NERDTOOLS / DOMAIN DIAGNOSTICS

DEVELOPER WORKFLOW / REST + JSON

Domain enrichment API, ready for production workflows.

Enrich domain records with structured public DNS, registration, certificate, IP, reputation, web, and email-security signals.

Current programmatic coverage: The Free and Pro developer plans expose the same diagnostic catalog. Plans differ by quota and rate limits.

01 /

Build a bounded public domain profile.

Combine independent public signals for customer onboarding, support triage, asset inventory, lead qualification, and risk context.

  • Resolve addresses and registration evidence.
  • Inspect certificate identity and validity.
  • Add IP, reputation, and selected network context.
  • Read web response, redirect, metadata, and email-security signals.

02 /

Model provenance and partial coverage.

Enrichment sources change independently. Production consumers should retain timestamps, source-level success, and unknown values instead of collapsing every response into one permanent classification.

  • Use stable domain identifiers and normalized hostnames.
  • Store observation time and tool coverage.
  • Handle individual source failures without discarding successful evidence.
  • Refresh fields according to how quickly each public signal changes.

FAQ /

Operational detail.

Can I evaluate the API for free?

Yes. The free plan supports evaluation and small workflows with the same endpoint catalog as Pro.

Are REST and MCP separate products?

They share the same account, API key, diagnostic capabilities, and quota model.
