How this service works
Use before an AI agent pays a vendor or counterparty. Returns an action-oriented allow/review/block evidence preflight: legal-entity resolution, potential sanctions signals, RDAP domain evidence and company-domain consistency. x402 payment safety decision support only; not legal or transaction approval.
Output
A compact evidence result containing: legal entity resolution details, cross-source corroboration findings, sanctions screening outcome, RDAP domain registration evidence, and a domain/company-name consistency assessment. Intended as decision support only, not legal advice or transaction approval.
Example use cases
Vendor onboarding due diligence
“We're about to onboard GlobalTrade Partners at globaltraders.io as a new supplier — can you do a KYB check to verify their legal entity, screen them for sanctions, and check if their domain registration is consistent with the company name?”
Pre-payment counterparty screening
“Before I approve this invoice payment to NexaCorp Solutions at nexacorp.com, run a quick business counterparty check — I need to know if they're a real legal entity, if they're on any sanctions lists, and if the domain ownership lines up with the company.”
AI agent autonomous transaction guard
“My agent is about to execute a crypto payment to DataBridge Inc at databridge.io — first do a pre-transaction KYB check on them so I can see their sanctions status, legal entity evidence, and domain-company consistency before the funds go out.”
Technical details
Endpoint
POSThttps://agentkyb.andy229651.workers.dev/mcp-x402-payai-test?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a rapid, multi-signal pre-transaction KYB check on a business counterparty without integrating multiple compliance APIs separately. It is especially useful for autonomous agent workflows that must gate payments or onboarding decisions on a combined legal-entity, sanctions, and domain-consistency verdict in a single call. Prefer it over raw OFAC or RDAP queries when you need corroborated, cross-source evidence bundled into one response.
Side effects
- Unknown or unresolvable company name — insufficient public records to return entity evidence
- Domain not found in RDAP — returns partial result without domain evidence
- Ambiguous company name matching multiple legal entities — may return low-confidence or multiple candidates
- Payment failure — x402 payment not processed, endpoint returns 402
- Network timeout on external data source lookups — partial or degraded response
- Sanctioned entity detected — result flags match but does not block the transaction autonomously
