API Marketplace Trend Radar

Find API product opportunities before they become obvious. This Actor scans public API marketplaces, ranks hot products, saves daily snapshots, and turns marketplace signals into practical API product ideas.

Fast trial paths

• Run a baseline scan with Apify only to get the strongest public usage signals quickly.
• Run a weekly multi-market scan across Apify, ApyHub, APILayer, and RapidAPI to spot API niches with repeated demand.
• Use the opportunity-ideas.json output as a build queue for new APIs, scrapers, templates, SEO pages, and agency offers.

For repeat use, schedule the Actor daily and review top-growth-apis.json every week. Growth comparisons become more useful after at least two saved snapshots.

What this Actor does

• Scans API marketplaces such as Apify Store, ApyHub, APILayer, and public RapidAPI pages when available
• Ranks APIs by current demand signals such as 7-day users, 30-day users, runs, reviews, bookmarks, ratings, and marketplace rank
• Saves daily snapshots to the key-value store so later runs can calculate real 7-day growth
• Produces opportunity scores for API makers, automation agencies, SaaS builders, and data product sellers
• Generates product recommendations you can use to decide what API, scraper, automation, or data tool to build next

Why use it?

API marketplaces move fast. Popular categories like AI, scraping, lead generation, SEO, image tools, email tools, and social data often reveal demand before traditional keyword tools catch up. This Actor gives you a repeatable market-research workflow instead of manual browsing.

Sources

The scanner uses public marketplace data and treats failures as non-fatal:

• Apify Store - strongest public demand signals, including 7-day users, 30-day users, 30-day runs, reviews, ratings, and bookmarks
• ApyHub - structured catalog data with names, categories, providers, ratings, and pricing signals
• APILayer - popular marketplace cards parsed from public HTML
• RapidAPI - best-effort scan from public pages; results depend on page availability and protections

Input

{
  "sources": ["apify", "apyhub", "apilayer", "rapidapi"],
  "maxItemsPerSource": 100,
  "keywords": ["ai", "email", "scraper", "lead", "seo", "image", "pdf", "social"],
  "saveSnapshot": true,
  "compareDays": 7,
  "includeRapidApiBestEffort": true,
  "proxyConfiguration": {
    "useApifyProxy": false
  }
}

Output

Each dataset item includes:

• source
• name
• provider
• category
• url
• description
• rating
• review_count
• users_7d
• users_30d
• runs_30d
• bookmark_count
• pricing_model
• current_rank
• previous_rank
• rank_delta_7d
• metric_delta_7d
• hot_score
• growth_score
• opportunity_score
• confidence
• recommendation

The key-value store also contains:

• SUMMARY - scan summary and top opportunities
• top-hot-apis.json - strongest current demand
• top-growth-apis.json - fastest growth or strongest 7-day signals
• opportunity-ideas.json - grouped product ideas
• source-health.json - source success/failure status
• proxy_enabled in SUMMARY - whether marketplace requests used the configured proxy
• snapshot-YYYY-MM-DD.json and LATEST_SNAPSHOT - growth baselines

Proxy option

Marketplace pages can throttle or change responses. The proxyConfiguration input lets you run marketplace requests through Apify Proxy or custom proxies when direct requests return blocks, empty pages, or inconsistent marketplace pages. Leave proxy disabled for low-cost baseline scans and enable it for scheduled production monitoring.

Growth tracking note

The first run creates a baseline. Real 7-day growth requires at least two snapshots, ideally from a daily schedule. Until a comparison snapshot exists, the Actor uses current 7-day demand and marketplace rank as a baseline growth signal.

Recommended workflow

1. Run once to collect the baseline.
2. Schedule the Actor daily.
3. After 7 days, sort by growth_score and opportunity_score.
4. Pick a high-score niche and launch a focused API product with better docs, batch mode, webhooks, and clear pricing.
5. Monitor the same niche weekly to improve positioning.

Good use cases

• Find the next API product to launch on Apify, RapidAPI, or your own site
• Track competitors across API marketplaces
• Build weekly market intelligence reports
• Discover fast-growing automation and data extraction niches
• Prioritize SEO pages and product landing pages for API tools

Pricing transparency

This Actor is designed for pay-per-result pricing. A result corresponds to one marketplace item written to the dataset. Small scans are inexpensive; larger multi-source scans cost more because they produce more rows.

Suggested public pricing:

• Actor start: $0.001
• Dataset result: $0.002 per scanned API listing

Example costs:

• 100 API listings: about $0.20
• 300 API listings: about $0.60
• 1,000 API listings: about $2.00

Compliance note

This Actor does not resell third-party API access. It analyzes public marketplace information and produces market intelligence, trend rankings, and product opportunity recommendations.
