Everything Behind a Domain, in One Call
Registrar and registrant, domain age, MX and nameserver records, SPF and DMARC policy, catch-all status, website title and detected tech stack — returned as structured JSON from a single request. Free tier included, no credit card.
Most enrichment APIs return a company name and a logo. This one returns the infrastructure — the part that tells you whether a domain is real, who operates it, and whether mail sent to it will arrive.
They answer different questions, and most teams eventually need both.
Domain enrichment — this API — takes a domain and tells you about the domain: who registered it, when, what runs its mail, how its DNS is configured, whether it is a parked shell or a working business. Use it to score signups, spot fraud rings sharing infrastructure, qualify inbound leads by company footprint, and decide whether an address is worth sending to at all.
Contact enrichment takes an email address and tells you about the person and company attached to it — company name, industry, size, role signals. Use it to personalise outreach and fill CRM gaps.
Both run off the same single API call, so enriching a domain and validating an address on it is not two integrations. If you only need the verdict on an address rather than the full record, the email validation API is the lighter endpoint. To try the data before writing any code, the free email enrichment tool and the mail server lookup both run without an account.
A domain registered eleven days ago, behind a registrar with no registrant details, resolving to shared hosting, with no DMARC — that is a pattern, and it is visible before the account is created. Pair it with signup protection.
Filter inbound by real company footprint instead of guessing from the email domain. Corporate mail platform, aged domain, enforced DMARC and a live site is a very different lead from a free-provider address.
Before a send, know which recipient domains enforce DMARC, which sit behind hard filtering, and which are catch-alls that will silently swallow the message. Relevant to cold outreach and to list cleaning.
Hundreds of unrelated-looking domains often share one MX host, one A record or one nameserver hash. Domain enrichment exposes that shared infrastructure, which is how you catch the second, third and fortieth account.
