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 You can call it straight away; rate limits still apply (Unpublished).

Can I call MyMemory from the browser?

Is MyMemory up right now?

MyMemory is catalogued but not yet on our probe schedule, so we don't publish a live status for it. Check the provider's own status page or docs for its current state.
