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.

SSL CERTIFICATE CHECK API

Inspect publicly logged TLS certificate information

The DataBG SSL Certificate Check API gives automated systems a way to inspect publicly logged TLS certificate information for a domain. It is intended for domain intelligence, security research, infrastructure analysis and monitoring workflows.

Request

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

Required parameter: domain — the domain whose publicly logged certificate information should be inspected.

Certificate intelligence

Depending on the available certificate record, the service can expose certificate status, validity information, issuer, Subject Alternative Names and expiration-related details. The data is sourced from publicly logged certificate information and should be treated as an intelligence signal rather than a substitute for a complete live TLS handshake.

Use cases

Useful applications include automated domain inventories, certificate monitoring, security research, infrastructure mapping, technical due diligence and AI agents that need TLS context before making a decision.

Access and pricing

The current listed price is $0.005 per request in USDC on Base Mainnet. Paid clients may receive HTTP 402 Payment Required and machine-readable payment requirements before the data response.

Important implementation note

Certificate transparency data describes certificates that have been publicly logged. Agents should distinguish certificate-log intelligence from the live certificate currently served by a host when a workflow requires real-time handshake validation.

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.
