How this service works
Check a list of license ids against SPDX: current, deprecated or unknown, with the modern GNU -only / -or-later form.
Output
Returns a per-ID breakdown with deprecation status (current, deprecated, or unknown), canonical SPDX ID, and suggested modern replacement (e.g. GPL-2.0-only or GPL-2.0-or-later) for each queried license. Also provides an overall verdict, summary, deprecated count, unknown count, SPDX list version and date, source URL, and any IDs that could not be checked.
Example use cases
Pre-release license audit for OSS package
“Before I publish my library, can you check all the licenses I'm using — GPL-2.0, LGPL-2.1, MIT, Apache-2.0, and BSD-2-Clause — and tell me if any are deprecated in the SPDX list and what the modern versions are?”
CI pipeline license compliance gate
“I need to validate this set of license IDs from our dependency scanner against SPDX to catch any deprecated or unknown ones before merging: GPL-3.0, AGPL-3.0, MIT, ISC, CC-BY-4.0, and Zlib.”
Modernizing legacy GNU license references
“Our codebase uses old GNU license identifiers like GPL-2.0 and LGPL-2.1 — can you check if those are deprecated in SPDX and tell me the correct modern -only or -or-later forms I should switch to?”
Technical details
Endpoint
GEThttps://license-intel.x402tookit.com/deprecated-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to batch-validate a known list of SPDX license identifiers for deprecation status and want modern GNU replacement suggestions. Prefer it over the single-ID lookup endpoint when processing multiple licenses at once (up to 50), and over the expression validator when working with individual flat IDs rather than compound SPDX expressions.
Side effects
- More than 50 IDs submitted — excess IDs may appear in notChecked array
- Malformed or empty ids parameter — likely returns an error or empty results
- SPDX list temporarily unavailable — degraded flag set to true with partial or no results
- Network timeout or upstream API outage — service may return error response
