How this service works
KYB Due-Diligence Pack ($0.05): one call merging company_lookup (SEC EDGAR + GLEIF LEI), sanctions_screen (OFAC SDN name + wallet), domain_intel (RDAP + DNS posture), wallet_profile (Base activity/balances/OFAC), and email_validate (syntax + live MX/DNS) into a single report with per-section status, sources, and a flags summary -- instead of a compliance/onboarding agent making up to 5 separate sub-cent calls and merging them itself. Only the sections implied by the body actually run, in…
Output
A single structured report with per-section results for: company identity (SEC EDGAR + GLEIF LEI data), sanctions screening (OFAC SDN name and wallet matches), domain intelligence (RDAP registration + DNS security posture), wallet profile (Base blockchain activity, balances, OFAC status), and email validation (syntax and live MX/DNS). Each section includes status, data sources, and a consolidated flags summary highlighting any compliance concerns.
Example use cases
Vendor onboarding compliance check
“Before we onboard GlobalTrade Ltd as a supplier, run a KYB check on them — their domain is globaltrade.com, contact email is partners@globaltrade.com, and their LEI is 549300EXAMPLE00000001. Flag anything suspicious.”
Crypto counterparty AML screening
“We're about to receive a large payment from wallet 0xDEADBEEF1234. Can you run a KYB pack on the sending company, DeFi Ventures, and check if that wallet has any OFAC flags or unusual Base activity?”
New client due diligence for financial services
“A new client, Pinnacle Holdings with ticker PNHL, wants to open an account. Pull a full due-diligence report — check their SEC registration, sanctions status, domain posture for pinnacle.com, and validate the email compliance@pinnacle.com.”

Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/kyb_pack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to run multiple compliance checks on a single business entity in one call rather than orchestrating 3-5 separate API calls yourself. It is ideal for onboarding workflows, vendor due diligence, and AML checks where you have a mix of identifiers (company name, domain, email, wallet) and need a unified flags summary. Prefer it over individual sub-endpoints when cost efficiency ($0.05 vs multiple calls) and latency matter, or when you want a single normalized report with consolidated status rather than merging raw responses yourself.
Side effects
- Company not found in SEC EDGAR or GLEIF — company_lookup section returns not-found status
- OFAC SDN API unavailable — sanctions_screen section returns error status with source noted
- Invalid or unresolvable domain — domain_intel section returns DNS failure
- Wallet address not found on Base or invalid format — wallet_profile section returns empty or error
- Email domain has no MX records — email_validate returns undeliverable status
- All optional fields omitted with no identifier provided — request rejected with validation error
- Rate limiting or upstream API timeout on one or more sub-services — affected sections return degraded status
