Merriam-Webster — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Merriam-Webster free to use?
Merriam-Webster is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Merriam-Webster need an API key?
Yes. Merriam-Webster authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call Merriam-Webster from browser JavaScript?
Not directly. Merriam-Webster did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Merriam-Webster still working?
Yes, as of 2026-09-18. Our automated check reached Merriam-Webster and recorded a 100% reliability score with a median response time of 1249 ms. We re-check on a schedule, and this page updates with the result.
Is Merriam-Webster available over HTTPS?
Yes. Merriam-Webster serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
