Choosing a DeFi & DEX API

Is there a free DeFi & DEX API?

Yes. ClearTrace, Ophis and VaultVision are free to use, and DefiLlama, 1inch, DexPaprika, 0xArchive, HostDeFi and 1 other have a free tier alongside paid plans.

Which DeFi & DEX APIs work without an API key?

DefiLlama, DexPaprika, ClearTrace, dYdX, Ophis and 1 other need no key or sign-up, so you can try them with a plain request.

Can I call a DeFi & DEX API from front-end JavaScript?

DefiLlama, ClearTrace, dYdX, Ophis and VaultVision allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.

Can I use DeFi & DEX APIs in a commercial project?

1inch, DexPaprika, 0xArchive, ClearTrace and Ophis permit commercial use. MadeOnSol restricts it, for example to non-commercial or attributed use, so read the terms first.

Which DeFi & DEX APIs work with AI agents?

ClearTrace and Ophis have both an MCP server and an OpenAPI spec. 1inch, DexPaprika and 0xArchive have an MCP server, so an AI agent can call them directly. HostDeFi and MadeOnSol publish an OpenAPI spec for generating clients and tools.
