Data Scraper Agent

Build a production-ready, AI-powered data collection agent for any public data source. Runs on a schedule, enriches results with a free LLM, stores to a database, and improves over time.

Stack: Python · Gemini Flash (free) · GitHub Actions (free) · Notion / Sheets / Supabase

When to Activate

• User wants to scrape or monitor any public website or API
• User says "build a bot that checks...", "monitor X for me", "collect data from..."
• User wants to track jobs, prices, news, repos, sports scores, events, listings
• User asks how to automate data collection without paying for hosting
• User wants an agent that gets smarter over time based on their decisions

Core Concepts

The Three Layers

Every data scraper agent has three layers:

COLLECT → ENRICH → STORE
  │           │        │
Scraper    AI (LLM)  Database
runs on    scores/   Notion /
schedule   summarises Sheets /
           & classifies Supabase

Free Stack

| Layer | Tool | Why | |---|---|---| | Scraping | requests + BeautifulSoup | No cost, covers 80% of public sites | | JS-rendered sites | playwright (free) | When HTML scraping fails | | AI enrichment | Gemini Flash via REST API | 500 req/day, 1M tokens/day — free | | Storage | Notion API | Free tier, great UI for review | | Schedule | GitHub Actions cron | Free for public repos | | Learning | JSON feedback file in repo | Zero infra, persists in git |

AI Model Fallback Chain

Build agents to auto-fallback across Gemini models on quota exhaustion:

gemini-2.0-flash-lite (30 RPM) →
gemini-2.0-flash (15 RPM) →
gemini-2.5-flash (10 RPM) →
gemini-flash-lite-latest (fallback)

Batch API Calls for Efficiency

Never call the LLM once per item. Always batch:

# BAD: 33 API calls for 33 items
for item in items:
    result = call_ai(item)  # 33 calls → hits rate limit

# GOOD: 7 API calls for 33 items (batch size 5)
for batch in chunks(items, size=5):
    results = call_ai(batch)  # 7 calls → stays within free tier

Workflow

Step 1: Understand the Goal

Ask the user:

1. What to collect: "What data source? URL / API / RSS / public endpoint?"
2. What to extract: "What fields matter? Title, price, URL, date, score?"
3. How to store: "Where should results go? Notion, Google Sheets, Supabase, or local file?"
4. How to enrich: "Do you want AI to score, summarise, classify, or match each item?"
5. Frequency: "How often should it run? Every hour, daily, weekly?"

Common examples to prompt:

• Job boards → score relevance to resume
• Product prices → alert on drops
• GitHub repos → summarise new releases
• News feeds → classify by topic + sentiment
• Sports results → extract stats to tracker
• Events calendar → filter by interest

Step 2: Design the Agent Architecture

Generate this directory structure for the user:

my-agent/
├── config.yaml              # User customises this (keywords, filters, preferences)
├── profile/
│   └── context.md           # User context the AI uses (resume, interests, criteria)
├── scraper/
│   ├── __init__.py
│   ├── main.py              # Orchestrator: scrape → enrich → store
│   ├── filters.py           # Rule-based pre-filter (fast, before AI)
│   └── sources/
│       ├── __init__.py
│       └── source_name.py   # One file per data source
├── ai/
│   ├── __init__.py
│   ├── client.py            # Gemini REST client with model fallback
│   ├── pipeline.py          # Batch AI analysis
│   ├── jd_fetcher.py        # Fetch full content from URLs (optional)
│   └── memory.py            # Learn from user feedback
├── storage/
│   ├── __init__.py
│   └── notion_sync.py       # Or sheets_sync.py / supabase_sync.py
├── data/
│   └── feedback.json        # User decision history (auto-updated)
├── .env.example
├── setup.py                 # One-time DB/schema creation
├── enrich_existing.py       # Backfill AI scores on old rows
├── requirements.txt
└── .github/
    └── workflows/
        └── scraper.yml      # GitHub Actions schedule

Step 3: Build the Scraper Source

Template for any data source:

# scraper/sources/my_source.py
"""
[Source Name] — scrapes [what] from [where].
Method: [REST API / HTML scraping / RSS feed]
"""
import requests
from bs4 import BeautifulSoup
from datetime import datetime, timezone
from scraper.filters import is_relevant

HEADERS = {
    "User-Agent": "Mozilla/5.0 (compatible; research-bot/1.0)",
}


def fetch() -> list[dict]:
    """
