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.

| Use AI models | Playground, account, API key, credits, first request. Everything a developer needs in one page. | how-to-use.md |
| Earn with your GPU | Run a model server, connect the open-source computing-provider, pass verification, deposit collateral, get paid per token. | become-a-provider.md |
| API reference | Every endpoint, header, limit and error code, with copy-paste examples in curl, Python, Node and Go. | swan-inference-api.md |
| How the marketplace works | Routing, the two-price model, settlement, verification and the Token Plan — for anyone who wants to know what happens behind a request. | inference-marketplace.md |

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.
