Read the evidence and current purchase options.

The public sourcing product

China Supply Check is the supplier-screening entry. Connect to https://api.seekapi.ai/mcp and read discover_china_supply_check_v0 before preparing or purchasing. Free discovery and preparation are separate from the explicit paid purchase; supplier outreach is a later separately authorized action.

Public evidence reads

• Human supplier example
• Exact Agent sample JSON
• OpenAPI documentation for public HTTP reads
• Current public contract and dated payment observation
• Agent manifest and human handoff status

OpenAPI documents existing public read routes only. It does not invent an HTTP payment endpoint or replace the MCP purchase contract. Historical orders retain their original policy; authenticated results are read without repayment.

Other product-data tools are restricted pilot or sandbox capabilities as disclosed by their own discovery; they are not additional live sourcing products.

Product-first V2

Match the product first. Compare the evidence next.

1. Admit evidenced product matches without a known hard product conflict. Missing non-hard information stays an RFQ question.
2. Calculate the product commercial score: comparable price 45%, scoped sales 35%, MOQ fit 10%, freshness and active status 10%. Missing evidence receives zero credit.
3. Deduplicate connected legal business, marketplace member and shop identities. Several listings from the same supplier do not create extra supplier slots. Preserve the identity level and confidence actually observed.
4. Protect at most 20 unique suppliers within 10 product-score points of the best matching product.
5. Select source factory tiers F5→F0 within that protected pool; compare product score within a tier. A factory badge cannot rescue a wrong product.
6. Use Q1–Q6 as a trust profile and auxiliary explanation. These are not six all-PASS admission gates, and factory evidence is not counted twice.

The target is three actionable supplier candidates. Ordinary incomplete pools remain provisional; weak or conflicting products do not fill the count. Source-platform certification is not an independent SeekAPI onsite audit. Source protections apply only to eligible source product transactions, not compensation for the CSC fee.

The anonymous public sample uses csc.public-agent-sample.v4. No commercial recommendation is made; first display preserves recorded order. Fact coverage is NOT_RECORDED/UNKNOWN; three of three references resolving into the catalog is reference linkage only, not procurement completeness or independent audit.

The public example reconstructs preserved historical evidence. Its original pool and weights are NOT_RECORDED; current V2 scores are RECOMPUTED. Its tied 0/100 scores and F0 tiers do not establish commercial superiority or prove a supplier is not a factory.
