⭐ ProvenExpert Scraper — DACH Business Leads with Email, Phone & Impressum

Turn ProvenExpert into a German, Austrian and Swiss B2B lead list. Type a trade and a German city — Steuerberater in München, Dachdecker in Hamburg, Handwerk in 10115 — and get one row per business with the contact data outbound teams actually dial and mail: email, phone, mobile, fax, website, Impressum link, named contact person and full address — plus rating, rating count, recommendation rate, industry, geo coordinates and whether the owner has claimed the profile.

ProvenExpert shows a Kontaktdaten block and an Impressum link on business profiles, which is why the contact fill below is so high.

Measured, not estimated: on a 2,738-business search (every Handwerk business ProvenExpert lists in Berlin) this Actor delivered 2,738 of 2,738 listed businesses, 91% with an email, 100% with a website, 89% with an Impressum — and billed 2,738 events for 2,738 rows (a repeat run on the final build: 2,733 of 2,738, 2,733 billed). $6.50 per 1,000 leads, no login, no proxy needed.

💡 What does this Actor do?

It reads ProvenExpert the same way the site does, in three modes:

In search mode the Actor uses ProvenExpert's own directory API. That API returns results in a slightly different order on every request, so a single pass over the result pages misses about 6% of a large result set and repeats others. This Actor re-sweeps until it has collected every business the site says it lists (measured on Handwerk / Berlin: pass 1 = 2,585 unique, pass 5 = 2,738 of 2,738; two live runs collected 2,738 and 2,733 of 2,738) and reports the site's own total next to what it collected, per search, in RUN_SUMMARY.

📊 Field fill — measured on real runs

Three frames, because one sample describes a sample, not the directory. Contact fields first.

What the table says, plainly: email and website are near-universal; a landline is on roughly one profile in four in the directory search and one in two across the whole sitemap. Use requirePhone if you only want businesses you can call. Most directory profiles are unclaimed profiles ProvenExpert built from public data, which is also why the recommendation rate is rare. The last column is why we quote ranges: read in sitemap order, a shard starts with old profiles the owners set up themselves — far more phones, mobiles and named contact persons, far fewer ratings.

Sitemap sweep with a country filter: in one shard (6,643 URLs, 2,701 German-language), 30 Austrian and Swiss businesses came out of 237 profiles examined — Austria and Switzerland are ~7–13% of the German-language directory, so an AT/CH sweep reads many German profiles to find them (you are only charged for the ones delivered).

💰 Pricing

Pay per event: $0.0065 per business lead ($6.50 per 1,000). No start fee, no monthly fee.

You are charged only for a business that is delivered to your dataset and publishes at least one way to reach it (phone, mobile, email or website), once per profile per run. You are never charged for: profiles without any contact (skipped, or delivered free with onlyWithContact: false), profiles that no longer exist, profiles we could not reach, duplicates, or rows your filters removed. Rows are charged as they are delivered, so a run that hits your spending cap stops with every delivered row paid for and nothing unpaid in your dataset.

🔁 Run summary

Every run writes RUN_SUMMARY to its key-value store: delivered and billed counts, the three kinds of "nothing" kept apart (profile gone · exists but publishes no contact · unreachable after retries), and for every search the site's own total, how many unique businesses were collected and in how many passes. A search whose collected count falls short of the site's total is marked complete: false and named in the run's status message.

❓ FAQ

Can I search Austria or Switzerland? Not with search — ProvenExpert's directory search only recognises German places and answers "location not found" for Wien or Zürich (the Actor tells you so in the status message instead of failing). Use mode: "sitemap" with countries: ["AT", "CH"]: Austrian and Swiss businesses live in the de-de section of the site.

Why do I get fewer landlines than emails? Because that is what businesses publish on ProvenExpert: measured 26.6% landline vs 91.1% email on 2,738 Berlin craft businesses. We never fill a missing phone from anywhere else.

Why is fetchProfileDetails on by default when the directory already has an email? Because the directory API's email is the account email, not always the published contact. On 2,738 Berlin profiles, 222 profiles showed no email on the page but still had one in the API — 218 of those did not match the business's own domain (five were the Handwerkskammer Berlin's info@, two were example.com). On 62 Hamburg roofers showing an email on both, 3 disagreed and the API side was the managing web agency's address. With details on, every email you get is the one on the public profile. With details off, emails come from the API and fieldSources.email says searchApi.

Where does the Impressum come from? From the profile's Kontaktdaten block: usually a link to the business's own Impressum page (impressumUrl); for ~1% the business typed it into ProvenExpert and we return the full text (impressumText).

What is isClaimed? ProvenExpert creates profiles from public data for businesses that never signed up.

isClaimed: false

Why is recommendationRate usually null? It exists only for ratings collected on ProvenExpert itself. For profiles whose ratings are all imported (most of them), the site prints "Empfehlungsquote : 0%" as a placeholder — returning that as 0% would tell you every customer refused to recommend them.

Why does a search for München return businesses in Oberhaching? Because ProvenExpert lists businesses that serve a place, not only those inside it — even at radius 0. Measured: Steuerberater / München 26 of 39 with a München address; Dachdecker / Köln 51 of 139; Handwerk / Berlin 2,050 of 2,738. Turn on onlyInSearchedCity to keep only the ones inside; the check uses the directory's own address before the profile is opened, and nothing filtered is charged.

How do I get every business in a big city? Set maxResults: 0. The Actor pages through everything and re-sweeps until it has every business the site lists; Handwerk / Berlin (2,738 businesses) took about 6 minutes.

Are the phone numbers normalised? No. phone is exactly as the business shows it and phoneDialable is the page's own tel: link. We never rewrite, complete or guess a number.

Can it scrape the reviews themselves? No — this Actor is built for contact leads. It returns the rating, counts, recommendation rate and top competencies per business, not individual review texts.

Does it need a proxy or a login? Neither. ProvenExpert has no anti-bot wall today and all data is public. If that ever changes, switch the Proxy input to Apify Proxy with the RESIDENTIAL group selected (a proxy with no group chosen is not available on every Apify plan).

How fresh is the data? Live: every run reads ProvenExpert at run time. profileLastUpdated tells you when the business last edited its profile.

⚠️ Data limits

• Search is Germany-only by the site's design; AT/CH need the sitemap sweep, which reads many German profiles to find them.
• industries, tagline, description, geo and lastRatedAt come from the directory search and are empty in sitemap and profiles mode (the profile page does not carry them).
• Landline fill is ~27% in the directory search — that is the source, not the parser (checked: every profile page carrying a phone icon produced a phone, 116 of 116 across three shards).
• The directory search lists only the part of ProvenExpert that is enrolled in its search (e.g. 39 tax advisors for Munich); the sitemap covers the whole public directory (~1.7M URLs across all languages).
• fax is unlabelled on ProvenExpert; we verified the meaning against one business's own Impressum.
