How this service works
86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.
Output
A JSON object containing: verified company details from GLEIF (LEI, legal name, status, legal form, jurisdiction, founding date, registered address), VAT validation result, sanctions screening outcome with match list, domain registration data (created/expiry dates, registrar, DMARC policy, mail servers, email security grade), website technology stack, a list of recent news articles, and a checks summary showing which sub-checks passed or failed.
Example use cases
Vendor onboarding due diligence
“Before we onboard this new supplier, run a KYB check on 'Acme GmbH' in Germany — I need their LEI, whether they're on any sanctions list, and their domain security info for acmegmbh.de. Show me up to 3 recent news articles too.”
EU VAT number validation with company enrichment
“We received an invoice from a company claiming VAT number FR12345678901 — can you validate that VAT number and pull their full company profile including sanctions screening and legal address?”
Financial counterparty screening
“We're about to wire funds to a company called Nexum Capital Partners — can you screen them for sanctions exposure, confirm their legal status using their LEI if you can find it, and get me any news from the last month?”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/company-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call comprehensive KYB bundle rather than calling individual company lookup, sanctions, VAT, and domain endpoints separately. Ideal for compliance workflows, vendor onboarding, counterparty screening, and business due diligence where you need GLEIF-sourced legal entity data combined with sanctions screening and domain security in one response. Prefer over individual GLEIF or VAT APIs when you need the full enriched picture at once.
Side effects
- Company name not found in GLEIF — returns empty or low-confidence candidates
- VAT number invalid or country doesn't return names (e.g. DE) — partial result returned
- Domain not registered or unreachable — domain/website checks marked as failed
- Sanctions database temporarily unavailable — sanctions check may be skipped
- Ambiguous company name with multiple candidates — top match returned with other_candidates list
- Missing required parameters (no name, LEI, or domain provided) — request rejected

| news_limit | integer | Number of news articles, 0 to skip |
