How to Compare APIs on RapidAPI by Price and Popularity

Comparing APIs on RapidAPI meant thirty tabs and a spreadsheet

Picking an API off RapidAPI Hub usually turns into thirty open tabs and a homemade spreadsheet: pricing on one tab, latency on another, ratings on a third, and no way to sort any of it. The catalog is public, but there is no export. I rebuilt that spreadsheet one too many times, so I packaged the whole marketplace into one API call instead.

What the RapidAPI Marketplace API does

The RapidAPI Marketplace API searches public API listings on RapidAPI and returns each one as a JSON row carrying its pricing model, category, popularity score, reliability metrics, and publisher, so you can compare APIs on RapidAPI by price and popularity in a single run. No RapidAPI account, login, or key is required.

What each row returns

• title, name, description, and the listing url

• pricing model: FREE, FREEMIUM, or PAID

• popularityScore from 0 to 10, plus avgLatency and avgSuccessRate

• detailed mode adds billingPlans, subscriptionsCount, ratingScore, and ratingVotes

Run it in three steps

1. Open the RapidAPI Marketplace API and click Try for free.

2. Add one or more search terms, set a max results count, and optionally turn on detailed mode.

3. Run it and export the dataset as JSON, CSV, or Excel.

Use it as a REST API

Every run is a plain REST call, so you can trigger it from any language or a cron job:

POST /v2/acts/johnvc~rapidapi-marketplace-api/runs?token=YOUR_APIFY_TOKEN
Content-Type: application/json

{
 "searchTerms": ["weather"],
 "maxResults": 25,
 "detailedInfo": true
}

Wire it into Claude with MCP

Over the Model Context Protocol, the Actor becomes a tool that Claude, Claude Code, or Cursor can call. Ask "find me a freemium geocoding API with good reliability" and you get a live catalog query with real pricing and popularity numbers behind the answer, no scraping code.

What people build with it

Common runs include comparing crypto APIs, scanning the AI niche, filtering to free plans, and ranking web scraping APIs by popularity. The full set of 40 preconfigured tasks is on the examples tab.

FAQ About Scraping RapidAPI

Where does the RapidAPI scraper get its data, and how fresh is it?

It reads the public RapidAPI marketplace listings, the same pages any visitor sees, at run time, so each run reflects the catalog as it stands that day. There is no cached snapshot; you get current pricing, popularity, and reliability numbers.

How do I call the RapidAPI API over REST, and what does it cost?

Send a POST to the Actor's run endpoint with your search terms and read the dataset back as JSON, CSV, or Excel. Pricing is a loss leader at 0.0001 dollars per listing returned, so a 500-listing category scan costs about five cents, and you only pay for rows actually delivered.

Can an AI agent use this scraper from Claude over MCP?

Yes. Connected through the Apify MCP server, the Actor appears as a callable tool in Claude, Claude Code, and Cursor, taking the same search inputs, so an agent can shortlist APIs mid-conversation with real numbers.

Can an AI agent pay for this scraper in USDC with x402?

Yes. The RapidAPI Marketplace API supports agentic payments via the x402 protocol, so AI agents and MCP clients can pay for runs in USDC on Base with no Apify account or API token. Point your agent at the Apify MCP server and it can discover, pay for, and run the scraper autonomously; the Apify x402 announcement has the details.

Issues get a same-day reply. Point the RapidAPI Marketplace API at your category and get the whole field as one sortable dataset.
