How this service works
Counterparty check in one call. Send a company or person name, a domain, an EVM wallet address, or any mix; returns one report with a status per check: OFAC sanctions (name and wallet), SEC EDGAR and GLEIF company records (name), domain registration, DNS and TLS, and email authentication (domain); each check that returns data cites sources and retrieval times. Use before paying or onboarding a party. A screening aid, not a compliance determination. Failed calls are not charged.
Output
A single JSON report containing one status entry per check performed: OFAC sanctions status for name and/or wallet, SEC EDGAR company records, GLEIF entity records, domain registration details, DNS records, TLS certificate info, and email authentication (SPF/DKIM/DMARC). Each check that returns data includes cited sources and retrieval timestamps. Failed calls are not billed.
Example use cases
Pre-payment vendor screening
“I'm about to pay a new supplier called 'Meridian Logistics GmbH' at meridian-logistics.de — can you check them for OFAC sanctions, pull their GLEIF and SEC records, and verify the domain looks legitimate before I approve the wire?”
Crypto wallet sanctions check
“Someone sent me a payment request from wallet 0xDEAD1234DEAD1234DEAD1234DEAD1234DEAD1234 — can you run a sanctions screen on that EVM address to make sure it's not on the OFAC SDN list before I send anything?”
New client onboarding due diligence
“We're onboarding a new client named 'Pharos Capital Partners' with domain pharoscapital.com — please screen their name against OFAC and check for SEC EDGAR registration, GLEIF data, and whether their domain's DNS, TLS, and email authentication all look clean.”
Technical details
Endpoint
POSThttps://quantagentshop.com/v1/counterparty-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single consolidated counterparty screening call that combines sanctions (OFAC), corporate registry (SEC EDGAR, GLEIF), and domain/infrastructure checks (DNS, TLS, email auth) in one request. It is purpose-built for pre-payment and pre-onboarding due diligence workflows where speed and source citation matter. Prefer it over individual lookup APIs when the counterparty may be identifiable by name, domain, and/or wallet address simultaneously, and you want a unified risk signal with cited sources rather than stitching together multiple APIs yourself.
Side effects
- At least one of name, domain, or address must be provided — omitting all three returns a validation error
- Invalid EVM address format (not matching 0x + 40 hex chars) returns a schema validation error
- Unreachable external data sources (OFAC, EDGAR, GLEIF, DNS) may result in partial results or timeouts for individual checks
- Malformed domain names may fail DNS/TLS lookups
- Network errors or upstream API failures return an error response and are not charged
