BuyWhere for Enterprise: Multi-Region Catalog, SLAs, and Integration Patterns

By Draft · April 2026

Evaluating a new API for production use requires understanding latency, reliability, and security guarantees. This post covers the key considerations for enterprise integration.

Multi-Region Catalog

BuyWhere maintains product data across multiple Southeast Asian markets:

Data Freshness

• Real-time price/availability from direct API integrations
• Scraped data refreshed every 6-24 hours depending on retailer
• Historical price tracking available via PriceHistory endpoint

Latency Benchmarks

Note: The following are placeholder benchmarks. Production values will be provided upon request with your account team.

Factors affecting latency:

• Number of retailers being queried
• Cache hit rate (typically 80%+ for repeated queries)
• Geographic distance to API region

Rate Limit Policy

Rate limit headers returned on every response:

X-RateLimit-Limit: 1000
X-RateLimit-Remaining: 847
X-RateLimit-Reset: 1713246000

Failover Pattern

For production reliability, implement exponential backoff with jitter:

import random
import time
import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

def create_session_with_retries(max_retries=3):
    session = requests.Session()
    
    retry_strategy = Retry(
        total=max_retries,
        backoff_factor=1,
        status_forcelist=[429, 500, 502, 503, 504],
    )
    
    adapter = HTTPAdapter(max_retries=retry_strategy)
    session.mount("https://", adapter)
    session.mount("http://", adapter)
    return session

# Usage
session = create_session_with_retries()
response = session.get(
    "https://api.buywhere.ai/v1/agents/search",
    headers={"Authorization": f"Bearer {API_KEY}"},
    params={"q": "laptop"},
    timeout=30
)

Circuit Breaker Pattern

For high-volume production use, implement a circuit breaker:

from functools import wraps

class CircuitBreaker:
    def __init__(self, failure_threshold=5, timeout=60):
        self.failure_threshold = failure_threshold
        self.timeout = timeout
        self.failures = 0
        self.last_failure_time = None
        self.state = "closed"  # closed, open, half-open
    
    def call(self, func, *args, **kwargs):
        if self.state == "open":
            if time.time() - self.last_failure_time > self.timeout:
                self.state = "half-open"
            else:
                raise Exception("Circuit breaker is open")
        
        try:
            result = func(*args, **kwargs)
            if self.state == "half-open":
                self.state = "closed"
                self.failures = 0
            return result
        except Exception as e:
            self.failures += 1
            self.last_failure_time = time.time()
            if self.failures >= self.failure_threshold:
                self.state = "open"
            raise e

Authentication Security

API Key Authentication

All API requests require Bearer token authentication:

curl -H "Authorization: Bearer your_api_key_here" \
  "https://api.buywhere.ai/v1/agents/search?q=laptop"

Key Rotation

• Keys can be rotated without downtime via the dashboard
• Set rotated_from_key_id to maintain audit trail
• Old keys remain valid for a 24-hour grace period after rotation

Security Best Practices

1. Store keys securely — Use environment variables or a secrets manager
2. Restrict by origin — Configure allowed IP/CORS origins in the dashboard
3. Monitor usage — Set up alerts for anomalous request volumes
4. Use key scopes — Restrict keys to specific endpoints if full access isn't needed

Integration Checklist

• Obtain API credentials from buywhere.ai/api-keys
• Configure allowed origins for CORS
• Implement retry logic with exponential backoff
• Set up monitoring for rate limit headers
• Test failover by temporarily blocking API endpoints
• Review API documentation for endpoint-specific details

Get Started

• API Keys — Get production credentials
• Integrate — See all supported retailers and data fields
• Documentation — Full API reference and guides
