Stock Index API
Stock Index is a tool for retrieving current and historical stock market index values. It supports the S&P 500, Dow Jones, Nasdaq Composite, VIX, Nikkei 225, and more.
The Stock Index API provides reliable and fast access to stock index data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.
To use Stock Index, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA
Access Stock Index through GraphQL to combine it with other API calls in a single request. Query only the stock index data you need with precise field selection, and orchestrate complex data fetching workflows.
Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.
POST https://api.apiverve.com/v1/graphqlquery {
stockindex(
input: {
index: "sp500"
year: 2023
month: 6
}
) {
index
name
year
month
count
entries
}
}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
The Stock Index API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Stock Index directly from browser-based applications without proxy servers.
| CORS Header | Value | Description |
|---|---|---|
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 Stock Index directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.
Rate Limiting
Stock Index API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Stock Index users.
| Plan | Rate Limit | Description |
|---|---|---|
| Free | 5 requests/min | Hard rate limit enforced - exceeding will return 429 errors |
| Starter | No Limit | Production ready - standard traffic priority |
| Pro | No Limit | Production ready - preferred traffic priority |
| Mega | No Limit | Production ready - highest traffic priority |

Rate Limit Headers
When rate limits apply, each Stock Index response includes headers to help you track your usage:
| Header | Description |
|---|---|
X-RateLimit-Limit | Maximum number of requests allowed per time window |
X-RateLimit-Remaining | Number of requests remaining in the current window |
X-RateLimit-Reset | Unix timestamp when the rate limit window resets |
Handling Rate Limits
Free Plan: When you exceed your rate limit, Stock Index 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 Stock Index:
- Monitor the rate limit headers to track your Stock Index usage (Free plan only)
- Cache stock index responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Stock Index performance
Note: Stock Index rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Stock Index on Free tier.
Error Codes
The Stock Index API uses standard HTTP status codes to indicate success or failure:
| Code | Message | Description | Solution |
|---|---|---|---|
200 | OK | Request successful, data returned | No action needed - request was successful |
400 | Bad Request | Invalid request parameters or malformed request | Check required parameters and ensure values match expected formats |
401 | Unauthorized | Missing or invalid API key | Include x-api-key header with valid API key from dashboard |
403 | Forbidden | API key lacks permission or insufficient credits | Check credit balance in dashboard or upgrade plan |
429 | Too Many Requests | Rate limit exceeded (Free: 5 req/min) | Implement request throttling or upgrade to paid plan |
500 | Internal Server Error | Server error occurred | Retry request after a few seconds, contact support if persists |
503 | Service Unavailable | API temporarily unavailable | Wait and retry, check status page for maintenance updates |

Frequently Asked Questions
How do I get an API key for Stock Index?
How many credits does Stock Index cost?
Each successful Stock Index 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 stock index lookups.
Can I use Stock Index in production?
The free plan is for testing and development only. For production use of Stock Index, 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 Stock Index from a browser?
What happens if I exceed my Stock Index credit limit?
When you reach your monthly credit limit, Stock Index 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.
