## What we offer

### 1. B2B Buyer Intelligence API
Self-hosted lead generation toolkit. Customers upload their product info, the system distills targeted keywords, and downloads a Python scraping script. Data sovereignty belongs to the customer.

### 2. Public Buyer Intelligence Pool (实时滚动)
A live, anonymized feed of global procurement requests posted through Golddigger. Each entry includes company name, product needed, extracted keywords, request count, and last-seen timestamp. Contact info is stripped before publication.

Endpoint: `GET https://golddigger.gold/api/public/suppliers` — returns JSON `{total, suppliers:[{company, request_count, last_item_name, keywords, last_seen_at}]}`

Endpoint: `POST https://golddigger.gold/api/buyer/requests` — accepts `{company, contact, contact_info, quantity, delivery, certifications, samples_refs}` and returns `{status, supplier_id, request_id, keywords_extracted}`.

### 3. Graph Search
Interactive supplier-discovery interface for browsing the demand pool by geography, industry, and procurement stage. Available at `/graph_search/`.
