SingularityNET

SingularityNET is a decentralized AI services marketplace built on blockchain. Developers can publish AI services to the network and consumers can access them using the ASI (FET) token. The platform uses a daemon (snetd) that exposes AI applications as gRPC APIs accessible through the SingularityNET Network, with a REST API for marketplace interaction and service discovery.

SingularityNET publishes 5 API contracts indexed on the APIs.io network, including Channels API, Organizations API, Service Groups API, and 2 more. Tagged areas include Artificial Intelligence, Blockchain, Decentralized AI, AI Marketplace, and Web3.

The SingularityNET catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

SingularityNET’s developer surface includes engineering blog, documentation, and 15 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/.

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.
