Company Lookup is a tool for retrieving metadata about SEC-registered public companies. Look up companies by ticker symbol, CIK number, company name, or SIC industry code. Returns company details including exchange, address, phone, and more.

The Company Lookup API provides reliable and fast access to company lookup data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.

To use Company Lookup, you need an API key. You can get one by creating a free account and visiting your dashboard.

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Company Lookup API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Company Lookup directly from browser-based applications without proxy servers.

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

Browser Usage: You can call Company Lookup directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Company Lookup API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Company Lookup users.

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Company Lookup response includes headers to help you track your usage:

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, Company Lookup returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Company Lookup:

  • Monitor the rate limit headers to track your Company Lookup usage (Free plan only)
  • Cache company lookup responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle Company Lookup performance

Note: Company Lookup rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Company Lookup on Free tier.

Error Codes

The Company Lookup API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
403ForbiddenAPI key lacks permission or insufficient creditsCheck credit balance in dashboard or upgrade plan
429Too Many RequestsRate limit exceeded (Free: 5 req/min)Implement request throttling or upgrade to paid plan
500Internal Server ErrorServer error occurredRetry request after a few seconds, contact support if persists
