Industrial packaging is sold through sales, distribution and negotiated contracts, and the one place a price list exists — "current and future pricing" and downloadable price lists inside the Greif+ customer portal — requires an authenticated customer account: plus.greif.com redirects every anonymous request to /SignIn. There is no developer plan, subscription tier, quota or overage published anywhere on a Greif host, and no developer.greif.com / api.greif.com hostname exists to carry one. An honest zero, not a gap in the probe. The one API Greif does serve — the WordPress REST API on the corporate site — is free, anonymous and undocumented, with no plan, quota or commercial terms attached to it at all. evidence: - url: https://www.greif.com/greif-plus/ status: 200 finding: >- Greif+ marketing page lists portal features (orders, forecasts, datasheets, pricing, invoices) and links to the portal sign-in; no plans, tiers or prices are shown - url: https://plus.greif.com/ status: 200 finding: 302 to /SignIn — the portal (and any price list inside it) is customer-authenticated - url: https://developer.greif.com status: 0 finding: NXDOMAIN — no developer portal hostname exists to publish plans on
