## 数据采集
|
||
|
||
### `POST /api/v1/ingest/bzzoiro`
|
||
|
||
从 bzzoiro 采集赛果/赛程并入库(幂等,重复跑安全)。

||
|
||

|
||
{"leagues": ["E0", "SP1"], "date_from": "2025-08-01", "date_to": "2026-09-08", "status": "finished"}
|
||
```
|
||
|
||
- `status` 还可传 `scheduled` 拉未来赛程
|
||
- 响应含每联赛 `inserted`/`updated`/`errors` 统计
|
||
|
||
### `POST /api/v1/ingest/understat`
|
||
|
||
回填 xG(只补空字段,不创建比赛):
|
||
|
||
```json
|
||
{"league": "E0", "season": 2025}
|
||
```
|
||
|
||
`season=2025` 表示 2025-2026 赛季。仅支持五大联赛。
|
||
|
||
### `POST /api/v1/ingest/injuries`
|
||
|
||
采集伤停(需 `API_FOOTBALL_KEY`,当前只返回计数,尚未接入 context):
|
||
|
||
```json
|
||
{"date": "2026-09-10"}
|
||
```
|
||

|
||
|
||
## 评估
|
||
|
||
### `POST /api/v1/eval/settle`
|
||
|
||
赛后回填实际比分:
|
||
|
||
```json
|
||
{"prediction_id": 7, "home_goals": 2, "away_goals": 1}
|
||
```
|
||
|
||
### `GET /api/v1/eval/summary`
|
||
|
||
按 `provider × model` 聚合已结算预测:
|
||
|
||
```json
|
||
{"summary": [
|
||
{"provider": "openai", "model": "gpt-4o", "total": 12,
|
||
"accuracy_1x2": 58.3, "avg_score_rmse": 1.21, "avg_confidence": 0.65}
|
||
]}
|
||
```
|
||
|
||
> 提示:multi 模式存的 `model` 是终裁模型、`prompt_version` 是 `multi_v1`,
|
||
> 因此 summary 里天然可对比 multi vs single、以及不同 prompt 版本的效果。
