How do I call another micro-service from my micro-service? - apollo

Question

This might sound a little odd, but I'm facing a situation where I have a micro-service that assembles some pricing logic, but for that, it needs a bunch of information that another micro-service provides.
I believe I have two options: (1) grab all the data I need from the database and ignore the GraphQL work that was done in this other micro-service or (2) somehow hit this other micro-service from within my current service and get the data I need.
How would someone accomplish (2)?
I have no clear path of how to get that done without creating a mess.
I imagine that turning my pricing micro-service into a small client could work, but I'm just not sure if that's bad practice.

After much consideration and reading the answers I got here, I decided to turn my micro-service into a mini-client by using apollo-client.
In short, I have something like this:
import { ApolloClient } from 'apollo-client';
import { InMemoryCache } from 'apollo-cache-inmemory';
import { HttpLink } from 'apollo-link-http';
// Instantiate required constructor fields
const cache = new InMemoryCache();
const link = new HttpLink({
uri: 'http://localhost:3000/graphql',
});
const client = new ApolloClient({
// Provide required constructor fields
cache: cache,
link: link,
});
export default client;
That HttpLink is the federated schema, so I can call it from my resolver or anywhere else like this:
const query = gql`
query {
something(uid: "${uid}") {
field1
field2
field3
anotherThing {
field1
field2
}
}
}
`;
const response = await dataSources.client.query({query});
