Open Data API
Read published Longkou industry chains, product categories, products and company directory entries through versioned JSON endpoints. Public records retain their source and update-time semantics.
Access and quotas
Anonymous calls are rate-limited by source address. An API key provides a higher quota. Keys are shown once when created and can be revoked at any time.
curl "http://localhost:4321/api/v1/companies?locale=en&limit=20&offset=0"Pagination: locale (12 languages), limit (1–100; default 50), and offset (starts at 0). Pass API keys in the Authorization: Bearer lks_… header.
Public field boundary
Only published chains, categories, products, company names, public website/introduction, regions, directory relationships, public sources, update times, and separate identity/supply review statuses are returned.
Personal contacts, buyer requests, service orders, claim evidence, internal notes, drafts, admin logs and private attachments are excluded. A traceable source does not mean identity or supply capability is verified.

}Use and attribution
API terms still require operator and legal review. These endpoints expose public directory data only; they exclude personal contact details, buyer leads, claim evidence and internal records.
Follow source-site and data-provider terms, and retain company/product source links when citing. Do not present public relationships as platform verification or supply commitments.
