Welcome

Swan Chain is a decentralized AI inference cloud. Developers call one OpenAI-compatible API and get frontier models and open-source models served by a network of independent GPU providers; providers earn per token for the requests they serve. The marketplace lives at inference.swanchain.io.

Try it in a minute. The playground runs a live model with no account. When you are ready, sign up, copy your API key, and point any OpenAI SDK at https://api.swanchain.io/v1. The live catalog shows every model with its current price, context window and how many providers are serving it right now.

Start here

Use AI models

Playground, account, API key, credits, first request. Everything a developer needs in one page.

Earn with your GPU

Run a model server, connect the open-source computing-provider, pass verification, deposit collateral, get paid per token.

API reference

Every endpoint, header, limit and error code, with copy-paste examples in curl, Python, Node and Go.

How the marketplace works

Routing, the two-price model, settlement, verification and billing — for anyone who wants to know what happens behind a request.

Build on Swan Chain

Swan Chain is also an Ethereum Layer 2 (chain ID 254). If you are deploying contracts or running a node rather than calling models, start with the network reference and the DApp developer guide.

Network info — chain IDs, RPC endpoints, explorers, token addresses

Contract addresses — L2 infrastructure and the inference contracts

Deploy a contract — first smart contract with Remix
