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 4 APIs on the APIs.io network, including Channels API, Organizations API, Service Groups API, and 1 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 11 more developer resources.
