Headers
Required and optional headers for API requests:
| Header Name | Required | Example Value | Description |
|---|---|---|---|
| X-API-Key | Yes | your_api_key_here | Your APIVerve API key. Found in your dashboard under API Keys. |
| Accept | No | application/json | Specify response format: application/json (default), application/xml, or application/yaml |
| User-Agent | No | MyApp/1.0 | Identifies your application for analytics and debugging purposes |
| X-Request-ID | No | req_123456789 | Custom request identifier for tracking and debugging requests |
| Cache-Control | No | no-cache | Control caching behavior for the request and response |
GraphQL AccessBETA
Most APIVerve APIs support GraphQL queries, allowing you to combine multiple API calls into a single request and retrieve only the data you need. This powerful feature enables you to orchestrate complex data fetching with precise field selection.
Not all APIs support GraphQL. Check the API schema or test in the GraphQL Explorer to confirm availability for this specific endpoint.
Token Cost: GraphQL requests cost 1 token for orchestration, plus the standard token cost for each API called in your query. For example, querying 3 APIs in a single GraphQL request would cost 1 + 3 = 4 tokens total.
POST https://api.apiverve.com/v1/graphqlquery {

grid

}
solutionImage {

}
}
}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
All APIVerve APIs support Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call the API 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 make direct API calls from JavaScript running in the browser without encountering CORS errors. No additional configuration needed.
Rate Limiting
APIVerve implements rate limiting to ensure fair usage and maintain service quality across all users. Rate limits vary by subscription plan and are applied per API key.
| Plan | Rate Limit | Description |
|---|---|---|
| Free | 5 requests/min | Hard rate limit enforced - exceeding will return 429 errors |
| Starter | Smart Limiting | Production ready - performance-based throttling only as last resort |
| Pro | No Limit | Production ready - no rate limiting or throttling |
| Mega | No Limit | Production ready - no rate limiting or throttling |
Rate Limit Headers
When rate limits apply, each API 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, the API returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.
Starter Plan: Smart limiting may slow down request processing during extreme load as a last resort, but will not return errors. All paid plans (Starter, Pro, Mega) are production-ready.
Pro & Mega Plans: No rate limiting or throttling applied.
Best Practices:
- Monitor the rate limit headers to track your usage (Free plan only)
- Implement caching where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle performance
Note: Rate limits are separate from token consumption. You may have tokens remaining but still hit rate limits on Free tier.
Client Libraries
To get started with minimal code, most of our APIs are available through client libraries and clients:
Error Codes
The 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 tokens | Check token 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?
What are tokens and how do they work?
Tokens are your API usage currency. Each successful API call consumes tokens based on the API's complexity. Most APIs cost 1 token per call, while more complex APIs may cost 2-5 tokens. Failed requests and errors don't consume tokens. Check the API details above to see the token cost for this specific API.
Can I use this API in production?
The free plan is for testing and development only. For production use, 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 this API from a browser?
What happens if I exceed my token limit?
When you reach your monthly token limit, 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.
