## Search

- `GET https://852db.com/api/search?q=<query>&limit=<1-50>` — JSON. Query matches company name,
  phone number, district/address, trade keyword and (for discovery) email domain text. Response
  fields: `id`, `name`, `phone[]`, `fax[]`, `website|null`, `address|null`,
  `hours|null`, `categories[]`, `has_branches`, `detail_url`. The response carries no email
  field by policy — see detail_url; rate-limited (60 req/min/IP, HTTP 429 beyond).
- Human-facing search: https://852db.com/search?q=<query>
- Every company has a stable page: https://852db.com/company/<id>

## Coverage

- 437,310 companies have a phone number; 87,017 have a published email.
- Emails are shown on each company's detail page for human visitors only; the search API does not
  return them (bulk-collection guard). Phone is the reliable machine-readable contact channel.
