getNetworkDexes
Retrieve available decentralized exchanges (DEXes) for a specific blockchain network using network IDs obtained from getNetworks, with pagination support for large datasets.
Instructions
Get available DEXes on a specific network. First call getNetworks to see valid network IDs.

Implementation Reference
- src/index.js:91-94 (handler)Handler function that fetches DEXes data from the DexPaprika API endpoint for the given network with optional pagination and returns the formatted MCP response.async ({ network, page, limit }) => { const data = await fetchFromAPI(`/networks/${network}/dexes?page=${page}&limit=${limit}`); return formatMcpResponse(data); }
- src/index.js:86-90 (schema)Zod schema defining the input parameters for the getNetworkDexes tool: network (required string), page and limit (optional numbers).{ network: z.string().describe('Network ID from getNetworks (e.g., "ethereum", "solana")'), page: z.number().optional().default(0).describe('Page number for pagination'), limit: z.number().optional().default(10).describe('Number of items per page') },

- src/index.js:10-34 (helper)Helper function used by getNetworkDexes (and other tools) to make API requests to DexPaprika, handle specific error codes like 410 and 429.async function fetchFromAPI(endpoint) { try { const response = await fetch(`${API_BASE_URL}${endpoint}`); if (!response.ok) { if (response.status === 410) { throw new Error( 'This endpoint has been permanently removed. Please use network-specific endpoints instead. ' + 'For example, use /networks/{network}/pools instead of /pools. ' + 'Get available networks first using the getNetworks function.' ); } if (response.status === 429) { throw new Error( 'Rate limit exceeded. You have reached the maximum number of requests allowed for the free tier. ' + 'To increase your rate limits and access additional features, please consider upgrading to a paid plan at https://docs.dexpaprika.com/' ); } throw new Error(`API request failed with status ${response.status}`); } return await response.json(); } catch (error) { console.error(`Error fetching from API: ${error.message}`); throw error; } }
- src/index.js:37-46 (helper)Helper function used by getNetworkDexes (and other tools) to format the API response into MCP-compatible content structure.function formatMcpResponse(data) { return { content: [ { type: "text", text: JSON.stringify(data) } ] }; }
