GraphQL AccessALPHA

Access CSV to JSON Converter through GraphQL to combine it with other API calls in a single request. Query only the csv to json converter data you need with precise field selection, and orchestrate complex data fetching workflows.

Test CSV to JSON Converter 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 {
  csvtojson(
    input: {
      csv: "name,age,city
John Doe,30,New York
Jane Smith,25,Los Angeles"
      delimiter: ","
      has_header: true
    }
  ) {
    row_count
    column_count
    columns
    inferredTypes {
      name
      age
      city
    }
    json
  }
}

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

CORS Support

The CSV to JSON Converter API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call CSV to JSON Converter 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 CSV to JSON Converter directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

CSV to JSON Converter API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all CSV to JSON Converter 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 CSV to JSON Converter 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, CSV to JSON Converter 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 CSV to JSON Converter:

  • Monitor the rate limit headers to track your CSV to JSON Converter usage (Free plan only)
  • Cache csv to json converter responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle CSV to JSON Converter performance

Note: CSV to JSON Converter rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using CSV to JSON Converter on Free tier.

Error Codes

The CSV to JSON Converter 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
