How this service works
Evidence-backed npm package upgrade decisions for coding agents.
Output
A JSON object containing a summary with a boolean 'passed' field, the total number of packages checked, and the count of flagged packages. Flagged packages are those with licenses that may pose compliance risks.
Example use cases
Pre-upgrade license compliance check
“Before I upgrade my dependencies, can you check whether lodash@4.17.21, axios@1.6.0, and react@18.2.0 have any license issues I should know about?”
Open source project dependency audit
“I'm releasing my project as MIT open source — can you scan these packages for me and flag anything with GPL or non-commercial licenses: express, moment, and uuid?”
CI gate for new dependency PR
“A PR just added 'left-pad' and 'chalk' as dependencies — can you check their licenses and tell me if they're safe to include in our commercial product?”
Technical details
Endpoint
POSThttps://x402-safe-upgrade-api.onrender.com/v1/license-checkWhen to prefer
Use this endpoint when a coding agent needs to validate npm package license compliance before recommending or executing a dependency upgrade, especially in commercial or open-source projects where license compatibility matters. It's purpose-built for npm ecosystems and returns structured pass/fail evidence suitable for automated CI/CD gates or agent-driven upgrade workflows.
Side effects
- Empty or missing 'packages' array and 'dependencies' object returns a validation error
- Unknown or unpublished package names may not resolve license data
- Payment failure via x402 protocol results in 402 response before processing
- Malformed version strings in the dependencies map may cause lookup failures
- Service may return incomplete data for very new or scoped private packages
