64 individually priced Chinese company data tools at 0.011 USDC per call via remote MCP/x402 on Base; 68 MCP definitions total. Legacy Basic (3 modules, 0.032 USDC) and Full (9 modules, 0.093 USDC) remain separate packages. Additional HTTP x402 products, NOT new MCP tools: Standard screening 0.29 USDC (ten Jinghai checks, JSON plus Chinese/English HTML); Enhanced screening 0.59 USDC (the same ten checks plus exactly one QCC qualifications check); QCC qualifications 0.03 USDC (normalized JSON, up to 30 records, no screening analysis). Product guide: https://yangchunhong3000.github.io/cn-evidence-public-docs/products.html Discovery is free; data queries require a funded Base USDC wallet and explicit x402 spending approval. Plain MCP clients do not pay automatically. Most V3 company tools require company_id from company_detail; record details use record_id from a matching, separately paid parent list. New paged lists return at most five first-page rows; legacy lists at most ten. No automatic pagination, top-up, retry or repayment. Provider balance and service availability apply. Selected records and limited-scope screening only: empty is not no risk; statistics/trends are not detailed records. No complete due diligence, human review, factory verification or supplier-safety guarantee. Native MPP is paused. Internal owner-funded HTTP company-detail, Standard and old QCC v1 samples passed paid delivery/recovery checks. The later QCC v2 funding-policy revision has offline/isolated and unsigned checks, not a fresh funded acceptance. These tests are not customer sales or certification of every tool or MCP client.
