CopThis

CopThis is the company behind Merchbar, the official online merchandise retailer for musicians and artists, selling authenticated band and artist merch (vinyl, apparel, accessories) across thousands of artist stores. CopThis operates the Merchbar Partner API — a REST contract that merchandise and fulfillment partners implement so Merchbar can list a partner's stores and merchandise and place, track, update, and cancel orders on behalf of Merchbar customers. The API uses HTTP Basic authentication over HTTPS, a JSON envelope with a top-level data key and pagination for collections, URI-path versioning (v1), and an error envelope for 4xx/5xx responses. CopThis is a portfolio company of 500 Global.

CopThis publishes 2 APIs on the APIs.io network: Orders API and Stores API. Tagged areas include Company, Music, Merchandise, E-Commerce, and Retail.

CopThis’ developer surface includes documentation, API reference, authentication, and 14 more developer resources.

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.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/copthis: open an issue to ask a question, or submit a pull request to add artifacts.
