How this service works
Pre-transaction business counterparty check for AI agents. Combines legal-entity resolution, cross-source corroboration, sanctions screening, RDAP domain evidence and domain/company-name consistency into one compact evidence result. Decision support only; not legal or transaction approval.
Output
Returns a compact evidence result with an action-oriented recommendation (allow, review, or block), legal entity resolution details, cross-source corroboration data, sanctions screening outcome, RDAP domain ownership evidence, and a company-name/domain consistency assessment.
Example use cases
Vendor payment safety check
“We're about to wire $50,000 to GlobalTech Supplies Ltd at globaltechsupplies.com — can you run a KYB check on them to see if they're sanctioned or if something looks off before we approve the transfer?”
New supplier onboarding due diligence
“I'm onboarding a new supplier called Meridian Logistics Inc, their domain is meridianlogistics.io — can you check whether their legal entity is legit, if the domain matches the company, and whether they're on any sanctions lists?”
Agent-initiated payment guardrail
“My AI agent is about to pay an invoice from CloudBridge Analytics at cloudbridge-analytics.com — screen them first and tell me if I should allow, flag for review, or block the payment.”
Technical details
Endpoint
POSThttps://agentkyb.andy229651.workers.dev/mcp-x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a pre-transaction due diligence signal on a business counterparty — especially before executing a payment — and requires a single, consolidated allow/review/block recommendation combining legal entity resolution, sanctions screening, and domain consistency in one call. Prefer this over manual lookup tools or individual sanctions-check APIs when speed and multi-source corroboration matter for agentic payment workflows.
Side effects
- Unknown or unresolvable business name returns inconclusive evidence
- Domain not found in RDAP returns missing domain evidence
- Network timeout or upstream data source unavailability returns error
- Ambiguous company names with multiple matches may return low-confidence results
- Sanctioned entity detected triggers block recommendation
