RapidAPI Marketplace API for API Discovery

Turn the entire RapidAPI marketplace into structured data. This API searches and extracts public API listings from RapidAPI, returning pricing, categories, popularity and reliability metrics, publisher details, billing plans and ratings. No RapidAPI account, login, or key required.

It is built as a low-cost, pay-per-result loss leader, one of the cheapest ways on Apify to pull marketplace data for API discovery, market research, and competitive intelligence.

What it does

• Search the marketplace by one or many keywords and collect every matching API.
• Filter by category and sort by relevance, trending, last updated, or alphabetical.
• Pull rich detail per API: full billing plans, subscriber counts, ratings, readme docs, and website.
• Extract directly from RapidAPI API URLs or whole collection pages.

What you can extract

Field	Description
name / title	API name and display title
description / longDescription	Short and full descriptions
pricing	Pricing model (FREE, FREEMIUM, PAID)
category	Primary marketplace category
popularityScore	RapidAPI popularity score (0-10)
avgLatency	Average response latency in ms
avgServiceLevel / avgSuccessRate	Reliability metrics (%)
ratingScore / ratingVotes	User rating and vote count (detailed)
subscriptionsCount	Number of subscribers (detailed)
publisher / publisherUsername	Who publishes the API
billingPlans	Full subscription plans with prices and quotas (detailed)
websiteUrl	Publisher website (detailed)
readme	API documentation readme (detailed)
url	Public RapidAPI page link

What you get: example output

Every result is a flat JSON record, one per API listing, ready for a spreadsheet, a database, or an AI agent. Basic search results carry the core fields; set detailedInfo to add billing plans, ratings, subscriber counts, and the full readme. Here is a trimmed example of what the API returns for one detailed listing:

{
  "name": "open-weather-map",
  "title": "Open Weather Map",
  "description": "Current weather, forecasts, and historical data for any location.",
  "longDescription": "Access current conditions, hourly and daily forecasts, and historical weather by city name, ZIP code, or coordinates.",
  "pricing": "FREEMIUM",
  "category": "Weather",
  "popularityScore": 9.8,
  "avgLatency": 142,
  "avgServiceLevel": 100,
  "avgSuccessRate": 99,
  "ratingScore": 4.6,
  "ratingVotes": 512,
  "subscriptionsCount": 84213,
  "publisher": "WeatherData Inc",
  "publisherUsername": "weatherdata",
  "billingPlans": [
    {"name": "Basic", "price": 0, "quota": "60 requests/minute"},
    {"name": "Pro", "price": 10, "quota": "600 requests/minute"}
  ],
  "websiteUrl": "https://example-weather.com",
  "url": "https://rapidapi.com/weatherdata/api/open-weather-map"
}

Use cases

• API discovery: find every API matching a keyword or category.
• Market research: analyze pricing models and popularity across thousands of APIs.
• Competitive intelligence: track which APIs lead your niche and how they price.
• Lead generation: build a database of API publishers and their websites.
• Trend analysis: monitor trending and recently updated APIs over time.

🔌 Integrations: Automate API Discovery and Market Research

A single run answers one question ("which weather APIs are trending today?"). The real value comes from running this API on a schedule, so a fresh snapshot of the marketplace lands in your stack every day and you can watch pricing, popularity, and new entrants change over time. See the full list of Apify platform integrations.

Tasks and Schedules (the core recipe). Save one task per thing you track (a category like "Finance", a keyword like "weather", or a competitor's publisher page), then attach a schedule from the Actor's Actions, then Schedule menu. Each run appends a fresh snapshot to the same dataset. Useful cron strings: 0 7 * * * (daily at 7 AM), 0 */6 * * * (every six hours), 0 9 * * 1 (Mondays). One schedule can trigger many tasks at once.

n8n. Run this API inside an n8n workflow: a Schedule Trigger, then the Apify node running johnvc/rapidapi-marketplace-api, then a Filter on popularityScore or pricing, then a Slack or email node to alert you when a new API enters your niche. This API also ships a dedicated n8n community node, n8n-nodes-rapidapi-marketplace-api: in n8n open Settings, Community Nodes, and install it, then use it in any workflow or as an AI Agent tool.

Make and Zapier. The same pattern works no-code with Make and Zapier: trigger on a schedule, run the Actor, route the new rows wherever you need them.

Store the history (Supabase). Send each run's rows into a table so a price and popularity history accumulates over time. No-code: the n8n Apify node, then a Supabase node. Or in Python, using the real output fields (name, category, pricing, popularityScore, avgSuccessRate, publisher, url):

from apify_client import ApifyClient
from supabase import create_client

apify = ApifyClient("YOUR_APIFY_TOKEN")
supabase = create_client("YOUR_SUPABASE_URL", "YOUR_SUPABASE_KEY")

run = apify.actor("johnvc/rapidapi-marketplace-api").call(run_input={
    "searchTerms": ["weather", "finance"],
    "maxResults": 100,
    "detailedInfo": True,
})
rows = list(apify.dataset(run.default_dataset_id).iterate_items())
supabase.table("rapidapi_listings").upsert(rows).execute()

MCP and AI agents. Add this API as a tool in Claude Code (free trial), Claude Cowork (free trial), or Cursor through the Apify MCP server, so an agent can answer questions like "what are the five most popular free finance APIs on RapidAPI right now?" with live data (see the Use this API from Claude section below).

Webhooks. For anything custom, fire an Apify webhook on ACTOR.RUN.SUCCEEDED to push each run's dataset into your own service.

Input

Field	Type	Description
searchTerms	array	Keywords to search, one per line. Empty plus empty Listing URLs returns all APIs.
category	string	Optional single category filter (for example Data, Finance, Weather).
sortBy	select	Relevance, Trending, Last updated, or Alphabetical.
order	select	Ascending or Descending.
maxResults	integer	Max results per search term (up to 1000).
detailedInfo	boolean	Enrich each result with full detail by fetching its API page.
listingUrls	array	RapidAPI API or collection URLs to extract directly (always detailed).

Example input

{
  "searchTerms": ["linkedin", "weather"],
  "category": "Data",
  "sortBy": "ByTrending",
  "order": "DESC",
  "maxResults": 50,
  "detailedInfo": false
}

Pricing

This Actor uses pay-per-result pricing and is deliberately priced as a loss leader, among the cheapest options on Apify for marketplace data:

• Basic listing result: 0.0001 USD each.
• Detailed API result: 0.0001 USD each (includes an extra page fetch per API for billing plans, ratings, readme, and subscriber counts, at the same low rate).

You only pay for results actually returned. Set a run budget and the Actor stops cleanly when the budget is reached.

How to get started

1. Add your search terms or listing URLs.
2. Click Start. Results stream to the dataset as they are found.
3. Export as JSON, CSV, or Excel, or pull them through the Apify API.

🔗 Related Tools

Building an API and marketplace intelligence pipeline? These tools from the same catalog pair well with RapidAPI marketplace data:

• Apify Store API: the same idea for a different catalog, search and extract every Actor on the Apify Store with pricing, ratings, and usage stats.
• Apple App Store Search: discover apps by keyword across the App Store when your research spans app marketplaces, not just APIs.
• Apple App Store Product API: pull full app detail, pricing, and reviews for any listing you find.
• G2 Reviews API: read B2B software reviews to evaluate the tools and vendors you discover.

Other RapidAPI marketplace scrapers exist, such as crawlerbros/rapidapi-hub-scraper, but that one charges a per-run start fee plus roughly forty times more per result and shows minimal adoption (a handful of users). This API is a pay-per-result loss leader at 0.0001 USD per record with no start fee, actively maintained, and returns clean structured fields.

FAQ

Can I schedule this RapidAPI API to run automatically?

Yes. Any run can be automated on a schedule. Save a task with your search terms or listing URLs, then open the Actor's Actions, then Schedule menu and pick a cadence. Handy cron strings: 0 7 * * * for daily at 7 AM, 0 */6 * * * for every six hours, and 0 9 * * 1 for Monday mornings. One schedule can trigger many tasks at once, so you can track a dozen categories in parallel. See the Integrations section above for the full monitoring and storage recipe.

Should I use an API or a web scraper for API discovery?

Both, and this Actor is both. RapidAPI has no official public catalog API, so your options are a manual browse, a fragile custom web scraper, or this Actor, which gives you the clean, structured result of a purpose-built API: call it yourself or run it no-code, pay per record, and get the same JSON whether you pull one listing or the whole marketplace. No RapidAPI account or key is required.

How many results can this return?

The marketplace caps a single search at 1000 results, so the Actor stops there per search term. To gather more, pass several search terms or several listing URLs in one run; each is collected up to its own cap.

How much does it cost to collect RapidAPI data?

It is a deliberate loss leader: 0.0001 USD per basic listing and 0.0001 USD per detailed API, with no start fee and no subscription. You only pay for results actually returned, and you can set a run budget so the Actor stops cleanly when the cap is reached.

How can I use this for market research?

Point it at a category or a keyword, turn on detailedInfo, and you get pricing models, billing plans, popularity scores, latency, success rates, and subscriber counts across every matching API. Run it on a schedule to watch how a niche prices and grows over time. This is the market research and competitive intelligence use case: one structured dataset instead of hours of manual browsing.

Can I use the RapidAPI Marketplace API with the Apify API?

Yes. The Apify API runs the Actor, schedules it, and fetches datasets, and the apify-client package exists for both Node.js and Python. See the Actor's API tab for ready-made snippets.

Can I use this RapidAPI scraper through an MCP server?

Yes. Add it as a tool in any MCP client (Claude, Cursor, and others) through the hosted Apify MCP server with the Actor-specific URL https://mcp.apify.com/?tools=actors,docs,johnvc/rapidapi-marketplace-api. In Claude Code (free trial) or Claude Cowork (free trial) your agent can then answer questions like "which OCR APIs on RapidAPI have the best success rate?" with live data. See the Apify MCP docs.

Can I integrate this API with other apps?

Yes. It connects to almost any cloud service through Apify integrations: Make, Zapier, Slack, n8n, and webhooks on ACTOR.RUN.SUCCEEDED for custom actions. See the Integrations section above for full recipes.

Is it legal to scrape RapidAPI listings?

This Actor reads only public marketplace pages on RapidAPI and does not require or use a RapidAPI account. As with any scraping, use the data responsibly and respect the source's terms. For background, see Apify's overview of the legality of web scraping.

How can I discover and track other marketplaces and catalogs?

Pair this API with related tools in the same catalog: the Apify Store API for the Apify Actor catalog, Apple App Store Search and the Apple App Store Product API for the app marketplace, and the G2 Reviews API to evaluate the software you find.

Notes

• This Actor reads only public marketplace pages. It does not require or use a RapidAPI account.
• The marketplace caps a single search at 1000 results. Use multiple search terms to gather more.
• Be a good citizen: scrape responsibly and respect RapidAPI's terms.
