## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability china-sourcing-certification-check-916d94af -d '<json body>'
```

Example prompt: What certifications do I need to import USB chargers from China into the US market? I want to know exactly which compliance docs to ask my supplier for before I send any payment.

## When to prefer this

Use this endpoint when you need a fast, structured lookup of which certifications a specific product type requires for either the EU or US market, particularly during supplier vetting before payment. Prefer this over general web search when you need actionable, structured verification steps rather than raw regulatory documentation. Best suited for pre-payment due diligence workflows where compliance verification is a gate before funds are released.

## Known failure modes

- Missing required fields (market or product_type) returns a validation error
- Unsupported market value (anything other than 'EU' or 'US') is rejected
- Vague or unrecognizable product_type may return generic or incomplete certification lists
- Payment failure or insufficient USDC balance blocks the call
- Upstream AI inference timeout may cause delayed or empty responses

## 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 an array of required certification names (e.g. CE, FCC, CPSC) relevant to the product type and target market, plus a step-by-step verification checklist to confirm those certifications are genuine before transacting with the supplier.
