SamCart

SamCart is a checkout and e-commerce platform for selling digital products, courses, memberships, and physical goods directly to customers, built around a high-converting CheckoutOS checkout, one-click upsells, subscriptions, and a courses/members area. The SamCart Public API (v1) is a REST API at https://api.samcart.com/v1 that gives programmatic read access to a marketplace's orders, products, customers, subscriptions, charges, and refunds, plus write actions to cancel or schedule cancellation of subscriptions, refund charges, and update order custom fields. Authentication is via an sc-api API key header, and API access is provisioned by the SamCart Support team rather than fully self-serve.

SamCart publishes 6 API contracts indexed on the APIs.io network, including Charges API, Customers API, Orders API, and 3 more. Tagged areas include E-Commerce, Checkout, Payments, Subscription, and Digital Products.

The SamCart catalog on APIs.io includes 1 Spectral governance ruleset.

SamCart’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Stripe App Marketplace and Partner Ecosystem (builders on Stripe)	standard	10.1	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 4

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
