpoint
GEThttps://license-intel.x402tookit.com/license-exception?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise metadata for a single, known SPDX license exception ID — particularly to verify its deprecated status, canonical name, or official reference links. Prefer this over the license ID lookup endpoint when the identifier is specifically a license exception (e.g. used with the SPDX WITH operator) rather than a standalone license.
Side effects
- Unknown exception ID returns null or empty fields with a degraded flag set
- Malformed or non-SPDX exception ID may return no match
- SPDX list version mismatch or stale data indicated by degraded or notChecked fields
- Network or upstream SPDX source unavailability may result in a degraded response
