DOMAIN LOOKUP

Domain intelligence
in one request.

Use a single endpoint to resolve public DNS information and inspect the latest publicly logged TLS certificate information for a domain.

ENDPOINT

GET /v1/tools/domain/lookup

Pass a domain name using the domain query parameter.

DETAILED DOCUMENTATION

API reference for AI agents and developers.

DataBG tools are designed as small, machine-readable building blocks for automated workflows. Each request uses a predictable HTTP endpoint and can be accessed with an API key or, where enabled, through x402 machine payments.

DOMAIN LOOKUP API

Combine DNS and TLS intelligence for automated domain analysis

The DataBG Domain Lookup API combines public DNS information with publicly logged TLS certificate intelligence in one domain-focused operation. It is designed for AI agents that need a compact domain profile before continuing a research, security or enrichment workflow.

Request

GET https://api.databg.tech/v1/tools/domain/lookup?domain=google.com

Required parameter: domain — the domain to inspect.

Why combine DNS and TLS?

DNS records describe public domain infrastructure while certificate transparency data provides a separate view of certificate issuance. Combining the two signals gives an automated system more context than either lookup alone and reduces the need for an agent to orchestrate multiple domain utilities for a basic profile.

Useful domain intelligence

The tool is intended for public domain profiling, infrastructure research, security workflows, technical enrichment and agentic research. Agents can use the result to decide whether to call a dedicated DNS Lookup or SSL Certificate Check endpoint for deeper analysis.

Access and pricing

The listed price is $0.005 per request in USDC on Base Mainnet. The endpoint supports the DataBG machine-payment model, allowing a compatible client to receive a payment requirement and continue after settlement.

Related DataBG tools

For a DNS-only query, use DNS Lookup. For certificate-focused analysis, use SSL Certificate Check. For IP-level network intelligence, use IP Geolocation.

MACHINE PAYMENTS

How x402 access works

DataBG paid tools can use the HTTP 402 Payment Required flow. A compatible client requests a resource, receives machine-readable payment requirements, settles the requested amount in USDC on Base Mainnet, and retries the request with payment authorization. This model is designed for autonomous software that can discover and pay for individual API calls.
