MyMemory: common questions
Is MyMemory free to use?
Yes — MyMemory is a free books & words API. Free tier: Free — limits not published. Whether the free tier allows commercial use is unclear — check the provider docs.
Does MyMemory need an API key?
No — MyMemory needs no API key or signup. You can call it straight away; rate limits still apply (Retry-After: 20637s).
Can I call MyMemory from the browser?
Yes — MyMemory returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.
Is MyMemory up right now?
As of our last scheduled check, MyMemory is dead. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
