get_all_topic_posts
Retrieve all posts from a USCardForum topic with automatic pagination, allowing control over post range and limits for efficient content access.
Instructions
Fetch all posts from a topic with automatic pagination.
Args:
topic_id: The numeric topic ID
include_raw: Include markdown source (default: False)
start_post_number: First post to fetch (default: 1)
end_post_number: Last post to fetch (optional, fetches to end if not set)
max_posts: Maximum number of posts to return (optional safety limit)
This automatically handles pagination to fetch multiple batches.
IMPORTANT: For topics with many posts (>100), use max_posts to limit
the response size. You can always fetch more with start_post_number.
Use cases:
- Fetch entire small topic: get_all_topic_posts(topic_id=123)
- Fetch first 50 posts: get_all_topic_posts(topic_id=123, max_posts=50)
- Fetch posts 51-100: get_all_topic_posts(topic_id=123, start_post_number=51, max_posts=50)
- Fetch specific range: get_all_topic_posts(topic_id=123, start=10, end=30)
Returns the same Post structure as get_topic_posts but for all matching posts.
Pro tip: Use get_topic_info first to check post_count before deciding
whether to fetch all or paginate manually.
