Blackcart

Blackcart is a Try Before You Buy (TBYB) platform for ecommerce merchants that lets online shoppers order products, receive them at home, and pay only for what they keep during a trial window. The platform pairs a proprietary fraud and AI order-decisioning engine with storefront integrations for Shopify, Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, WordPress, and custom storefronts, and charges merchants a revenue share on kept items rather than upfront or integration fees. Founded circa 2019 and backed by a 2021 US$8.8M Series A (investors include 500 Global), Blackcart exposed a Beta REST API (order cancellation, refunds, product/store endpoints) documented on Stoplight. As of this enrichment pass its primary domains (blackcart.com and its *.blackcart.com subdomains) return Fastly "unknown domain" errors and blackcart.co serves only a JavaScript redirect shell, indicating the public product and developer surface is offline or the company has wound down.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

Blackcart is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.

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. From those artifacts we compute the Kin Score — Blackcart scores 8.3/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Properties that don't map to a standard resource type

Blackcart is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
