风控与反欺诈

欺诈评分、制裁（OFAC）筛查、设备 / IP 指纹与实名认证（KYC），统一在一个风控 API 后面。

1. 概览

基础路径: https://api.infrai.cc/v1/risk

鉴权头: Authorization: Bearer $INFRAI_API_KEY

bash

# Call any /v1/risk capability over raw HTTP — no SDK to install.
# curl:
curl https://api.infrai.cc/v1/risk/... \
  -H "Authorization: Bearer $INFRAI_API_KEY" \
  -H "Content-Type: application/json"

2. 方法 (3)

2.1risk.score

POST /v1/risk/score

对用户 / 账户事件（登录、支付、注册）进行欺诈与滥用风险评分，返回 0..1 归一化分数及接受 / 复核 / 拒绝处置。计费工作动作，ML 高毛利（service_markup）。

高级:指定 vendor

默认情况下 infrai 会把每次调用智能路由到最佳可用供应商——无需自己挑选 vendor。作为高级逃生口,本能力支持可选的 vendor 入参以锁定某个供应商。本能力当前所有可用 vendor 可通过该能力 id 对应的 discovery 端点实时获取——参见 discovery API。

GET /v1/discovery/{capability}
