本演练围绕一个问题展开——“此刻有哪些公司正在向英国扩张，原因是什么？“——从市场仪表盘一路深入到一家公司举措背后的单条信号。下文中的每一个请求和响应都使用真实的扩张 API 结构。
第 1 步 — 找到正在进入英国的新鲜入境行动者
设置 tos: ["GB"] 以找到所有正在进入英国的公司，再加上新鲜度筛选，这样您只会看到正在积极抵达的公司。
POST /expansions/lookup
{
"tos": ["GB"],
"freshness": ["fresh", "cooling"],
"page": 1,
"per_page": 25
}
{
"metadata": {
"filters": { "tos": ["GB"], "freshness": ["fresh", "cooling"] },
"aggregate": { "total_companies_with_signals": 64, "committing_count": 22, "expanding_count": 15 },
"top_origins": [{ "home_country_code": "CN", "company_count": 18 }],
"top_industries": [{ "industry": "Consumer Electronics", "count": 9 }]
},
"data": {
"pagination": { "page": 1, "per_page": 25, "total_entries": 64, "total_pages": 3 },
"companies": [
{
"expansion_id": "6845525",
"domain_search_id": "550e8400-e29b-41d4-a716-446655440002",
"company_name": "Example Corp",
"domain": "example.com",
"home_country_code": "CN",
"country_code": "GB",
"industry": "Consumer Electronics",
"stage": { "slug": "expanding", "expansion_score": 0.72, "scope": "entering_new_market", "direction": "advancing", "freshness": "fresh", "signal_count": 7 }
}
]
}
}
expansion_score 排序，把最果断的行动者排在最前。这里，一家位于中国的公司（home_country_code: "CN"）在 GB 处于拓展中（expanding）阶段，呈 advancing 轨迹——这是一次强劲、新鲜的入境举措。
第 2 步 — 查看该公司完整的市场地图
取出 domain_search_id，列出该公司正在进入的每一个市场。
POST /expansions/companies/lookup
{ "domain_search_id": "550e8400-e29b-41d4-a716-446655440002", "is_all_markets": true }
{
"metadata": { "domain_search_id": "550e8400-e29b-41d4-a716-446655440002", "home_country_code": "US" },
"data": { "market_count": 2, "dominant_stage_slug": "expanding", "total_signal_count": 194 },
"markets_summary": [
{ "country_code": "GB", "stage_slug": "expanding", "is_home_market": false, "signal_count": 140, "distinct_type_count": 6, "latest_signal_at": "2026-07-08T02:42:23.544Z", "rank_now": 1 },
{ "country_code": "DE", "stage_slug": "committing", "is_home_market": false, "signal_count": 54, "distinct_type_count": 3, "latest_signal_at": "2026-06-20T00:00:00.000Z", "rank_now": 2 }
]
}
第 3 步 — 深入理解其在英国的举措
深入到”公司—市场”详情，查看当前阶段、底层信号、已知存在以及阶段转换时间线。
POST /expansions/companies/lookup
{ "domain_search_id": "550e8400-e29b-41d4-a716-446655440002", "country_code": "GB" }
{
"metadata": { "domain_search_id": "550e8400-e29b-41d4-a716-446655440002", "country_code": "GB" },
"data": {
"domain_search_id": "550e8400-e29b-41d4-a716-446655440002",
"country_code": "GB",
"country_name": "United Kingdom",
"stage_rank": 3,
"stage_name": "Expanding",
"stage": { "slug": "expanding", "expansion_score": 0.72, "scope": "entering_new_market", "direction": "advancing", "freshness": "fresh", "signal_count": 27 }
},
"signals": [
{
"signal_type_slug": "EXEC",
"display_label": "Hired Regional VP for UK & Ireland",
"polarity": "expansion",
"event_date": "2026-06-20T14:00:00.000Z"
}
],
"presence": [
{ "presence_type": "office", "address": "London, UK", "known_since": "2026-03-15T00:00:00.000Z" }
]
}
第 4 步 — 读取单条事件
如需驱动该举措的完整、分页的事件列表，调用信号事件端点并指定您关注的信号类型。
POST /expansions/companies/pulse_events
{
"domain_search_id": "550e8400-e29b-41d4-a716-446655440002",
"signal_types": ["HIRE", "EXEC"],
"window_days": 90,
"page": 1
}
{
"metadata": { "domain_search_id": "550e8400-e29b-41d4-a716-446655440002" },
"data": {
"pagination": { "page": 1, "per_page": 25, "total_entries": 42, "total_pages": 2, "total_display_pages": 2, "is_timeout": false },
"events": [
{
"signal_type_slug": "EXEC",
"country_code": "GB",
"display_label": "Hired Regional VP for UK & Ireland",
"evidence_url": "https://www.linkedin.com/company/example-corp",
"event_date": "2026-06-20T14:00:00.000Z"
}
]
}
}
page 直到其达到 total_pages，来驱动”加载更多”控件。
您刚刚做了什么
您从一个市场 → 一份排序后的行动者名单 → 一家公司的完整足迹 → 其在英国扩张背后的确切信号。这就是扩张 API 的核心循环：从宽泛入手，收窄到一家公司，然后读取证据。
