typescript and trpc data validation

another noob question from me, but trying to figure out typescript. So if I have a piece of code like this in my router:

export const coinRouter = router({
  getCoin: publicProcedure
  .input(z.object({ name: z.any()}))
    .query(async ({ input }) => {
      const coin = await fetch(`https://api.coingecko.com/api/v3/coins/${input.name}`).then(res =>
      res.json());
      return coin      
    }),
});

export const coinRouter = router({
  getCoin: publicProcedure
  .input(z.object({ name: z.any()}))
    .query(async ({ input }) => {
      const coin = await fetch(`https://api.coingecko.com/api/v3/coins/${input.name}`).then(res =>
      res.json());
      return coin      
    }),
});

and the data from this api url is really long , how should I go about typing it? I am not using the whole of the data, so is there a way to pick in trpc router only the data that I'm interested in?

Use typescripts Pick type helper

But do you mean I should use it to create data from all the objects inside this json? because there are a lot, also not sure how Pick works (newbie typescripter here) to type data* sry
