payload402.edgebytenet.workers.dev/license/check

npm license check before install — call immediately before npm install, yarn add, or pnpm add. Returns npm-declared license, SPDX id, and permissive-default compatible (yes | no | unknown) so the agent can proceed, swap package, or escalate. Not SBOM, not legal advice. Free taste: GET /license/check/preview (same JSON, $0), then pay GET /license/check or MCP check_npm_license for the package you will install. Many packages: GET /license/lockfile/preview then /license/lockfile.
