24Symbols

24Symbols is a digital reading subscription service, often described as a "Spotify for books," giving readers unlimited access to a catalog of more than 500,000 e-books across Spanish, English, German, Italian, Portuguese, and French for a flat monthly fee. Founded in Madrid and backed by Seedcamp, the platform lets subscribers read on smartphones, tablets, e-readers, and the web, build personal bookshelves, track reading progress, and follow other readers and authors through its social reading community. Alongside its consumer premium plan, 24Symbols offers B2B "reading space" solutions that let hotels, telecoms, media outlets, educational institutions, and loyalty or employee programs license library access for their audiences. The company operates as a consumer- and business-facing subscription product and does not currently publish a public developer API, SDK, or partner integration surface; this profile captures its verifiable identity and public web properties.

24Symbols is profiled on the APIs.io network. Tagged areas include Company, Books, E-books, Reading, and Digital Library.

24Symbols’ developer surface includes support, pricing, signup flow, engineering blog, and 5 more developer resources.
