Its input: ```json { "max_results": 200 } ``` Its output: ```json { "blockchains": [ { "rank": 1, "tvl_usd": 53108335050, "page_url": "https://defillama.com/chain/ethereum", "chain_name": "Ethereum", "defi_projects": 2032, "change_1d_percent": -0.1698818443182991, "change_7d_percent": -2.6204888468664813, "native_token_symbol": "ETH" }, { "rank": 2, "tvl_usd": 6421423324, "page_url": "https://defillama.com/chain/solana", "chain_name": "Solana", "defi_projects": 643, "change_1d_percent": -3.197296255971719, "change_7d_percent": -0.43208119414242924, "native_token_symbol": "SOL" }, { "rank": 3, "tvl_usd": 6219474904, "page_url": "https://defillama.com/chain/base", "chain_name": "Base", "defi_projects": 1125, "change_1d_percent": -0.7163654151087694, "change_7d_percent": -3.5663736335965126, "native_token_symbol": null } ] } ``` ## Run it From code, with a Fous API key in `FOUS_API_KEY`; the answer's `data` holds the output: ```bash curl https://api.fous.com/v1/runs \ -H "Authorization: Bearer $FOUS_API_KEY" \ -H "Content-Type: application/json" \ -d '{"method":"defillama.com/list_top_blockchains","input":{"max_results":200}}' ``` From an AI agent connected to the Fous MCP server: its `run` with the same method and input. To connect one, give it `set up https://fous.com/SKILL.md`. ## Ask your agent - Which blockchains have the most total value locked in DeFi right now? Give me the top 10. - Pull the top 50 chains ranked by TVL from DefiLlama, including their 1-day and 7-day changes. - I need a ranking of L1s and L2s by DeFi TVL with the number of protocols on each and their native token tickers. - Show me DefiLlama's chain leaderboard by locked value: the top 25 networks. - How has TVL moved over the past week across the biggest DeFi chains? List the top 100 with weekly percentage change. ## Input schema ```json { "type": "object", "properties": { "max_results": { "type": "integer", "default": 20, "maximum": 200, "minimum": 1, "description": "Maximum number of top blockchains to return, for example 20." } } } ``` ## Output schema ```json { "type": "object", "required": [ "blockchains" ], "properties": { "blockchains": { "type": "array", "items": { "type": "object", "required": [ "rank", "chain_name", "tvl_usd", "change_1d_percent", "change_7d_percent", "defi_projects", "native_token_symbol", "page_url" ], "properties": { "rank": { "type": "integer", "description": "Position in the TVL ranking, starting at 1." }, "tvl_usd": { "type": "number", "description": "Total value locked in US dollars." }, "page_url": { "type": "string", "description": "Chain details page." }, "chain_name": { "type": "string", "description": "Blockchain name." }, "defi_projects": { "type": "integer", "description": "Number of DeFi projects." }, "change_1d_percent": { "type": [ "number", "null" ], "description": "Reported one-day TVL percentage change, or null if unavailable." }, "change_7d_percent": { "type": [ "number", "null" ], "description": "Reported seven-day TVL percentage change, or null if unavailable." }, "native_token_symbol": { "type": [ "string", "null" ], "description": "Chain token symbol, or null when none is listed." } }, "additionalProperties": false }, "minItems": 1 } }, "additionalProperties": false } ``` ## See more - [DefiLlama API: Get DeFi project](https://fous.com/methods/defillama.com/get-defi-project.md): Gets a DeFi project's current TVL, 1-day and 7-day changes, chain breakdown, token information and daily TVL history from DefiLlama.
