How this service works
When you need the whole picture of one company before you sign, onboard, pay or acquire, call the entity file: ONE answer holding identity and standing, the registered office, SIC activity and previous names, the filing position, a sanctions screen across four lists, and the ownership chain to the ultimate parent — with ONE coverage block naming every register consulted and every one not. One call and one receipt instead of four. Unknown is a first-class answer.
Output
A structured JSON receipt containing: the entity's verified identity and registration status, registered office address, SIC activity classification, all previous company names, current filing position, sanctions screening results across four named lists (with explicit pass/fail/unknown per list), the full ownership chain to the ultimate parent entity, and a coverage block naming every register consulted and every register not consulted. 'Unknown' is returned as a first-class answer where data is unavailable rather than being omitted.
Example use cases
Pre-contract supplier onboarding check
“We're about to add Meridian Logistics GmbH as an approved supplier — before I send the contract, pull their complete entity file including sanctions screening and ownership chain so I can confirm there are no red flags.”
Acquisition target due diligence
“We're considering acquiring Brightstone Ventures Ltd (company number 11234567 registered in England). Can you get me their full due diligence dossier — identity, registered office, filing position, any past names, sanctions status across all four lists, and who ultimately owns them?”
Compliance check before international payment
“I need to pay invoice from Solaris Trading Co before I authorize the wire transfer, can you screen them against sanctions lists and verify their legal standing and ownership structure so we're covered for compliance?”

Endpoint
POSThttps://factstamp.agentrails.workers.dev/entity-file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call due diligence package on a legal entity before a high-stakes action — signing a contract, onboarding a supplier, authorizing a payment, or initiating an acquisition. It is superior to calling individual registry, sanctions, and ownership APIs separately because it aggregates four sanctions lists and the full ownership chain in one response, explicitly documents every register consulted (and every one not consulted), and treats 'unknown' as a first-class answer rather than a silent gap. Prefer it over basic entity existence checks when compliance coverage and beneficial ownership visibility are required.
Side effects
- Entity not found in any consulted register — returns unknown status with coverage block listing registers checked
- Ambiguous company name with multiple matches — may require registration number or jurisdiction to disambiguate
- Sanctions list temporarily unavailable — partial result returned with explicit gap in coverage block
- Invalid or malformed company identifier in request body — returns validation error
- Upstream register API timeout — coverage block will flag the register as not consulted
