• "Get me the latest posts from r/bittensor about dTAO"

• "Fetch 50 tweets about #AI from the last week"

2. create_gravity_task - Large-Scale Data Collection

Create a Gravity task for collecting large datasets over 7 days. Use this when you need more than 1000 results.

Parameters:

Task object structure:

{
  "platform": "x",           // 'x' or 'reddit'
  "topic": "#Bittensor",     // For X: MUST start with '#' or '$'
  "keyword": "dTAO"          // Optional: filter within topic
}

Important: For X (Twitter), topics MUST start with # or $ (e.g., #ai, $BTC). Plain keywords are rejected.

Example prompts:

• "Create a gravity task to collect #Bittensor tweets for the next 7 days"

• "Start collecting data from r/MachineLearning about neural networks"

3. get_gravity_task_status - Check Collection Progress

Monitor your Gravity task and see how much data has been collected.

Parameters:

Returns: Task status, crawler IDs, records_collected, bytes_collected

Example prompts:

• "Check the status of my Bittensor data collection task"

• "How many records have been collected so far?"

4. build_dataset - Build & Download Dataset

Build a dataset from collected data before the 7-day completion.

Warning: This will STOP the crawler and de-register it from the network.

Parameters:

Example prompts:

• "Build a dataset from my Bittensor crawler with 5000 rows"

• "I have enough data, build the dataset now"

5. get_dataset_status - Check Build Progress & Download

Check dataset build progress and get download links when ready.

Parameters:

Returns: Build status (10 steps), and when complete: download URLs for Parquet files

Example prompts:

→ Returns up to 1000 results instantly

Large Dataset Collection (Gravity)

User: "I need to collect a week's worth of #AI tweets for analysis"

1. create_gravity_task → Returns gravity_task_id
2. get_gravity_task_status → Monitor progress, get crawler_ids
3. build_dataset → When ready, build the dataset
4. get_dataset_status → Get download URL for Parquet file

Example Prompts

On-Demand Queries

• "What has the president of the U.S. been saying over the past week on X?"

• "Fetch me information about what people are posting on r/politics today."

• "Please analyze posts from @elonmusk for the last week."

• "Get me 100 tweets about #Bittensor and analyze the sentiment"

• "Start a 7-day collection of $BTC tweets with keyword 'ETF'"

• "Check how many records my gravity task has collected"

• "Build a dataset with 10,000 rows from my crawler"
