Cratejoy

Cratejoy is a subscription-box commerce platform and marketplace (a CRV and Y Combinator company) that lets independent creators launch, sell, and manage recurring subscription boxes and one-time products. It exposes two public REST APIs: a Merchant API (https://api.cratejoy.com/v1/) covering customers, orders, subscriptions, shipments, products, inventory, carts, transactions, and webhooks; and a front-end Store API for reading and writing customer-scoped data from a storefront theme. Resources are JSON, authenticated with HTTP Basic credentials, paginated, filterable with double-underscore operators, and rate-limited with Retry-After.

Cratejoy publishes 2 APIs on the APIs.io network. Tagged areas include Company, E-Commerce, Subscription, Subscription Boxes, and Marketplace.

The Cratejoy catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Cratejoy’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 17 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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/cratejoy: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
