Legacy Response Format

When using legacy=true, the response follows a simplified format for backward compatibility:

{
  "status": "success",
  "result": {
    "month": "202501",
    "tenant_id": "tenant123",
    "total_requests": 4500,
    "total_errors": 150,
    "total_matches": 600,
    "avg_processing_ms": 0,
    "by_list": {}
  }
}

The legacy format only returns current month data and a simplified metric set. For detailed metrics and historical data, use the standard response format.

Usage Examples

Python Example

import requests
from datetime import datetime

token = "YOUR_TOKEN"
base_url = "https://stg.kyc.legaltalent.ai/kyc/usage"

# Get daily metrics for current month
response = requests.get(
    f"{base_url}?granularity=day",
    headers={"Authorization": f"Bearer {token}"}
)

if response.status_code == 200:
    data = response.json()
    print(f"Total checks this month: {data['summary']['check_count']}")
    
    # Plot daily trends
    for day in data['data']:
        print(f"{day['timestamp']}: {day['metrics']['check_count']} checks")

JavaScript Example

const token = "YOUR_TOKEN";

async function getUsageMetrics() {
  const response = await fetch(
    "https://stg.kyc.legaltalent.ai/kyc/usage?granularity=day",
    {
      headers: {
        "Authorization": `Bearer ${token}`
      }
    }
  );
  
  const data = await response.json();
  
  if (response.ok) {
    // Display summary
    console.log(`Total checks: ${data.summary.check_count}`);
    
    // Chart data points
    const chartData = data.data.map(point => ({
      date: point.timestamp,
      checks: point.metrics.check_count,
      errors: point.metrics.error_count
    }));
    
    // Use with charting library (Chart.js, D3, etc.)
    return chartData;
  } else {
    console.error("Error:", data.error);
  }
}

Error Responses

400 Bad Request - Invalid Parameters

{
  "error": "Invalid date format. Expected YYYY-MM-DD"
}

Common validation errors:

Invalid date format
Future dates/months
Invalid granularity value
Missing required date parameter for hour granularity
months out of range (must be 1-12)

403 Forbidden - Missing Permission

{
  "error": "Permission denied: usage:read required"
}

403 Forbidden - Missing Tenant

{
  "error": "Unauthorized: missing tenant_id"
}

Status Codes

Code	Description
200	Success
400	Bad Request - Invalid parameters
401	Unauthorized - Missing or invalid token
403	Forbidden - Insufficient permissions
500	Internal Server Error

Caching

Responses are cached for 5 minutes
Use cache_bust=true to force fresh data
Cache headers: Cache-Control: max-age=300
With cache_bust: Cache-Control: no-cache, no-store

Data Characteristics

Gap Filling: All periods (even with zero activity) are included for continuous charts
Immutability: Historical data never changes, so responses are cacheable
Real-time: Current day/hour data updates as requests are processed
Retention: Metrics are retained for at least 12 months

Frontend Integration Tips

The response structure is optimized for graph visualization:

// Daily granularity - 30 data points
{
  data: [
    { timestamp: "2024-10-01", metrics: {...} },
    { timestamp: "2024-10-02", metrics: {...} },
    // ... continuous, no gaps
  ]
}

// Use with any charting library
const labels = data.data.map(d => d.timestamp);
const checks = data.data.map(d => d.metrics.check_count);
const errors = data.data.map(d => d.metrics.error_count);
