GraphQL AccessALPHA

Access Unicode Character Lookup through GraphQL to combine it with other API calls in a single request. Query only the unicode character lookup 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/graphql

query {
  unicodelookup(
    input: {
      character: "👋"
      codepoint: "1F44B"
    }
  ) {
    character
    codepoint
    decimal
    hex
    utf16
    category
    name
  }
}

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

CORS Support

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

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

Rate Limiting

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

Learn more about rate limiting →

Rate Limit Headers

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

Handling Rate Limits

Free Plan: When you exceed your rate limit, Unicode Character 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 Unicode Character Lookup:

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

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

Error Codes

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