Gemini Deep Research API Automation

This skill automates research using Google's Gemini Deep Research API - no browser automation required.

Overview

The Gemini Deep Research API provides programmatic access to Google's multi-step research agent:

1. •Autonomously plans research strategy
2. •Executes web searches across multiple sources
3. •Synthesizes findings into a comprehensive report with citations
4. •Runs asynchronously with status polling

Time: Research typically takes 3-10 minutes depending on complexity (max 60 minutes).

Output: Comprehensive research report with inline citations and source links.

Focus Areas:

• •Regulatory frameworks and telecommunications legislation
• •Government policy documents and strategic plans
• •Market structure analysis
• •Comparative policy analysis across jurisdictions
• •Stakeholder position papers

Prerequisites

• •Google AI API key in /Users/valorengels/.env (auto-loaded via ~/.zshenv)
• •Python 3.x with required dependencies installed
• •API key from: https://aistudio.google.com/apikey

API Key Setup

Check if API key exists:

grep GOOGLE_AI_API_KEY /Users/valorengels/.env

If not found, add to global .env file:

# API keys are stored in /Users/valorengels/.env (auto-loaded via ~/.zshenv)
echo 'GOOGLE_AI_API_KEY=your-api-key-here' >> /Users/valorengels/.env

Getting an API key:

1. •Go to https://aistudio.google.com/apikey
2. •Sign in with your Google account
3. •Create a new API key
4. •Copy the key and add to .env file

Complete Automation Workflow

Step 1: Verify API Key

Use Bash to check if the API key is configured:

grep GOOGLE_AI_API_KEY .env

If not found, inform user to set up API key at https://aistudio.google.com/apikey

Step 2: Prepare Research Prompt

The research prompt should be saved in the episode's prompts.md file under the Gemini Deep Research section.

Prompt format (3 lines, single newlines):

Research [TOPIC].
Focus on regulatory frameworks, legislation, government policy documents, strategic plans, and comparative policy analysis.
Provide findings with official source citations, effective dates, and policy context.

Step 3: Run Research via Python Script

Execute the Python script using Bash:

cd /Users/valorengels/src/research/podcast/tools
python gemini_deep_research.py --file ../episodes/[episode-dir]/prompts.md --output ../episodes/[episode-dir]/gemini-results.md

Or with inline prompt:

python gemini_deep_research.py "Research prompt here"

Available options:

• •--file FILEPATH - Read prompt from file
• •--output FILEPATH - Write results to file
• •--stream - Use streaming mode for real-time output
• •--poll-interval SECONDS - Seconds between status checks (default: 120)
• •--max-wait MINUTES - Maximum wait time (default: 60)
• •--quiet - Minimal output (just the result)

Step 4: Monitor Progress

The script will:

1. •Submit research request to Gemini API
2. •Display interaction ID and estimated time
3. •Poll every 2 minutes for status updates
4. •Show progress: "in_progress", "completed", or "failed"

Expected output:

==============================================================
GEMINI DEEP RESEARCH API
==============================================================

Prompt: Research Solomon Islands telecommunications...

Submitting research request...

Research started successfully!
Interaction ID: abc123xyz
Status: in_progress
Estimated time: 3-10 minutes (max 60 minutes)
Polling every 120 seconds...
--------------------------------------------------------------

[10:30:15] Status check #1 (elapsed: 120s)
Status: in_progress
Research in progress. Waiting 120s...

[10:32:15] Status check #2 (elapsed: 240s)
Status: completed

==============================================================
RESEARCH COMPLETE (took 240s)
==============================================================

Step 5: Extract and Save Results

If --output was specified, results are automatically saved to the file.

Otherwise, the script prints results to stdout and you should:

1. •Copy the research output
2. •Paste into the episode's research-results.md under the Gemini section

Recommended workflow:

# Run with output file
python gemini_deep_research.py \
  --file ../episodes/episode-dir/prompts.md \
  --output ../episodes/episode-dir/gemini-results.md

# Append to research-results.md
cat ../episodes/episode-dir/gemini-results.md >> ../episodes/episode-dir/research-results.md

if [ $? -eq 0 ]; then
  echo "Gemini research complete"
  # Append to main research results
  cat "../${EPISODE_DIR}/research-results-gemini.md" >> "../${EPISODE_DIR}/research-results.md"
else
  echo "Gemini research failed - check error messages"
fi

Why API-Based Automation

This skill uses the official Gemini Deep Research API for maximum reliability:

• •Stable: No UI changes breaking selectors
• •Simple: Just API key configuration needed
• •Scriptable: Fully automated, no browser required
• •Portable: Works in any environment with Python and internet
• •Official: Direct API access to Google's research agent
• •Maintainable: API contracts are stable and documented

Best Practices

1. •Always verify API key before running research
2. •Use background mode (default) for research
3. •Set reasonable poll intervals (2 minutes is good balance)
4. •Save output to file using --output flag
5. •Handle errors gracefully - check exit code before continuing
6. •Monitor API usage to control costs
7. •Use specific prompts - vague prompts waste API calls
8. •Test with simple prompts before complex research

Example Commands
