Upland

Upland (Uplandme, Inc.) is a San Francisco-based Web3 metaverse company that maps virtual property onto real-world addresses, letting players buy, sell, trade and build on tokenized parcels of real cities using its in-world currency UPX and the SPARKLET token. Upland runs a public third-party Developer Program: the Upland Developers API is a documented REST contract (OpenAPI 3.0, 46 operations across Authentication, Upland User, Escrow Containers, Tournaments, Dev Shops, Application Usage and generic read-only endpoints) that lets an approved application map its own users to Upland user IDs, read a player's profile, balances, properties and NFTs, place player assets into an application-scoped escrow container, run Rumble tournaments with UPX entry fees and prize distribution, and receive eighteen documented webhook notifications. A parallel sandbox environment mirrors production. Upland also operates its own Antelope (Leap 5.0.3) appchain, whose chain RPC and Hyperion full-history API are publicly callable and documented.

Upland publishes 17 APIs on the APIs.io network, including Accounts API, Application Usage API, Authentication API, and 14 more. Tagged areas include Metaverse, Web3, Gaming, Blockchain, and NFT.

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

Upland’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, authentication, changelog, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/.

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/upland: open an issue to ask a question, or submit a pull request to add artifacts.
