可用调用方式

• EchoScanLiteClient(api_key=...)
• EchoScanProClient(api_key=...)

方法：

• Lite: get_report(imprint)
• Pro: get_report(imprint), get_history(imprint, days=..., from_=..., to=..., recent=...)

History 查询：

仅 Pro 客户端可用（需要 Pro API Key）。

返回值与错误

get_report() 顶层结构：

{
  "analysis": {},
  "lyingCount": 0,
  "projection": {}
}

get_history() 顶层结构：

{
  "imprint": "fp_session_...",
  "range": {},
  "recent": [],
  "summary": {},
  "timeline": []
}

Geo 字段说明（重要）

• SDK 只透传服务端返回，不在客户端自行做 IP 地理定位。
• 若服务端仅有 GeoLite2-Country.mmdb，通常只能返回国家级 geo；region/city 可能为空。
• 若服务端 geo enrichment 不可用，返回会降级（例如仅有 country_hint 或无 geo 字段）。
• 若服务端 geo enrichment 可用，主要查看 projection.geo.data.geo_public，字段包括：country_code、country_name、region_code、region_name、city、timezone。
• analysis.geo 提供主地理结果聚合字段：final_ip、country_code、country_name、region_code、region_name、city。
• projection.geo.data 还会带 confidence 与 geo_low_trust（例如 locale 与 IP 国家冲突）用于前端展示可信度提示。
• 在存储/调试字段中：geo_source_ip 是主判定 IP（canonical/best-effort），geo_request_client_ip 是请求链路观测 IP（证据）；两者可能不同（代理或多跳网络常见）。
• confidence 与 geo_low_trust 评价的是主结果（geo_public + geo_source_ip），不是 geo_request_client_ip 的评分。
• 若你的产品对外展示 MaxMind GeoLite 数据，请附署名：This product includes GeoLite Data created by MaxMind, available from https://www.maxmind.com.

示例

import os
from echoscan import EchoScanProClient

pro = EchoScanProClient(api_key=os.environ["ECHOSCAN_PRO_KEY"])
report = pro.get_report("fp_session_123")
history = pro.get_history("fp_session_123", from_="2026-03-01", to="2026-03-18", recent=20)

print(report)
print(history)

Usage

• EchoScanLiteClient(api_key=...)
• EchoScanProClient(api_key=...)

Methods:

• Lite: get_report(imprint)
• Pro: get_report(imprint), get_history(imprint, days=..., from_=..., to=..., recent=...)

History query:

Pro-only (requires a Pro API key).

Response and errors

get_report() top-level shape:

{
  "analysis": {},
  "lyingCount": 0,
  "projection": {}
}

get_history() top-level shape:

{
  "imprint": "fp_session_...",
  "range": {},
  "recent": [],
  "summary": {},
  "timeline": []
}

Geo fields (important)

• The SDK forwards server responses and does not perform client-side IP geolocation.
• If the backend only has GeoLite2-Country.mmdb, geo is typically country-level only; region/city may be empty.
• If backend geo enrichment is unavailable, responses degrade (for example country_hint only, or no geo fields).
• When geo enrichment is available, the primary display payload is projection.geo.data.geo_public with fields: country_code, country_name, region_code, region_name, city, timezone.
• analysis.geo provides a flattened primary result: final_ip, country_code, country_name, region_code, region_name, city.
• projection.geo.data also includes confidence and geo_low_trust (for example locale vs IP-country mismatch) for trust-aware UX.
• In storage/debug fields, geo_source_ip is the primary canonical (best-effort) lookup IP, while geo_request_client_ip is request-chain observed evidence; they may differ (common with proxies or multi-hop networks).
• confidence and geo_low_trust rate the primary result (geo_public derived from geo_source_ip), not geo_request_client_ip.
