getRedditCommentsByKeywords
Search Reddit comments by keywords. Searches in comment body text. FAST (default, omit responseType or responseType="fast"): Returns up to 300 results directly (use limit param to reduce, e.g. limit=5). Results include guidance for full mode. PAGING (responseType="paging"): Async paginated results (100/page), returns operationId for polling via checkOperationStatus. Supports pageNumber/tableName for subsequent pages. CSV (responseType="csv"): Async single CSV download, returns operationId, poll for S3 link. CODE EXECUTION: For csv mode, download CSV and use code execution to analyze full dataset. Ideal for: sentiment analysis, discussion trends, community opinions across thousands of comments. DATABASE-ONLY: Searches existing database records only. QUERY SYNTAX: Plain keywords (bitcoin, climate change), quoted phrases ("deep learning"), boolean expressions (AI AND crypto, bitcoin OR ethereum, politics NOT sports), or parenthesized groups ((startup OR entrepreneur) NOT "venture capital"). AND/OR/NOT must have a term on both sides. @handles like @karpathy are supported. Field operators (from:, lang:) are stripped. Forward slashes are treated as spaces (24/7 becomes 24 7). Date filters: OMIT startDate/endDate parameters by default. ONLY pass these if user explicitly requests specific date range (YYYY-MM-DD format). IMPORTANT!!!!!: THE CURRENT YEAR IS 2026. When user requests relative dates (last week, last month), verify the current date from your system context and double-check the calculated dates - models often get the year wrong, searching one year earlier than intended. FILTERS: subreddit (limit to specific subreddit without r/ prefix). Optional fields parameter for performance: ["id", "body", "authorUsername", "postSubredditName", "score", "createdAtDate"]. Returns by default: id, body, authorUsername, createdAtDate. This is a safe, read-only tool for analyzing searchable information.

| query | Yes | Full-text search of comment content. Searches comment body text. EXACT PHRASES: Wrap in double quotes - "machine learning" matches that exact phrase. KEYWORDS: Without quotes, matches comments containing any of the words - AI robotics blockchain. BOOLEAN OPERATORS: MUST explicitly use the keywords AND, OR (uppercase or lowercase). NO implicit operators - space between words means OR by default. Examples requiring explicit operators: Use "deep learning" AND python (not "deep learning python"). Use tensorflow OR pytorch (not "tensorflow pytorch"). PARENTHESES: Group terms for precise logic - (AI OR "artificial intelligence") AND ethics. Query examples: "climate change" | AI OR blockchain | "neural networks" AND python | (startup OR entrepreneur) | |

| feedback | No | Optional. Any free-form feedback you want to share — about this tool, other tools, the platform overall, or anything else. Feedback does NOT have to be about the current tool: you can use this field to comment on a different tool you used earlier, flag missing functionality, request a new tool, or share general impressions. Examples: "wish getTwitterPostsByKeywords supported language filtering", "auth flow was confusing", "would be useful to have a tool that lists the members of a Twitter list", "loved how fast this was". Captured for product feedback; does not affect tool behavior. | |
