How this service works
Look up an SPDX license id: name, OSI and FSF status, deprecated flag, links, and plain-language permissions and duties.
Output
Returns a structured object containing the license's official name, SPDX ID, OSI-approved and FSF-libre boolean flags, deprecated flag, reference URL, seeAlso links, license family, plain-language permissions, conditions, limitations, a summary, overview, verdict, and metadata such as list version and data freshness timestamp.
Example use cases
Dependency license compliance check
“I'm auditing our project dependencies and found it uses the LGPL-2.1 license — can you look that up and tell me whether it's OSI-approved, FSF-libre, deprecated, and summarize what it requires us to do when we distribute software?”
Open source license selection
“I'm choosing a license for my new project and considering MPL-2.0 — can you pull up its SPDX details and explain what it permits, what conditions it imposes, and whether it's approved by OSI?”
Legal team license briefing
“Our legal team needs a quick briefing on the EUPL-1.2 license — look it up and give me its full official name, OSI and FSF status, any deprecation notice, and the plain-English summary of permissions and duties.”
Technical details
Endpoint
GEThttps://license-intel.x402tookit.com/license-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need rich, structured metadata for a single known SPDX license ID — including OSI/FSF status, deprecation state, plain-language permissions and duties, and reference links. Prefer it over the search endpoint when you already know the exact SPDX identifier. For comparing two licenses, use the comparison endpoint; for classifying multiple licenses by strength, use the classify endpoint.
Side effects
- Unknown SPDX ID returns null or empty fields with a degraded flag
- Deprecated license IDs may return data but with deprecated=true and a note suggesting modern alternatives
- Malformed or missing 'id' query parameter results in a 400-level error
- Service unavailability causes a payment-accepted but empty/error response
