Dropshipping Product Research API Guide

Automate product research: Amazon bestsellers, Walmart deals, Google Shopping trends. Single API covers all three platforms. Daily trend tracking pipeline.

May 19, 2026

Manual product research for dropshipping means hours of scrolling Amazon bestseller lists, checking Walmart deals, and searching Google Shopping trends. Automating this with a single API that covers all three platforms produces a daily trend report for under $1/day. The pipeline: search bestsellers on Amazon, cross-check prices on Walmart, and verify demand on Google.

Pipeline architecture

  1. Search Amazon for trending products in target categories
  2. Search Walmart for the same products to compare pricing
  3. Search Google for demand signals (search volume proxy via SERP features)
  4. Score products by price gap, demand signals, and competition level
  5. Export top opportunities to a spreadsheet daily

Step 1: find trending products

Python
import requests, os

H = {"x-api-key": os.environ["SCAVIO_API_KEY"]}

def search_platform(query: str, platform: str):
    """Search a platform and return structured results."""
    resp = requests.post("https://api.scavio.dev/api/v1/search",
        headers=H, json={"query": query, "platform": platform})
    return resp.json().get("organic_results", [])

def find_trending_products(categories: list):
    """Search Amazon for trending products in each category."""
    products = []
    for cat in categories:
        results = search_platform(f"best selling {cat} 2026", "amazon")
        for r in results[:5]:
            products.append({
                "category": cat,
                "title": r.get("title", ""),
                "price": r.get("price"),
                "rating": r.get("rating"),
                "url": r.get("link", ""),
                "platform": "amazon",
            })
    return products

categories = ["kitchen gadgets", "phone accessories", "home organization"]
trending = find_trending_products(categories)
# 3 categories = 3 API calls = $0.015

Step 2: cross-platform price comparison

Python
def cross_check_prices(products: list):
    """Check Walmart and Google for price comparisons."""
    enriched = []
    for p in products[:10]:  # Top 10 products
        short_title = " ".join(p["title"].split()[:5])

        # Check Walmart price
        walmart = search_platform(short_title, "walmart")
        walmart_price = walmart[0].get("price") if walmart else None

        # Check Google Shopping for demand
        google = search_platform(f"{short_title} buy", "google")
        has_ads = bool(any("ad" in str(r).lower() for r in google[:3]))

        enriched.append({
            **p,
            "walmart_price": walmart_price,
            "has_google_ads": has_ads,
            "demand_signal": "high" if has_ads else "moderate",
        })
    return enriched

# 10 products x 2 platforms = 20 API calls = $0.10
enriched = cross_check_prices(trending)

Step 3: daily trend tracker

Python
import csv
from datetime import date

def daily_product_report(categories: list, output_file: str = None):
    """Generate daily product opportunity report."""
    trending = find_trending_products(categories)
    enriched = cross_check_prices(trending)

    # Score opportunities
    for p in enriched:
        score = 0
        if p.get("has_google_ads"):
            score += 2  # demand signal
        if p.get("rating") and float(str(p["rating"]).replace(",", ".")) >= 4.0:
            score += 1  # quality signal
        p["opportunity_score"] = score

    # Sort by score
    enriched.sort(key=lambda x: x["opportunity_score"], reverse=True)

    # Export to CSV
    if output_file and enriched:
        with open(output_file, "w", newline="") as f:
            writer = csv.DictWriter(f, fieldnames=enriched[0].keys())
            writer.writeheader()
            writer.writerows(enriched)

    return enriched

# Total daily cost: ~25 API calls = $0.125/day = $3.75/mo
report = daily_product_report(
    ["kitchen gadgets", "phone accessories", "home organization"],
    f"products_{date.today().isoformat()}.csv"
)

Cost breakdown

  • 5 categories, daily tracking: ~35 API calls/day = $0.175/day = $5.25/mo
  • 10 categories: ~60 calls/day = $0.30/day = $9/mo
  • All within Scavio's $30/mo Project plan (7K credits)
  • Compare: Jungle Scout at $49/mo, Helium 10 at $39/mo (Amazon-only)
