CN Evidence provides structured Chinese company registration and recorded-risk information for supplier workflows. It does not decide whether a supplier is safe to pay.

No signup, wallet or live query. The Standard sample is an identity-redacted editorial extract of a historical internal acceptance, not a customer case or the full original report. The older fictional Basic example remains separate.
先看实际内部验收报告的脱敏摘录，再决定是否接入；这不是客户案例，没有记录不代表没有风险。
Standard screening-standard-v1: 0.29 USDC, ten fixed Jinghai-first check dimensions, with JSON and Chinese/English HTML reports. Only when administrative-license check v3_license_list has a connection/call failure or is already circuit-open, one QCC get_administrative_license fallback is made (3 points, up to 100 records; no paging or retry). Enhanced screening-enhanced-v1: 0.59 USDC, the same ten dimensions plus one QCC qualifications lookup (up to 30 records), at most two QCC calls total. The license fallback preserves both source outcomes but does not claim complete records; no other check falls back and this is not fallback across all 64 tools. Other check failures or failure of both providers prevent settlement. QCC qcc-qualifications-v1: 0.03 USDC, canonical JSON only, up to 30 records, no report analysis. Screening reports also support get_china_company_report through the MCP facade over the same HTTP x402 checkout; QCC-only qualifications remain HTTP-only. Free MCP options and recovery tools are available. On 2026-10-15, one owner-funded 0.29 USDC Standard MCP test via the public Python example returned all ten contracted dimensions in 15.78 seconds, reconciled exactly one settlement, exercised the QCC administrative-license fallback, and recovered identical JSON plus both HTML languages without new provider calls or payment. This was not complete due diligence; the decision remained insufficient_evidence and this was not customer traction. The current Enhanced and Resilient contracts have no funded acceptance. No funded acceptance covers the complete 64-tool catalog; the separately documented HTTP v3_company_detail test does not establish acceptance of that full catalog. Delivery depends on provider balance and runtime availability; check live status before purchase. There is no manual daily or total commercial quota, but single-order limits and delivery conditions still apply. See product details, conditions and current acceptance status.
标准筛查0.29 USDC：10个固定维度，优先查询鲸海。仅当行政许可工具（v3_license_list）连接/调用失败或已熔断时，才调用一次企查查 get_administrative_license（3积分、最多100条，不翻页、不重试）。增强筛查0.59 USDC：同样10个维度，另始终查询一次企查查资质（最多30条），企查查最多调用两次。许可回退保留两个来源结果，但不声称记录完整；其他检查不回退，也不是全部64个工具均有兜底。其他检查失败或两家服务商均失败时不结算。报告支持JSON及中英文HTML；单独企查查资质0.03 USDC，仅规范JSON、最多30条、不含报告分析。整份筛查报告也可用 get_china_company_report，经 MCP 转接同一 HTTP x402 结算链路；企查查资质单项仍仅支持 HTTP。另有免费套餐查询及原单恢复工具。2026-10-15，一次由所有者出资的0.29 USDC标准版MCP测试通过公开Python示例完成，15.78秒返回全部十项合同范围内容，核对为恰好一次结算，触发企查查行政许可回退，并恢复出相同JSON及中英文HTML，未新增服务商调用或付款。该报告不是完整尽调，结论仍为 `insufficient_evidence`；这是内部测试，不代表客户需求。当前增强版、韧性版合约尚无实付验收；尚无实付验收覆盖完整的64工具目录，另有记录的一次 v3_company_detail HTTP 测试不代表完整目录通过验收。交付依赖服务商余额和运行可用性，以实时目录为准。没有人工日或总商用额度限制，但仍受单笔限制且不保证交付。详情、条件和当前验收状态见产品说明。

# CN Evidence — China supplier information API (v2 legacy packages)
The Basic/Full package descriptions below are legacy package scope, not the full current catalog. Current V3 offers 64 individual data tools at 0.011 USDC per call. On 2026-10-10, one owner-funded HTTP v3_company_detail purchase passed payment, settlement, delivery and free recovery checks. This is not a customer sale or paid acceptance of all 64 tools or the V3 MCP transport. Delivery depends on provider balance and runtime availability. No automatic repayment or upstream business retry; save a recovery token before purchase. See V3 failure and recovery guidance and the live catalog.
Paid lookup / 查询收费： Adding MCP alone does not enable payment. Buyers need a payment client, Base USDC wallet and spending authorization.

CN Evidence provides structured Chinese company information for supplier verification and due diligence. The old local procurement/regulatory dataset is retired from active service. Existing API URLs and MCP tool names remain available.
## Pricing and coverage
| Package | USDC per successful report | Included modules |
| --- | --- | --- |
| Legacy Basic | 0.032 | Registration, operating abnormalities, administrative penalties |
| Legacy Full | 0.093 | Basic plus serious violations, enforcement, dishonesty, bankruptcy, qualifications, customs |
One interface can return many fields and records: Full means nine modules, not nine fields. Each list is limited to its first page, up to ten records. Serious violations, enforcement and dishonesty use the current-status option. No automatic historical queries, pagination or retries.
Upstream nominal costs are CNY 0.15 / 0.45. Prices use a fixed budgeting assumption of 7 CNY/USDC and upward rounding; this is not a live FX quote. Trial credits do not lower the published retail prices.
## Existing entrypoints
- [x402 API](https://api.cnevidence.com)
- [Live OpenAPI](https://api.cnevidence.com/openapi.json)
- [Agent manifest](https://api.cnevidence.com/.well-known/agent.json)
- [x402 discovery](https://api.cnevidence.com/.well-known/x402)
- [Remote MCP](https://mcp.cnevidence.com/mcp)
Basic: GET /x402/cn/supplier/evidence/basic?uscc=YOUR_USCC
Full: POST /x402/cn/supplier/evidence with JSON {"uscc":"YOUR_USCC"}
Alternatively supply the exact Chinese legal company name as "company".
MCP tools: get_china_supplier_evidence_basic (query) and get_china_supplier_evidence_full (request). Both accept an identity object containing company or uscc.
Payment: x402, USDC on Base. Unsigned requests return payment requirements without querying data providers. A funded compatible wallet and explicit spending authorization are needed to buy a report. Native MPP is temporarily paused. The old the402 webhook is paused pending repricing; use the canonical x402/MCP entrypoints.
## Response and limitations
Schema v2 returns schema_version, request_id, tier, provider, queried_at, entity, modules, coverage, usage and limitations. Each module describes its status, data/records and paging uncertainty. Unselected modules are marked not_requested; no_records means only that this query returned no records.
Free entity resolution is retired. The legacy free HTTP resolve route remains a capability notice; the existing resolve_china_company MCP tool now offers local input preflight only, not a database lookup. Free HTTP input preparation: POST https://api.cnevidence.com/free/cn/identity/preflight with company or uscc. input_ready does not mean verified identity; no upstream call or payment occurs. Static examples are schema guides, not live supplier facts. Procurement award history is NOT included in these nine interfaces. Legacy include_evidence/evidence_limit options do not expand coverage; package limits apply.
Data availability depends on provider coverage and update schedules. Preserve any source attribution included in query results. Absence of records is not proof of no risk. No nationwide completeness, fraud score, payment-safety guarantee, bank verification or legal conclusion is provided.
## 中文摘要
当前 V3 提供 64 个单独计费数据工具，每次选定工具调用 0.011 USDC，MCP 共 71 项定义（其中3项为新增报告流程工具）。完整工具范围、参数和限制见 https://yangchunhong3000.github.io/cn-evidence-public-docs/v3-tools.html 。买方指南提供 V3 企业详情购买示例，并非全部工具的通用购买客户端。
标准筛查报告 `screening-standard-v1` 为0.29 USDC，包含10个固定维度、优先查询鲸海；仅行政许可工具 `v3_license_list` 连接/调用失败或已熔断时，才以3积分调用一次企查查 `get_administrative_license`，最多100条、不翻页、不重试。增强报告 `screening-enhanced-v1` 为0.59 USDC，另始终查询一次企查查资质（最多30条），企查查最多调用两次。许可回退保留两个来源，不声称记录完整；其他维度不回退，也不是全部64个工具兜底。其他检查失败或两家服务商均失败时不结算。单独资质产品 `qcc-qualifications-v1` 为0.03 USDC，只返回规范JSON、最多30条，不含报告分析。整份筛查报告也可用 get_china_company_report，经 MCP 转接同一 HTTP x402 结算链路；企查查资质单项仍仅支持 HTTP。另有免费套餐查询及原单恢复工具。2026-10-15，一次由所有者出资的0.29 USDC标准版MCP测试通过公开Python示例完成，15.78秒返回全部十项合同范围内容，核对为恰好一次结算，触发企查查行政许可回退，并恢复出相同JSON及中英文HTML，未新增服务商调用或付款。该报告不是完整尽调，结论仍为 `insufficient_evidence`；这是内部测试，不代表客户需求。当前增强版、韧性版合约尚无实付验收；尚无实付验收覆盖完整的64工具目录，另有记录的一次 v3_company_detail HTTP 测试不代表完整目录通过验收。交付依赖服务商余额和运行可用性；没有人工日或总商用额度限制，但仍受单笔限制且不保证交付。详见产品说明。
以下为保留的旧版 Basic/Full 套餐摘要，不代表当前 V3 的完整目录：Basic 每次 0.032 USDC，包含工商、经营异常、行政处罚；Full 每次 0.093 USDC，另含严重违法、被执行、失信、破产、资质、海关，共九个模块。旧版套餐的每个列表仅首页、最多十条；不含政府采购历史，不自动翻页或补查历史。旧域名及工具名保留；免费实体检索、原生 MPP 和旧 the402 回调暂不提供原服务。没有记录不代表没有风险。以实时 OpenAPI 和支付报价为准。
