API Documentation Guide
Welcome
This guide provides information about using our Company Data API. For detailed endpoint specifications, schemas, and examples, please refer to the API Reference section.
What You Can Do
Our API provides access to:
- Company information and data
- Financial metrics and reports
- Industry classifications
- Historical data and trends
API Reference
All endpoint details, including:
- Request/response formats
- Parameters and schemas
- Example requests and responses
- Error codes and handling
...are available in the interactive API Reference documentation.
Authentication
API Keys
All requests require authentication using an API key. To obtain access:
- Contact your administrator for API credentials
- Include your API key in all requests
- Keep your credentials secure and never share them publicly
Using Your API Key
Include your API key in the authorization header of each request. See the API Reference for specific implementation details.
Rate Limits
To ensure service quality and availability:
- Rate limits apply to all endpoints
- Limits vary based on your subscription tier
- Exceeding limits results in temporary request throttling
Monitor your usage to stay within your allocated limits.
Response Format
All API responses are returned in JSON format with standard HTTP status codes:
| Status Code | Meaning |
|---|---|
| 2xx | Success |
| 4xx | Client error |
| 5xx | Server error |
Error Handling
When errors occur, the API returns appropriate HTTP status codes along with error details in the response body. Always implement proper error handling in your application.
Best Practices
Security
- Never expose API keys in client-side code
- Store credentials securely using environment variables
- Rotate keys periodically for enhanced security
Performance
- Cache responses when appropriate to reduce API calls
- Implement exponential backoff for rate limit handling
- Use appropriate timeouts for API requests
Reliability
- Handle network errors gracefully
- Implement retry logic for transient failures
- Monitor API health and status
