# ChinaCheck

> Due-diligence reports on mainland-China (PRC) companies. Search and a free
> registration snapshot are open and anonymous; paid reports (risk, judicial,
> ownership, intellectual property) are delivered as a translated PDF after
> Stripe payment.

ChinaCheck is callable by AI assistants two ways:

## Model Context Protocol (recommended for Claude / ChatGPT / Gemini)

- MCP endpoint (Streamable HTTP): https://www.china-check.com/api/mcp/mcp
- Tools: `search_chinese_company`, `get_company_snapshot`, `start_report_purchase`
- Setup guide (add to Claude / ChatGPT): https://www.china-check.com/en/connect

## REST API (for GPT-Actions / OpenAPI import)

- OpenAPI 3.1 spec: https://www.china-check.com/openapi.json
- GET /api/v1/ai/search?q={name}&language={iso} — search companies
- GET /api/v1/ai/snapshot?companyId={id}&language={iso} — free snapshot + paid-report quote
- POST /api/v1/ai/purchase — start a paid report purchase, returns a Stripe Checkout URL

All responses use the envelope `{ "ok": boolean, "data"?: ..., "error"?: { "code", "message" } }`.
Endpoints are anonymous and per-IP rate-limited. Report tiers: BASIC_INFO ($19.90),
RISK ($149.90), DUE_DILIGENCE ($249.90).

## Notes for agents

- Paid purchases require the buyer's email (the report PDF is sent there) and an
  explicit compliance acknowledgement (legitimate-use / no-misuse of personal data).
- Free-text fields in snapshots may be in Chinese; translate as needed.
