GraphQL AccessALPHA

Access Unicode Escape/Unescape through GraphQL to combine it with other API calls in a single request. Query only the unicode escape/unescape data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Unicode Escape/Unescape 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 {
  unicodeescape(
    input: {
      text: "Hello World"
      action: "escape"
    }
  ) {
    action
    original
    escaped
    character_count
    unicode_points
  }
}

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

CORS Support

The Unicode Escape/Unescape 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

Unicode Escape/Unescape 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 Unicode Escape/Unescape 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 →

SDKs for Unicode Escape/Unescape

Official Unicode Escape/Unescape packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →
