How to scrape Facebook Marketplace Search with Swift

Marketplace Search This tutorial gets it with a short Swift program and the Facebook Marketplace Search API. Each successful call costs 1 credit; errors and not-found answers are free.

1. Get an API key

Sign in to get a key and 100 free credits, no card. Then put the key in an environment variable so it stays out of your code:

export SCRAPEIO_API_KEY="your_key_here"

2. Set up Swift

Swift 5.7 or newer (macOS or Linux)

3. Write the code

Save this as main.swift. Replace YOUR_LAT with a real lat, YOUR_LNG with a real lng.

import Foundation
#if canImport(FoundationNetworking)
import FoundationNetworking
#endif

var components = URLComponents(string: "https://scrapeio.com/v1/facebook/marketplace/search")!
components.queryItems = [URLQueryItem(name: "lat", value: "YOUR_LAT"), URLQueryItem(name: "lng", value: "YOUR_LNG")]
var request = URLRequest(url: components.url!)
request.setValue(ProcessInfo.processInfo.environment["SCRAPEIO_API_KEY"], forHTTPHeaderField: "x-api-key")

let done = DispatchSemaphore(value: 0)
URLSession.shared.dataTask(with: request) { data, response, error in
    defer { done.signal() }
    guard let data = data, (response as? HTTPURLResponse)?.statusCode == 200 else {
        print("Request failed:", error?.localizedDescription ?? "HTTP \((response as? HTTPURLResponse)?.statusCode ?? 0)")
        return
    }
    print(String(data: data, encoding: .utf8) ?? "")
}.resume()
done.wait()

This prints the first page. To get the next one, send the value of data.cursor as the cursor parameter and call again until data.has_more is false.

4. Run it

swift main.swift

The response has the same envelope on every endpoint: success, cached, credits_used, credits_remaining and data. Shared fields such as handle, followers, plays, likes and created_at have the same names on every platform.

Prefer no code?

Connect the MCP server to Claude Code, Cursor or Codex and ask in plain English. The agent uses call_endpoint with path /v1/facebook/marketplace/search for you.
