Domain feed: daily new and deleted domains

What it is

Hundreds of thousands of domains are registered and deleted every day. This feed gives them to you ready to query: which domains appeared or disappeared on a date, in which TLD, and which ones contain the words you care about.

Use it to monitor brands (registrations similar to your name), investigate phishing campaigns or feed your own security analysis. The data may not be used for marketing or to send commercial messages.

It covers more than 1,000 gTLDs, with hundreds of thousands of new domains a day. A domain counts as new on the day we first detect it, usually because it was registered the previous day: in the samples we have checked against WHOIS, the creation date matches that day.

The sync starts at 07:00 UTC and currently takes about 25 minutes, so the previous day’s changes are usually available around 07:30 UTC. This is a typical timing, not a guarantee.

What’s included

• New and deleted domains by date (/v1/added, /v1/deleted), filtered by TLD, keyword, IDN and date range. The keyword is matched against the name without the TLD and supports OR (|) and a wildcard (%).
• One domain’s history (/v1/history): every time it appeared or disappeared.
• Keyword statistics (/v1/keywords).
• Per-TLD statistics (/v1/tlds): domain counts and the latest additions and deletions of each.
• Daily ZIP (/v1/dailyzip/) with every new or deleted domain of a day.

Responses are JSON. Send your key in the Authorization: Bearer header, never in the URL. The limits of each plan are published in the table below.

Documentation: every endpoint with its parameters and examples, plus getting started and errors.

Without a wildcard, the keyword must match the name exactly; with % it matches anything containing it. In a URL, % is written %25: the example returns the domains whose name contains “bank”.

curl -H "Authorization: Bearer <your key>" "https://api.cifradia.com/v1/added?kw=%25bank%25&tlds=com,net"
