CheckRedirects
A URL redirect inspection API we built for our own dedup and migration work. Resolve any URL, get back the full chain, with batch support up to 500 URLs and webhook callbacks. Free tier, no credit card.
Why we built this
We do a lot of deduplication and record merging on Attio projects. Matching people and companies across messy datasets means resolving redirected URLs at scale, and the existing tooling we tried was either cumbersome, expensive, or genuinely difficult to even get an API key for.
The capabilities existed in the broader ecosystem, they were just buried in UI-centric tools without proper API access, or behind signup flows that took how-to guides to get a key out of. We built CheckRedirects with the opposite priorities: API-first, programmatic by default, keys issued in seconds, and an MCP server on top so it slots into agent workflows without extra glue.
It's running in our own pipelines for client work, and it's available for anyone else who wants redirect checks at scale without fighting their tooling to get there.
Frequently Asked Questions
Is there a free tier?
Yes. The free tier covers small batches and one-off checks. Paid plans kick in when you need higher volume, or more concurrency.
How fast can I get an API key?
Seconds. Sign up at checkredirects.io, hit the dashboard, and a key is issued on the spot. No credit card required.
Can I use it from an MCP client?
Yes. CheckRedirects ships with an MCP server, so you can wire the same redirect-checking capabilities into Claude, Cursor, or any other MCP-compatible agent without writing extra glue.
