Integrations

Put link checking where your work already happens

Results can land in Slack, hit your own endpoint, or be pulled straight from the API. AI assistants can run checks on your behalf. Nothing here needs a plugin or an install.

Get told when something breaks

Set a URL list on a schedule and we only contact you when the result actually changes. No daily all-clear emails.

Slack

Agency plan

Post to a Slack channel when a scheduled check finds new failures. You choose whether recoveries get posted too, so the channel stays quiet until it matters.

Set up monitoring →

We POST a signed event to your endpoint when a job finishes. Signatures are HMAC-SHA256 in a Stripe-compatible header, and failed deliveries retry with exponential backoff for about 38 hours. Both SDKs ship a verify helper.

Webhook docs →

Email

Every plan, including free

The default. Submit a job, close the tab, and get an email when the report is ready. Scheduled checks email you only on a change.

How monitoring works →

Let an AI assistant do it

A hosted Model Context Protocol server, so an assistant can check URLs for you inside a normal conversation.

Claude, ChatGPT and Cursor

mcp.bulkurlchecker.com/mcp

Connect it once and ask your assistant to check a list of URLs, pull results, or look up your remaining credits. Sign in happens in the browser with OAuth, so there is no API key to paste or store.

MCP setup →

Build it into your own stack

Same engine behind every surface, including the proxy rotation and soft-404 detection.

REST API

api.bulkurlchecker.com

Submit up to 100,000 URLs in one job, poll for status, and page through results. Bearer-token auth, idempotency keys so retries are safe, and cursor pagination for clean full exports.

API reference →

Python SDK

pip install bulkurlchecker

Type hinted, MIT licensed, with an optional command line tool and a helper for verifying inbound webhook signatures.

Copy-paste recipes →

Node.js SDK

npm install bulkurlchecker

Strict TypeScript, ESM and CommonJS builds, Node 18 and up, with the same webhook signature helper.

What we do not have yet

There is no Zapier, Make or n8n connector today, and no Google Sheets add-on. If you want a check to start automatically when something happens somewhere else, the REST API is currently the way to do it.

We would rather say that plainly than let you find out after signing up. If one of those would make the difference for you, tell us which one. That is genuinely how we decide what to build next.
