GraphQL AccessALPHA

Access Company Lookup through GraphQL to combine it with other API calls in a single request. Query only the company lookup data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Company Lookup in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint

POST https://api.apiverve.com/v1/graphql

GraphQL Query Example

query {
  companylookup(
    input: {
      ticker: "AAPL"
    }
  ) {
    count
    companies
  }
}

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 accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Company Lookup requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Company Lookup API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →

Frequently Asked Questions

How do I get an API key for Company Lookup?

Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for Company Lookup and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.

How many credits does Company Lookup cost?

Each successful Company Lookup API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful company lookup lookups.

Can I use Company Lookup in production?

The free plan is for testing and development only. For production use of Company Lookup, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.

Can I use Company Lookup from a browser?

Yes! The Company Lookup API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.

What happens if I exceed my Company Lookup credit limit?

When you reach your monthly credit limit, Company Lookup API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.

Other ways to use Company Lookup

Set up Company Lookup on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
