Implementation Reference

• index.js:276-293 (registration)

  Full registration of the dexListingsLatest tool via server.tool(), including inline description, input schema validation with Zod, and the handler function.

  server.tool("dexListingsLatest",
    "Returns a paginated list of all decentralised cryptocurrency exchanges including the latest aggregate market data.",
    {
      start: z.string().optional(),
      limit: z.string().optional(),
      sort: z.enum(['name', 'volume_24h', 'market_share', 'num_markets']).optional(),
      sort_dir: z.enum(['desc', 'asc']).optional(),
      type: z.enum(['all', 'orderbook', 'swap', 'aggregator']).optional(),
      aux: z.string().optional(),
      convert_id: z.string().optional()
    },
    async (params) => {
      return handleEndpoint(async () => {
        const data = await makeApiRequest(apiKey, '/v4/dex/listings/quotes', params)
        return formatResponse(data)
      })
    }
  )

• index.js:287-292 (handler)

  The handler executes the tool logic: invokes handleEndpoint which calls makeApiRequest to the CMC API endpoint '/v4/dex/listings/quotes' with input params and apiKey, then formats the data with formatResponse.

  async (params) => {
    return handleEndpoint(async () => {
      const data = await makeApiRequest(apiKey, '/v4/dex/listings/quotes', params)
      return formatResponse(data)
    })
  }

• index.js:278-286 (schema)

  Zod schema defining optional input parameters for pagination (start, limit), sorting (sort, sort_dir), filtering (type), and additional options (aux, convert_id).

  {
    start: z.string().optional(),
    limit: z.string().optional(),
    sort: z.enum(['name', 'volume_24h', 'market_share', 'num_markets']).optional(),
    sort_dir: z.enum(['desc', 'asc']).optional(),
    type: z.enum(['all', 'orderbook', 'swap', 'aggregator']).optional(),
    aux: z.string().optional(),
    convert_id: z.string().optional()
  },
