Epos Now

Epos Now is a cloud-based point of sale (POS) platform for retail and hospitality businesses, pairing countertop and mobile till hardware with a cloud Back Office for products, inventory, customers, staff, reporting, and payments. The EposNow HQ REST API lets developers programmatically read and write that cloud data - products, categories, transactions (sales), customers, stock, tax rates, and devices - using per-device Basic authentication, with Webhooks for event notifications. API access is enabled per registered API Device from the Back Office and is available through the Epos Now AppStore rather than sold as a standalone metered API product.

Epos Now publishes 6 API contracts indexed on the APIs.io network, including Categories API, Customers API, Devices API, and 3 more. Tagged areas include Point-of-Sale, Retail, Hospitality, Payments, and Inventory.

Epos Now’s developer surface includes engineering blog, pricing, authentication, documentation, and 7 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/.

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.

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
MACH & Headless Commerce	undeclared	-	-	-
UK G-Cloud Suppliers (UK public-sector cloud procurement)	undeclared	-	-	-

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.
