  title: APIs.io Paginate Search Results
  summary: Read the first page of a keyword search, learn the total page count, then fetch a following page of results.
  description: >-
    The APIs.io search response carries pagination metadata — the total number
    of pages plus self, next, and last links. This workflow walks that
    pagination: it reads the first page to discover how many pages of results
    exist for a keyword, branches on whether more than one page is available,
    and when it is, fetches the next page so a caller can accumulate results
    across pages. Each step inlines its request, including the required API key
    header, so the flow is self-describing.
