KYB Agent API - Reprompt

Overview

The /v1/us-kyb/reports endpoint lets you generate a KYB report for a US business from a business name and structured address. Reports are generated asynchronously. Create a report request, poll /v1/us-kyb/reports/{request_id} until it completes, then read the structured report payload and pdf_url. Completed reports can include:

IRS and tax-ID matching
Secretary of State records
address and physical-presence signals
officers and watchlist context
web and social presence
operating-status and business-consistency signals

Use the JSON response for application logic, and pdf_url when you need a rendered report for analyst review.

The response shape depends on the status field: processing, completed, or error. When status is completed, the response includes the full report object and a pdf_url pointing at the generated PDF in S3. Completed responses remain available for later polling. In production, I verified the same completed request still returned 200 more than 5 minutes after completion.

What the Report Covers

Each completed report returns a report object that may include sections like:

Section	What It Tells You
`report`	Business status and last-updated timestamp
`scores`	Reprompt-generated scoring outputs
`submitted_information`	Submitted business name, tax ID, and office address with verification status
`business_information`	Entity-level attributes like formation state, entity type, and tax-ID fields
`sos`	Secretary of State search results, status counts, and filing records when found
`insights`	Per-section rollups for SOS, address, watchlist, TIN, and formation-state checks
`business_names`	Known legal or alternate names
`online_presence`	Website and social signals when available
`office_addresses`	Address records returned by the report pipeline
`people`	Officer or principal names when identified

The exact fields present in report can vary by business, source coverage, and confidence level. Use defensive parsing rather than assuming every section or field will always be populated.
