Shippo API
Shippo is API-first: a public REST API with docs at docs.goshippo.com and official libraries in seven languages. The API Starter plan is self-serve and free for 30 labels a month, then $0.07 per label with a la carte add-ons. Webhooks cover tracking, transactions, and batch purchases.

Shippo scores A on Supergood's API Report Card. Shippo is API-first: a public REST API with docs at docs.goshippo.com and official libraries in seven languages. The API Starter plan is self-serve and free for 30 labels a month, then $0.07 per label with a la carte add-ons. Webhooks cover tracking, transactions, and batch purchases.
Shippo has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Shippo is a multi-carrier shipping API and dashboard that abstracts USPS, UPS, FedEx, DHL Express, Canada Post, Royal Mail, and 40+ other regional and international carriers behind a single REST interface.
Primary vertical: Fleet / Trucking / Logistics, specifically the parcel-shipping infrastructure layer for ecommerce. An ecommerce platform integrates Shippo at checkout and fulfillment: at checkout, the storefront POSTs to /shipments with origin, destination, and parcel dimensions to receive a list of carrier+service rates rendered as live options to the shopper; once an order is placed, the backend POSTs to /transactions with the chosen rate ID to buy the label and receives a PDF/PNG/ZPL label URL plus a tracking number.
Very high inside developer-facing shipping infrastructure. Shippo is consistently named as one of the top two or three multi-carrier shipping APIs in every comparison roundup (alongside EasyPost and ShipEngine/ShipStation).
Shippo is the system of record for shipping labels (each label is a paid transaction with a real-world physical-mail counterpart that cannot be undone once printed and scanned), carrier rate quotes presented to end consumers at checkout (a stale or wrong rate becomes a direct margin loss), address validation results that decide whether an order ships at all, customs declarations on international shipments (a wrong HS code or value triggers customs holds and chargebacks), and track_updated webhook events that drive customer-facing order-status emails and SMS.
Shippo was founded in 2013 in San Francisco by Laura Behrens Wu and Simon Kreuz after pivoting from an online-store concept, and is now ~13 years old.
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.
Shippo scores GOOD on MCP availability. Shippo hosts an official remote MCP server at mcp.shippo.com with per-user OAuth over streamable HTTP, documented alongside agent skills and client plugins in the goshippo/ai GitHub repo. The repo is actively maintained with connection guidance for Claude and other MCP clients.
Yes. Shippo publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
