# FILTER\_INFOS API Documentation

## 🌐 Language Switch

[中文版](/docs/filter_infos.zh) | [English](/docs/filter_infos)

## Interface Information

```
POST /openapi/capcut-mate/v1/filter_infos
```

## Function Description

Generate filter information based on filter names, timelines, and intensities. This interface converts filter names and timeline configurations into the filter information format required by Jianying drafts.

## Request Parameters

```json
{
  "filters": ["复古", "黑白"],
  "timelines": [
    {"start": 0, "end": 3000000},
    {"start": 3000000, "end": 6000000}
  ],
  "intensities": [80, 100]
}
```

### Parameter Description

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| filters | array\[string] |✅ | - | Filter name array |
| timelines | array\[object] |✅ | - | Timeline configuration array |
| intensities | array\[number] | ❌ | None | Filter intensity array (0-100), optional, defaults to 100 for all |

## Response Format

### Success Response (200)

```json
{
  "code": 0,
  "message": "success",
  "infos": "[{\"filter_title\":\"复古\",\"start\":0,\"end\":3000000,\"intensity\":80},{\"filter_title\":\"黑白\",\"start\":3000000,\"end\":6000000,\"intensity\":100}]"
}
```

### Response Field Description

| Field | Type | Description |
|-------|------|-------------|
| infos | string | Filter information JSON string |

### Error Response

```json
{
  "code": 1001,
  "message": "Parameter validation failed"
}
```

## Usage Examples

### cURL Examples

#### 1. Basic Filter Information Generation

```bash
curl -X POST https://capcut-mate.jcaigc.cn/openapi/capcut-mate/v1/filter_infos \
  -H "Content-Type: application/json" \
  -d '{
    "filters": ["复古"],
    "timelines": [{"start": 0, "end": 5000000}]
  }'
```

#### 2. Filter Information with Custom Intensity

```bash
curl -X POST https://capcut-mate.jcaigc.cn/openapi/capcut-mate/v1/filter_infos \
  -H "Content-Type: application/json" \
  -d '{
    "filters": ["黑白"],
    "timelines": [{"start": 0, "end": 5000000}],
    "intensities": [60]
  }'
```

#### 3. Multiple Filter Information Generation

```bash
curl -X POST https://capcut-mate.jcaigc.cn/openapi/capcut-mate/v1/filter_infos \
  -H "Content-Type: application/json" \
  -d '{
    "filters": ["复古", "黑白", "电影感"],
    "timelines": [{"start": 0, "end": 2000000}, {"start": 2000000, "end": 4000000}, {"start": 4000000, "end": 6000000}],
    "intensities": [80, 100, 90]
  }'
```

## Error Code Description

| Error Code | Error Message | Description | Solution |
|------------|---------------|-------------|----------|
| 1001 | Parameter validation failed | Request body failed schema validation (`filters`/`timelines` missing, timeline item lacking `start`/`end`, or wrong types) | Check parameter types and required fields |

## Notes

1. **Array Matching**: `filters`, `timelines` and `intensities` are aligned by the shortest length when their lengths differ (no hard error)
2. **Time Unit**: All time parameters use microseconds (1 second = 1,000,000 microseconds)
3. **Filter Names**: Need to use system-supported filter names
4. **Intensity Range**: Intensity values are clamped to 0-100, default is 100
5. **Continuity**: Filters are applied in timeline order

## Workflow

1. Validate required parameters (filters, timelines)
2. Align the arrays by the shorter length
3. Validate timeline parameter validity
4. Clamp intensity values to the 0-100 range (if provided)
5. Generate corresponding filter information for each filter name
6. Convert information to JSON string format
7. Return processing result
