Sears Holdings
Sears Holdings was the American holding company behind the Sears and Kmart department store chains. It filed for Chapter 11 in October 2018 and its retail operations were acquired in 2019 by Transform Holdco LLC, which trades as Transformco (Transform SR Brands LLC), the entity that operates Sears.com, Kmart.com and ShopYourWay.com today. The live developer surface carried forward from that estate is the Sears Marketplace Seller API — a versioned XML-over-HTTPS integration for third-party sellers covering catalog and item management, item class and attribute libraries, inventory, pricing, purchase order retrieval, order cancellations, returns and partial or full refunds, ASN and shipment updates, order prep time, installation service items, and remittance, removed-item, content-match and processing reports. Every API is published with a downloadable XSD and a sample XML document, both fetchable without credentials from seller.marketplace.sears.com, and calls are signed with an HMAC-SHA256 authorization header rather than OAuth. There is no OpenAPI, GraphQL, MCP server or A2A agent card on any Sears, Kmart or Transformco host.
API Evangelist profiles Sears Holdings the way a machine reads it — 5 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
How we profile Sears Holdings
Each block below is one kind of artifact we hold for Sears Holdings. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Sears Marketplace Seller API
Versioned XML-over-HTTPS API for third-party sellers on Sears Marketplace (Sears.com, Kmart.com, ShopYourWay.com). GET calls export purchase orders, inventory, item classes, att...
Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

The organization behind the API
← All providers · Data indexed from github.com/api-evangelist/sears-holdings · machine-readable index on apis.io
This is an independent, third-party profile of Sears Holdings, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
