How this service works
Check software license compatibility for a given use case
Output
Returns a compatibility verdict indicating whether the provided SPDX licenses are mutually compatible and suitable for the given use case, along with any conflicts or restrictions between the licenses.
Example use cases
Automated license check for CI/CD pipeline
“I'm setting up automated compliance checks in our CI/CD pipeline. Can you check if the licenses in our project dependencies are compatible for commercial use? We have MIT, Apache-2.0, and some BSD-3-Clause components that I need to verify before we deploy.”
Open-source project license compatibility validation
“We're starting an open-source project and want to ensure our dependencies work well together. Can you verify if MIT, LGPL-2.1, and MPL-2.0 licenses are compatible with each other? We plan to keep it fully open-source and want to make sure there are no conflicts.”
Internal tool dependency compliance review
“We're building an internal tool using several open-source libraries with different licenses. Can you check if AGPL-3.0, Apache-2.0, and MIT are compatible for internal use only? I want to make sure we're compliant before we finalize our dependencies.”
Technical details
Endpoint
GEThttps://api.strale.io/x402/license-compatibility-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify software license compatibility across 30+ SPDX licenses for a specific use case (commercial, SaaS, open-source, internal). Prefer this over manual legal review for quick automated compliance checks during dependency auditing, CI/CD pipelines, or when building software that combines multiple open-source components.
Side effects
- Unknown or non-SPDX license identifier returns an error or unsupported license response
- Missing required 'licenses' query parameter returns a 400 bad request
- Only one license provided may return trivially compatible result without conflict analysis
- Invalid use_case value may be ignored or return an error
- Payment failure or insufficient USDC returns 402 Payment Required
