China Supply Check · Agent-ready sourcing research

Find China supplier candidates with evidence you can inspect.

Start with a product photo and optional notes, or use the existing written product/model brief. A completed image check returns 1–3 distinct source-backed supplier candidates, an English report and Agent JSON. Inspect image-match evidence, price units, exclusions and unknowns before deciding.

Start with a product photo — $2.99 Prepare via an MCP client

Ask support about an order. Sending a message does not accept an order or authorize payment.

Card checkout & purchase help

Image checkout is $2.99 via Stripe after free editable confirmation; its entry checks live availability before payment. Agent purchases use 2.99 USDC on Base via x402 and signed confirmation. Opening an entry or preparing a brief does not charge or contact suppliers. Legacy text/model Stripe is OFF.

Start with a photo · China Supply Check

Take a product photo. Find suppliers worth comparing.

Upload or take one product photo and add optional notes, such as material, colour, size or quantity. Review and edit the free brief, then explicitly confirm before a $2.99 Stripe-hosted payment. The entry checks current availability; opening it does not charge you.

Start with a product photo — $2.99 Use an Agent instead

On a completed image check, receive 1–3 distinct source-backed supplier candidates, an English report and Agent JSON. Fewer qualifying suppliers means an explicit shortage, never invented alternatives. We compare the main product; photographed accessories are not promised.

Original CNY prices and approximate USD conversions retain their units and tiers. Listed prices are not supplier-confirmed quotations; taxes, freight, customs and destination charges are excluded unless confirmed. Source factory signals are not a SeekAPI independent factory audit. No supplier contact or paid RFQ is included.

Already paid? Use your saved private result and recovery controls; do not pay again to reopen the same order. Agents should read live MCP discovery before preparing or purchasing through x402.

Supplier RFQ-worthiness and exact product qualification are separate. The successful check delivers three evidence-backed supplier candidates worth advancing to RFQ; exact product specifications and requested-quantity fit are reported with their supporting evidence or remaining gaps.

What is China Supply Check?

China Supply Check screens China B2B platform-shop listings against a buyer’s product or model, quantity and hard specifications. On a successful paid check, it returns three distinct documented shop candidates with source links, observed listing-price basis, MOQ and quantity fit, specification matches, exclusions and unknowns. If three cannot be supported, it reports the shortage. Certification, company-registration and production-versus-trade identity evidence is reported per candidate when the listing or a bound source provides it; a published listing price is dated supplier commercial evidence with its currency, unit, tier and MOQ conditions, while a confirmed reply for your exact RFQ is a separate step. Free Product Brief preparation is available through an MCP-capable client. A paid order requires separate scope and payment confirmation; supplier outreach is not included in this check.

The sourcing decision

One product brief. Three shop candidates worth advancing to RFQ on success.

The fee buys a bounded, source-linked comparison: search and duplicate screening, hard-specification and MOQ checks, observed price normalization, explicit exclusions and an editable RFQ starting point. If fewer than three qualify, SeekAPI reports the shortage rather than inventing suppliers.

State what must match

Provide a text product specification or model/part number, positive quantity and unit, up to five hard attribute requirements and whether substitutions are permitted.

Screen listing evidence

Compare the named item, material or other required specifications, minimum order quantity and compatible units. Exclude hard mismatches and duplicate documented shop IDs.

Review the evidence

For each of three distinct shop candidates worth advancing to RFQ on a successful result, inspect source links and observation time, displayed price currency/unit/tier if shown, MOQ and quantity fit, matched or unknown facts, and exclusions.

Evidence limits

Read the supplier-published price with its commercial conditions.

A display price is a dated platform observation, possibly a range or tier. Its currency, per-unit or pack basis and applicable quantity can differ from your requested order. A stated MOQ is not stock or a promise to make an exception. A current supplier quotation or EXW term needs a direct reply for your exact RFQ and terms.

The reported identity is a documented B2B platform shop. Certification, company-registration, production-versus-trade identity, the available shop or listing contact path, current availability and lead time are reported per candidate when the listing or a bound source provides them; fields without such evidence are marked for that candidate, and a confirmed direct reply is distinct from an available contact.

Next action

Need a current answer? Live RFQ Compare is a separate future service.

The planned USD 19.90 Live RFQ Compare would use one RFQ that you edit and confirm, with up to three selected recipients. After separate payment and authorization, one human outreach round over a 72-hour response window would request current price, availability, MOQ and lead time. Replies are not guaranteed, and this service is not open for purchase.

How the RFQ handoff would work

Before placing an order, read the Service Terms and Privacy Notice. A free brief or support question does not accept an order.

Inspect the evidence before deciding.

The sample summary records an authorized production acceptance; the separate archived V4 example is a historical evidence-format sample preserved for provenance.
