Core Capabilities and Architecture

The fuzzy search endpoint provides flexible matching across multiple corporate identifiers, including entity names, 15-digit registration numbers, and 18-digit unified social credit codes. Responses deliver structured payloads containing entity category enumerations (e.g., 0 for standard enterprises, 4 for associations, 5 for law firms, 6 for Hong Kong entities), legal representatives, and founding dates. By default, the system returns the top 10 most relevant matches, though cached queries may yield up to 19 records. The billing mechanism operates on a success-based model, charging only when valid data is retrieved.

Endpoint Specification

Request Parameters

# Shell request demonstration
curl -G "https://api.corp-search.io/v1/fuzzy" \
     --data-urlencode "search_term=Chongqing Tech" \
     --data-urlencode "auth_token=YOUR_ACCESS_TOKEN"

Security Notice: The auth_token serves as a unique identifier and must be secured to prevent unauthorized usage.

Integration Patterns

Financial System Validation

# Invoice header verification logic
def verify_invoice_header(target_org_name):
    api_response = requests.get(
        "https://api.corp-search.io/v1/fuzzy",
        params={
            "search_term": target_org_name[:20],
            "auth_token": os.environ['API_TOKEN']
        }
    )
    payload = api_response.json()
    if payload.get('status') == 200:
        matched_entities = payload['results']
        return any(entity['entityName'] == target_org_name for entity in matched_entities)
    return False

Supply Chain Management

During vendor qualification audits, the API enables:

• Automated supplier name completion
• Social credit code authenticity checks
• Dynamic calculation of corporate longevity

Data Platform Caching

// Java Spring caching implementation
@Cacheable(value = "corpSearchCache", 
           key = "#searchTerm",
           unless = "#result == null || #result.getBody().getResults().isEmpty()")
public ResponseEntity<Map<String, Object>> fetchCorporateData(String searchTerm, String authToken) {
    // API invocation implementation
}

Performance and Billing Optimization

Cost Management

The transaction-based pricing model applies fees exclusively to successful data retrievals:

• Successful match: Nominal micro-fee per request
• Empty result set: No charge applied
• New accounts: Complimentary 20 daily queries

Query Optimization Strategies

• Search Term Refinement: Prefer distinct entity name fragments. Including regional prefixes (e.g., "Beijing", "Shanghai") significantly boosts match accuracy.
• Local Caching: Store high-frequency queries locally with a TTL of 300 seconds. Employ asynchronous I/O for concurrent batch processing.

Quota Monitoring

Administrators can track utilization metrics and remaining complimentary allocations through the developer dashboard metrics portal.
