Web data extraction services

Custom data feeds from
any website — typically in 48 hours.

We turn websites into clean, structured data — CSV, JSON, or API. Including the hard ones: bot-protected portals, JavaScript-heavy single-page apps, and sites with no public API at all. Fixed-price projects, honest turnaround, no scraping headaches on your side.

Bot-protected sites

F5 BIG-IP TSPD, Cloudflare, session-locked flows — sites that block off-the-shelf scrapers.

JS-heavy & SPAs

React, Angular, Vue and even WebSocket-pushed apps with no conventional API to call.

Proven at scale

30+ live extractors shipped across every major site architecture. Verifiable results.

48-hour turnaround

Most jobs delivered in two days. You approve the plan and price before we start.

Case studies

Four hard sites, four clean datasets

These extractors were built for our own procurement-intelligence platform, not client engagements — but they run against real, live, adversarial public websites, and the numbers below come from our own production runs. They're a faithful preview of the work we do for clients.

Etimad / Monafasat

Saudi Arabia

Enterprise bot protection
Challenge
The national procurement portal sits behind F5 BIG-IP TSPD. Hitting the data endpoint cold returns obfuscated anti-bot JavaScript, not data — and a silent page-size cap truncates naive scrapers to ~24 of 9,500+ records.
Approach
Defeated the protection with a precise cookie handshake instead of a heavy headless browser: one warm-up request seeds the session, then authenticated pagination pulls clean JSON, with automatic session re-warm-up on expiry.

~9,500 live records per cycle · zero browser overhead · full pagination

CERN Forthcoming Procedures

Switzerland

No API, no HTML
Challenge
The data is never in the page source and never travels over a normal HTTP request — it’s an R Shiny app that pushes its table over a WebSocket, and the real descriptions only open on a genuine mouse click.
Approach
Rendered the app, waited for the WebSocket push, and parsed the materialized DOM — then drove a real browser click-through per row to recover full descriptions and named engineering contacts.

64/64 records complete on every tracked field

CEJN Montenegro

Montenegro

Angular SPA + hidden API
Challenge
An Angular single-page app shows an empty shell to any normal scraper, and the richest fields — budgets, CPV codes, contacts — only exist on a separate per-record detail view.
Approach
Reverse-engineered the undocumented .NET API the app calls, decoded its query model, and joined the listing and detail endpoints into one clean table — with concurrency limits and a circuit breaker for resilience.

~45,000 records reachable · budgets, contacts & CPV codes joined in

eTenders South Africa

South Africa

DataTables AJAX
Challenge
The opportunities grid is a jQuery DataTables endpoint speaking a verbose wire protocol that trips up static-HTML scrapers — get the parameters wrong and you get an error or the wrong slice.
Approach
Spoke the DataTables protocol directly as plain HTTP, paginated to completion using the endpoint’s own record counts, and composed rich records with contact details and document references.

Larger or unusual jobs (very high volume, many sites, complex enrichment, PDF/document parsing) are quoted individually. Ask and we'll scope it for free.

How it works

From URL to clean dataset, typically in 48 hours

01

Brief

Send the site URL and the fields you need. We reply with a fixed price, the exact delivery spec (columns, format, cadence), and a turnaround — usually within hours.

02

Build

We reverse-engineer the site's data source — hidden API, rendered DOM, or protected feed — and build a robust extractor. No brittle screen-scraping where a real API exists.

03

Deliver

You get your data as CSV, JSON, Excel, a Google Sheet, or a live API — within 48 hours for most jobs. Every field validated; missing data is flagged, never fabricated.

04

Maintain

For recurring feeds we monitor the extractor and alert on breakage — so when the site changes, we fix it before your data goes stale.

FAQ

Common questions

How fast can you deliver?
Most standard and single-page-application sites are typically delivered within 48 hours of scoping. Bot-protected sites and large recurring feeds may take a little longer; we tell you the exact turnaround before you commit, and there is no charge until you approve the plan.
Can you scrape sites that block scrapers?
Yes — this is our specialism. We routinely extract from sites behind enterprise bot protection (F5 BIG-IP TSPD, Cloudflare), JavaScript single-page apps (React, Angular, Vue), and even WebSocket-pushed apps with no conventional API. See the case studies on this page for real, verifiable examples.
Is web scraping legal?
We extract publicly-accessible data and respect each site’s terms and applicable law. We decline jobs that require bypassing authentication, harvesting personal data unlawfully, or violating a site’s terms. If a project raises a compliance question, we flag it before starting.
What format do I get the data in?
Whatever fits your workflow: CSV, JSON, Excel, a Google Sheet, or a REST API / webhook for recurring feeds. We agree the exact columns, format and refresh cadence up front in a short delivery spec so you get precisely the dataset you need.
My in-house scraper keeps breaking. Can you fix it?
Yes. Sites change their markup, add bot protection, or move to an SPA, and brittle scrapers break. We offer a rescue service: we diagnose why it broke, rebuild the extraction on a more robust foundation, and can take over ongoing maintenance so it stays fixed.
Do you offer ongoing monitored feeds?
Yes — our recurring-feed tier delivers scheduled extractions (hourly, daily, weekly) with monitoring and alerting, so you get fresh data on a cadence without babysitting it. Pricing starts at £1,500/month depending on site count and frequency.
