DEVELOPER DOCUMENTATION

Before your first API request

The production API base URL, authentication contract, and account provisioning are not connected to this website. Start with the actual published contract when the API launches.

Choose a workflow

Decide whether the task needs an immediate individual result or a longer-running bulk job. Keep a clear separation between sample responses and actual checks.

Choose a workflow

Use an interactive check for one address only when the user can receive timely feedback. Use a background job for lists. Decide the destination fields before implementing the request.

Define the minimum record

Keep your internal record ID, original address, result category, reason, and check time. Store request references separately from user-facing labels.

Prepare for launch

Confirm the production base URL, authentication scheme, request limits, result schema, and charging policy. This documentation currently describes integration principles; it is not an executable API contract.

Before you enable this workflow

ConfirmWhy it matters
Production contractUse documented fields, limits, and supported operations.
Failure policyDecide what the application does when a check cannot complete.
Data boundariesKeep credentials and customer data out of unnecessary logs.
