About
The Lightchain SDK (@lightchainai/sdk on npm) is Lightchain Protocol's TypeScript client for the LightChain AI Developer API, which its README describes as OpenAI-compatible. It runs an API key against the selected network and, given a wallet, can top up the prepaid balance automatically when the API answers 402, or sign a payment for each call in an experimental mode. API keys are created on the Developer page of the Lightchain chat. The current npm release is 0.1.0-alpha.2. LightApps has not audited the payment logic.
Lightchain SDK is listed on LightApps as part of the growing Lightchain application ecosystem. LightApps is an independent catalog and is not an official Lightchain product listing.
