This assumes you have already created an API token and have a base 64 encoded string of the API token. Check out my article FreeKB - Atlassian - Create API token.

Using the base64 encoded string, you should now be able to submit a GET request and get JSON response. For example, to GET Confluence Pages.

More GET request examples here => The Confluence Cloud REST API

curl \
--silent \
--request GET \
--header "Accept: application/json" \
--header "Authorization: Basic <base64 encoded string>" \
--url "https://acme.atlassian.net/wiki/api/v2/pages"| jq

Something like this should be returned.

{

    {
      "parentId": null,
      "spaceId": "15335479",
      "ownerId": "557058:a9d57db5-f0d2-4c9b-b526-18382bec4da0",

    "base": "https://acme.atlassian.net/wiki"
  }
}

By default, the first 25 pages will be returned. Notice in the above output there is a "next" endpoint. The "next" endpoint can be used to return the next 25 pages.

curl \
--silent \
--request GET \
--header "Accept: application/json" \
--header "Authorization: Basic <base64 encoded string>" \
--url "https://acme.atlassian.net/wiki/api/v2/pages?cursor=eyJpZCI6IjE1MzM1NTg1IiwiY29udGVudE9yZGVyIjoiaWQiLCJjb250ZW50T3JkZXJWYWx1ZSI6MTUzMzU1ODV9"| jq

The limit parameter can be used to return a specific number of spaces. The value must be between 1 - 250.

curl \
--silent \
--request GET \
--header "Accept: application/json" \
--header "Authorization: Basic <base64 encoded string>" \
--url "https://acme.atlassian.net/wiki/api/v2/pages?limit=1"| jq

If you want to return pages in a space, you can submit a GET request to the spaces endpoint to get the space ID.

curl \
--request GET \
--header "Accept: application/json" \
--header "Authorization: Basic <base64 encoded string>" \
--url "https://acme.atlassian.net/wiki/api/v2/spaces"| jq

For example, let's say the space ID is 12345678. You can then submit a GET request to the pages endpoint including the space-id URL paramater to only return the pages in the space.

curl \
--silent \
--request GET \
--header "Accept: application/json" \
--header "Authorization: Basic <base64 encoded string>" \
--url "https://acme.atlassian.net/wiki/api/v2/pages?space-id=12345678"| jq
