Productivity currently groups 65 free APIs on saxi.ai, with strong coverage across Scheduling, Memory & Storage, and Embeddings.
Productivity APIs in this directory map the broader domain down to concrete developer surfaces. Within this section, the strongest clusters come from Documents & Productivity, Calendar, and Books, which makes the page useful both for quick browsing and for comparing adjacent tools in the same market.
For builders, this section is most useful when you know the broad problem space but not yet the exact vendor or protocol. 26 require no auth, 34 use API keys, 5 use OAuth, and 0 expose OpenAPI or Swagger metadata.
Start with high-signal entries such as Nager.Date, Non-working Days, and Open Library and then narrow further using the static topic and capability pages. This page is meant to act as the canonical landing page for productivity APIs rather than as a faceted search result.
