RS Online Scraper API

The Piloterr RS Online Scraper API lets you extract public data from RS Online as clean, structured JSON — no proxies, headless browsers or HTML parsing to maintain. Endpoints available in production:

RS Online Product API — Read one RS Online UK product URL, including the RS stock number, manufacturer part, and pound price.
RS Online Search API — Search RS Online UK by keyword or category.

Use it for price monitoring, assortment tracking, competitor analysis, product research or catalog enrichment.

Endpoint	Path	Credits	What you get
RS Online Product API	`/v2/rsonline/product`	2	Read one RS Online UK product URL, including the RS stock number, manufacturer part, and pound price.
RS Online Search API	`/v2/rsonline/search`	2	Search RS Online UK by keyword or category. Pound prices keep the amount printed on the page.

How it works

Create a free Piloterr account and copy your API key from the dashboard.
Send a GET (or POST) request to https://api.piloterr.com/v2/... with the header x-api-key: YOUR_API_KEY.
Receive structured JSON — Piloterr handles rendering, proxies, retries and parsing.

export PILOTERR_API_KEY="your-api-key"
pip install requests        # Python
# TypeScript: Node.js 18+ (native fetch), run with `npx tsx file.ts`

Every endpoint accepts both GET (query string) and POST (JSON body with the same fields).

Python example

import json

import requests

response = requests.get(
    "https://api.piloterr.com/v2/rsonline/product",
    headers={"x-api-key": os.environ["PILOTERR_API_KEY"]},

    },
    timeout=120,
)
response.raise_for_status()
data = response.json()

print(json.dumps(data, indent=2, ensure_ascii=False)[:2000])

RS Online Search API

Search RS Online UK by keyword or category. Pound prices keep the amount printed on the page.

GET | POST https://api.piloterr.com/v2/rsonline/search · 2 credits per request · Full reference

Request parameters

Parameter	Type	Required	Description
`query`	string	✅	A keyword, or a uk.rs-online.com search or category link. Empty, another host, or a product link returns 400. A keyword builds /web/c/?searchTerm=... and page 1 omits pn. Each card has price as a number and price_display…
`page`	number	—	Page number starting at 1. Omit it for page 1. Page 2 sets pn=2, changes pagination.page, and returns the next cards. pagination.next is that next URL, or null on the last page. A value below 1 returns 400.
`return_page_source`	boolean	—	Default false. true replaces results and pagination with result, the rendered HTML.

FAQ

Is it legal to scrape RS Online?

Collecting publicly available data is generally allowed in many jurisdictions, but rules depend on your country, the data you collect and how you use it. Avoid personal data unless you have a lawful basis, respect the website's terms where they apply, and get legal advice for your specific use case. This is not legal advice.

Do I need proxies or a headless browser?

No. Piloterr handles rendering, proxy rotation and retries on its side. You only send an HTTPS request with your x-api-key header and receive JSON.

How much does a request cost?

Credits per call: /v2/rsonline/product 2, /v2/rsonline/search 2. See the Piloterr website for plans.

What data does the RS Online API return?

Each endpoint returns structured JSON: RS Online Product — mpn, url, brand, price, title, images; RS Online Search — results[], results[].mpn, results[].url, results[].brand, results[].price, results[].title.

How do I paginate RS Online results?

Use the page parameter and keep requesting while the response indicates more results.

Can I get the raw HTML instead of JSON?

Yes. Set return_page_source=true and the response becomes {"result": "..."} with the page source.

Which languages are supported?

Any language that can make an HTTP request. This README shows Python and TypeScript; the examples/ folder contains cURL, PHP, C#, Go, Java, Ruby and Node.js.
