Is my anthropic API (free version) really out of credits or is there a different underlying issue, when I prepare a project for GQLPT using node.js?

Question

I am trying to setup a project for GQLPT (can't create new tag because << reputation), and in their "Get Started" docs, they have given steps which (as of now) are:

1. Obtain API key (I have obtained for Anthropic and OpenAI)
2. Download NPM package (Downloaded for both Anthropic and OpenAI)
3. setup index.js (Node should be version 18 and above. I have version 19.9.0)

According to docs, the code to paste in the index.js file is

import { AdapterOpenAI } from "@gqlpt/adapter-openai";

import { GQLPTClient } from "gqlpt";

const client = new GQLPTClient({
  typeDefs: `
    type User {
      id: ID!
      name: String!
    }

    type Query {
      user(id: ID!): User
    }
  `,
  adapter: new AdapterOpenAI({
    apiKey: process.env.OPENAI_API_KEY,
  }),
});

async function main() {
  await client.connect();
  const query = "Find users by id 1";
  const response = await client.generateQueryAndVariables(query);
  console.log(response);
}

main();

However I have integrated the api within the code block just for testing,

const apiKey = "API-GOES-HERE"; // Replace with your actual API key

const client = new GQLPTClient({
  typeDefs: `
    type User {
      id: ID!
      name: String!
    }

    type Query {
      user(id: ID!): User
    }
  `,
  adapter: new AdapterAnthropic({
    apiKey: apiKey, // Directly pass the embedded API key
  }),
});

and also called

const { AdapterAnthropic } = require("@gqlpt/adapter-anthropic");
const { GQLPTClient } = require("gqlpt");

rather than using import.

The error I receive upon running node index.js is as follows:

status: 400,
  headers: {
    'cf-cache-status': 'DYNAMIC',
    'cf-ray': 'HIDDEN-BY-ME-FOR-ONLINE-POST-HEHE',
    connection: 'keep-alive',

    via: '1.1 google',
    'x-robots-tag': 'none',
    'x-should-retry': 'false'
  },
  request_id: 'HIDDEN-BY-ME-FOR-ONLINE-POST-HEHE',
  error: {
    type: 'error',
    error: {
      type: 'invalid_request_error',
      message: 'Your credit balance is too low to access the Anthropic API. Please go to Plans & Billing to upgrade or purchase credits.'
    }
  }
}

I am using free tier for Anthropic API. OpenAI also gave same error. Is the problem an underlying one or am I simply using free tier and that is causing the error. (my first time using either API's)

I tried following the instructions here: https://www.gqlpt.dev/docs/getting-started and rather than setting environment variable, I hardcoded api in the index.js code.

Then I received error "Cannot use import statement outside a module" so I used const rather than import.

The error 401 changed to 400 and rest is shown in main post.

According to https://www.anthropic.com/pricing#claude-ai-plans, FREE tier only allows to "Talk to Claude on the web" and such. There is no FREE tier for API usage as per https://www.anthropic.com/pricing#anthropic-api, therefore you was asked for credits right from the start.
