How this service works
AI tools for vetting Chinese suppliers and import risk before money moves: factory-vs-trader verification, landed cost, payment red flags, audit checklist, certification checks, full audit chain. Pay-per-call in USDC on Base via x402.
Output
Returns a boolean status, a risk level enum (LOW, MEDIUM, or HIGH), a boolean indicating whether the company is a factory (true) or trader (false), and an array of human-readable risk signal strings explaining the assessment.
Example use cases
Pre-payment supplier fraud check
“Before I wire $40,000 to Guangzhou Hengda Hardware Co., Ltd., can you check whether they're a legitimate factory or a middleman and tell me if there are any payment red flags I should know about?”
New vendor onboarding risk screen
“We're onboarding a new Chinese supplier — Zhejiang Sunway Textile Co., Ltd. Can you run a risk check on them and tell me if they're LOW, MEDIUM, or HIGH risk and whether they're a factory or a trader?”
USCI number factory verification
“I have a USCI number from a Chinese company: 91440300MA5DXXXX23. Can you verify whether this is a real manufacturer or just a reseller, and give me any risk signals?”

Endpoint
POSThttps://x402-stable-door.lu7897859.workers.dev/verify_supplierWhen to prefer
Choose this endpoint when you need a fast, per-call, pay-as-you-go factory vs. trader verification and risk signal check for Chinese suppliers specifically — particularly useful before initiating payments or purchase orders. Prefer this over generic company lookup APIs when you need China-specific signals like USCI validation, factory registration status, and import payment red flags in a single call.
Side effects
- Company name not found in Chinese business registries — returns ok:false with empty signals
- Invalid or malformed USCI number — may return HIGH risk or error
- Ambiguous company name matching multiple entities — signals may reflect wrong entity
- Payment required but not received — 402 Payment Required response blocking the call
- Service unavailable or worker error — 5xx response with no data
