CORS Support
The HTML to PDF 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
HTML to PDF 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 HTML to PDF 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 HTML to PDF
Official HTML to PDF packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →
No-Code Integrations
HTML to PDF works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →
