Render API | Encited Docs

GET/api/prerender/render

Render a JavaScript page into static HTML. Returns rendered HTML (200) or a passthrough instruction (304 + Location) when prerendering does not apply.

Query Parameters

Parameter	Type	Description
`url`required	string	URL-encoded target page to render. Must be a valid URL.

Response Headers

Header	Values	Description
`x-lovablehtml-render-cache`	`edge-hit` \| `hit` \| `miss`	Which cache tier served the response (see below)
`x-lovablehtml-snapshot-key`	string	Identifier for the stored HTML snapshot (present on `hit`)
`cache-control`	`public, max-age=N, s-maxage=N`	Cache TTL based on your domain's configured refresh interval
`etag`	`W/"sha256"`	Weak etag derived from the HTML content hash

Cache tiers

edge-hit — served from a short-lived edge tier close to the requester. Lowest latency. May serve stale content for up to 5 minutes after an invalidation.
hit — served from the durable snapshot cache. Reflects the latest successful render for your domain's refresh interval.
miss — no cache entry was usable; the page was rendered on demand.

Response Body

On 200, returns the fully-rendered HTML string with Content-Type: text/html; charset=utf-8.

On 304, the body is empty. Follow the Location header to the origin URL.

Response Codes

200

Success — Returns rendered HTML with Content-Type: text/html

304

Passthrough — Static asset, non-HTML request, or real browser navigation. Location header contains origin URL.

401

Unauthorized — Missing or invalid API key.

402

Subscription required — Rendering via API requires an active plan.

403

Forbidden — domain_not_owned or api_key_domain_scope_mismatch.

Example

javascript

CopyDownload

const response = await fetch(
  'https://encited.com/api/prerender/render?url=' +
  encodeURIComponent('https://your-app.com/page'),
  {
    headers: {
      'x-lovablehtml-api-key': '<API_KEY>',
      'Accept': 'text/html'
    }
  }
);

const html = await response.text();

// Check response headers
const cacheStatus = response.headers.get('x-lovablehtml-render-cache');
// → "edge-hit" or "hit" (cached) or "miss" (fresh render)

const snapshotKey = response.headers.get('x-lovablehtml-snapshot-key');
// Useful for debugging: the stored HTML object key (when available)

bash

CopyDownload

curl -X GET \
  "https://encited.com/api/prerender/render?url=https%3A%2F%2Fyour-app.com%2Fpage" \
  -H "x-lovablehtml-api-key: <API_KEY>" \
  -H "Accept: text/html"

python

CopyDownload

import requests
import urllib.parse

url = urllib.parse.quote('https://your-app.com/page', safe='')
response = requests.get(
    f'https://encited.com/api/prerender/render?url={url}',
    headers={
        'x-lovablehtml-api-key': '<API_KEY>',
        'Accept': 'text/html'
    }
)

html = response.text
cache_status = response.headers.get('x-lovablehtml-render-cache')

Tip: Static assets (CSS, JS, images, fonts) are never prerendered. Follow the Location header or fetch directly from origin.
