Frequently asked questions
Ryerson scores F on Supergood's API Report Card. Ryerson sells metals through a logged in customer portal with no public API and no developer documentation. The only probed API host returns an Incapsula 503, and machine exchange happens through EDI arranged with a Ryerson contact.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Ryerson is a metals service center and value added processor that sells, processes and distributes carbon steel, stainless steel and aluminum products.
Manufacturing, specifically metals distribution. Ryerson serves industrial buyers, OEMs, fabricators and contract manufacturers that purchase processed metal as a production input. Buyers log into ryerson.com with an approved account to search the catalog and stock list, check availability, build a cart, place orders, follow shipment status, pull mill test documents and settle invoices.
Ryerson is described in public sources as a leading value added processor and distributor of metals with operations across the United States, Canada, Mexico, China and Brazil, giving it broad reach among industrial buyers even though no verified public customer count appears in the sourced material.
The portal and the EDI channel hold the buyer side record of metals procurement: account and contact records, quotes, purchase orders and order history, line level product and specification data drawn from the catalog and stock list, pricing and terms tied to the account, shipment and delivery status, mill test reports and certification documents, and invoices with payment status.
The commerce site is a modern web application: probes of the homepage return 200 behind a current stack, and research surfaced Azure hosted development and QA environments plus internal catalog, cart and account endpoints, which indicates active in house development.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. There is no official Ryerson MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Ryerson doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
