How this service works
Pure-compute license-compatibility verdict, no network. Give a list of SPDX ids or one SPDX expression with AND, OR and WITH plus a target license and a distribution model, and get the matrix verdict of safe, attribution-required, copyleft-risk or incompatible with the obligation and reasons. Automated indicators, not legal advice.
Output
A JSON object containing a compatibility verdict (one of: safe, attribution-required, copyleft-risk, incompatible), the specific obligations triggered (e.g. attribution notices, source disclosure), and a human-readable explanation of why each license combination results in that verdict. Explicitly noted as automated indicators, not legal advice.
Example use cases
Example prompt
“Check whether combining MIT, Apache-2.0, and GPL-3.0 dependencies is compatible with my project licensed under GPL-3.0, distributed as SaaS — give me the verdict and any obligations I need to know about.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/license/compatWhen to prefer
Use this endpoint when you need a fast, pure-compute license compatibility check against SPDX-standardized identifiers without any network round-trips to external registries. Prefer it over manual legal review when you need automated pipeline integration, dependency auditing, or quick compatibility screening for open source projects. Ideal for CI/CD workflows, agent-based code review, or any situation where you need a structured machine-readable verdict with obligations rather than a narrative legal opinion.
Side effects
- Invalid or unrecognized SPDX identifier returns an error indicating the unknown license
- Malformed SPDX expression syntax causes a parse error response
- Missing required target_license parameter results in a 400 bad request
- Unknown distribution model value (not saas/binary/internal) triggers validation error
- Conflicting or ambiguous SPDX WITH operator usage may produce an incompatible verdict with an explanation
