Frequently asked questions

webatla is a global domain database. We crawl, classify and enrich data on every active domain on the web — 407.5 million of them — and ship the result as structured JSON Lines datasets (zstd-compressed) you can download and process yourself.

There's no query UI to log into — you buy a dataset and download the file, or pull it programmatically via the download API.

Mostly four kinds of teams:

• Research & data — analysts, ML teams, academic researchers measuring the web
• Growth & sales — building lead lists ("every Shopify store in Germany")
• Security & threat intel — tracking lookalikes, new registrations, risky tech stacks
• Domain investors — finding expiring domains with traffic and rank

Every dataset has a free 10,000-row sample download. Same schema as the full file, no signup required. Browse the datasets to grab a sample.

Immediately. The download link is on the order confirmation page and emailed to you within seconds. Datasets larger than 10 GB stream as you download — no waiting for an export job.

Six core datasets plus one special offer:

• All active domains · €29 · 407.5M rows
• Active websites + Ranking · €99 · 307.8M rows
• Technologies · €159 · 270.8M rows
• DNS · €199 · 345.2M rows
• RDAP & WHOIS · €299 · 380.6M rows
• All data · €599 · 407.5M rows · everything
• Domain Investor · €299 · expired + expiring domains with rank

Full details on the pricing page.

Every day we generate a fresh export of every dataset. Inside your access window you can always download the latest version.

We combine multiple sources:

• Public zone files for every TLD that publishes them
• Active DNS resolution against our own resolvers
• Public RDAP and WHOIS endpoints
• Our own crawler for technology fingerprinting (HTTP headers, HTML markers, JS heuristics)
• Public ranking signals (PageRank, Harmonic Centrality)

For widely-deployed platforms (WordPress, Shopify, Cloudflare, Google Analytics) we measure precision around 99%. Long-tail and self-hosted tools sit at 92-95%. False positives almost always come from white-label resellers running the same fingerprint.

Sizes vary by dataset and grow over time, so we don't pin fixed numbers here — the current compressed size is shown on each dataset's page and on the checkout screen.

Files are JSON Lines, zstd-compressed (.jsonl.zst); decompressed they are several times larger, so plan disk accordingly.

The free 10,000-row sample (plain .jsonl) shows the exact schema, and the full column reference with data types lives on your API page. Column names are stable; new columns are appended (never re-ordered) so your loaders don't break.

Correct. Every dataset is a one-time purchase. We don't auto-renew, and we don't keep a card on file unless you explicitly opt in. Your access expires automatically and you choose when to renew.

From the moment of purchase you have one calendar month during which you can download the dataset — including every daily fresh export published in that window — as many times as you want. When it expires the download link stops working.

Same model, longer window. You pay 10× the monthly price and get a full year of access — saving 2 months versus renewing each month. Still one-time, still no auto-renewal.

Credit and debit cards (Visa, Mastercard, Amex), Apple Pay, Google Pay, SEPA direct debit and bank transfer (for orders over €500). All processed via Stripe.

No. The datasets are digital products and all sales are final. That's why every dataset ships with a free 10,000-row preview — exact same schema and quality as the full file — and we ask you to confirm at checkout that you've reviewed it. Once payment goes through, the download link is delivered immediately.

The only exception is a material defect — wrong schema, a corrupted or malformed file, more than 5% of rows missing vs the advertised count. In that case email support@webatla.com within 72 hours and we'll either re-issue or refund.

Under EU law (§312g(2)(13) BGB) the 14-day withdrawal right doesn't apply to immediately-delivered digital content that you expressly consented to receive. Checking the preview-reviewed box at checkout is that consent.

Yes — pay in crypto (BTC, ETH, USDT and more) via our crypto checkout. Access unlocks automatically once the payment confirms.

For bank transfer or invoice-then-pay on larger orders, contact us.

Each dataset is a separate purchase, so moving to a different one is a new purchase — there's no in-place upgrade credit.

Buying the same dataset again while access is still active renews it: the new month is added on top of your remaining time, so you never lose days.

Yes. Add your company name and VAT ID in Billing → Invoice details before purchase, and every future invoice will be issued correctly. We can also re-issue past invoices on request.

Yes for EU customers without a valid VAT ID. EU B2B customers with a verified VAT ID are reverse-charged. Non-EU customers are charged net.

JSON Lines, zstd-compressed (.jsonl.zst) — one JSON object per line. The free 10K sample is plain, uncompressed .jsonl. That's the only format; there's no CSV or Parquet.

A signed HTTPS download, resumable, valid for your whole access window. You can pull the full dataset or just one slice — a single TLD, TLD suffix, country or technology.

The same files are reachable programmatically via the download API with your key.

Yes. Files are JSON Lines (newline-delimited JSON) — decompress with zstd and load as NDJSON. BigQuery, Snowflake and DuckDB ingest JSONL directly; for Postgres, load each line into a jsonb column or flatten with jq first.

Yes — a download API, included with every dataset at no extra cost. Use a Bearer key from your account to pull the full file or a per-scope slice (one TLD, suffix, country or technology). There's no separate query/lookup API — for filtered work, download the relevant slice and filter locally. Full docs at your API page.

Yes. Add a webhook in Account → API keys → Webhooks and we POST a dataset.updated event each time the daily export refreshes, listing which datasets changed. Your job then pulls the fresh file via the download API.

Yes. We only include publicly available WHOIS, RDAP and DNS data. Personal data is redacted where the registrar requires it (per GDPR Art. 6 / 14 / EDPB guidance). A Data Processing Agreement is available on request — included by default for All-data customers.

You can use it for prospecting and research, but you're responsible for your own outreach legality (CAN-SPAM in the US, GDPR Art. 6 in the EU, etc.). We don't include personal email addresses in our datasets — only registrar-provided contact channels and abuse contacts where they're public.

Internal use within your company is fine. Redistribution, reselling, or building a competing product on top of our data is not — see the Terms of use. If you have a use case in mind that needs redistribution rights, talk to sales.

Use the password reset flow. We'll email a one-time reset link (valid 30 minutes). Resetting your password doesn't affect your dataset access or your active sessions.

Yes. Invite up to 5 teammates from Account → Settings → Team on any plan. Each member gets their own login but shares the same dataset access and download history.

From Account → Settings → Danger zone. Deletion is permanent and removes downloads history, API keys and saved card. Active dataset access continues until expiry — we don't refund unused access on deletion.
