How this service works
Decision-ready public-evidence due diligence for a company, vendor or counterparty. Returns cited findings, material risks, conflicting claims, freshness and validation evidence, plus a locally verifiable hash-bound delivery receipt.
Output
A structured JSON object containing cited public-evidence findings, identified material risks, conflicting or disputed claims, freshness and validation metadata indicating how current the evidence is, and a locally verifiable hash-bound delivery receipt confirming the integrity of the response.
Example use cases
Pre-contract vendor risk check
“Before we finalize this SaaS vendor agreement, can you pull a due diligence brief on CloudStack Solutions (domain: cloudstacksolutions.io, UK jurisdiction) for the past 90 days? I want to know about any legal disputes, data breaches, or regulatory issues, with sources cited.”
Startup investment due diligence
“We're considering a seed investment in NovaTech AI — can you research them (company name: NovaTech AI, domain: novatechai.com, Delaware jurisdiction) over the last year and flag any material risks, founder controversies, or conflicting public claims I should know about?”
International counterparty screening
“I'm about to sign a distribution deal with a company called MedSupply GmbH in Germany — can you run an evidence brief on them focusing on regulatory compliance and financial stability for the past 180 days, and tell me if there are any red flags or disputed claims in public records?”
Technical details
Endpoint
POSThttps://api.x402-engine.com/v1/company-due-diligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, cited, conflict-aware due diligence on a specific company, vendor, or counterparty rather than a general web search. It is particularly valuable when you need material risk identification, conflicting-claims detection, and a verifiable hash-bound receipt for audit purposes. Prefer this over generic search tools when you need decision-ready intelligence with provenance and freshness guarantees rather than raw search results.
Side effects
- Insufficient public evidence found for obscure or newly formed companies
- Ambiguous company name matches multiple entities — may require domain or jurisdiction to disambiguate
- Stale evidence if freshness_days threshold cannot be met by available sources
- API returns error if neither company_name nor domain is provided
- Rate limits or payment failure via x402 protocol blocking the request
