â”” unicode | string | Unicode escape sequence representation of the character | |
â”” codepoint | string | Unicode codepoint notation (e.g., U+0048) for the character |
Headers
Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →
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.
Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.
POST https://api.apiverve.com/v1/graphqlquery {
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 →
No-Code Integrations
Unicode Escape/Unescape works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →
Frequently Asked Questions
How do I get an API key for Unicode Escape/Unescape?
How many credits does Unicode Escape/Unescape cost?

Can I use Unicode Escape/Unescape from a browser?
What happens if I exceed my Unicode Escape/Unescape credit limit?
When you reach your monthly credit limit, Unicode Escape/Unescape 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.
