description: The Cart.com Online Store API (formerly the AmeriCommerce REST API) is a JSON REST API scoped to a single merchant
storefront domain. It exposes 136 paths and 262 operations across catalog (products, variants, categories, attributes,
inventory, pricing), orders (carts, cart items, orders, order items, payments, shipments, quotes, subscriptions), people
(customers, addresses, profiles, users), content (blogs, pages, links), marketing (adcodes, coupons, discounts, gift certificates,
mailing lists), settings (payment methods, shipping providers, tax rates, warehouses, store locations) and system resources.
It is HTTPS-only, uses snake_case JSON, ISO 8601 datetimes, and a shared query syntax for filtering, paging, sorting,
field selection and nested-resource expansion.

ⓘWhere this information came from
This is an independent, third-party profile of Cart.com, 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.
