# Bulk SSL Certificate Expiry Checker

**Use case:** 

Check SSL certificate expiry for a whole list of domains at once: one row per site with the certificate issuer, expiry date and days left (negative = already expired), plus a flag for certificates expiring within 14 days. Filter by days left or the SSL_EXPIRING_SOON issue code. Schedule it weekly in monitoring mode to get only the sites whose certificate changed or is about to expire.

## Input

```json
{
  "websites": [
    "apify.com",

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/quanta1810/website-health-audit.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
