LectServe vs Nager.Date

LectServe is a one-person hobby project publishing the daily and Sunday Revised Common/ACNA lectionary readings for Protestant and Anglican churches, with morning/evening prayer citations linked out to Bible Gateway. It answers in either shape depending on the path: /today and /date/YYYY-MM-DD return JSON, while a path like /html/daily/YYYY-MM-DD returns a full HTML page meant to be embedded or scraped — and there's no API key, rate limit, or pricing of any kind — it's maintained by its author, Michael Wayne Arnold, as a labor of love alongside his personal site.

Nager.Date is a free, open-source public holiday API covering 204 countries, with endpoints for a year's full holiday list, the next public holiday, whether today is a holiday, and country metadata — all keyless JSON with no rate limiting. It's maintained on GitHub by a single developer and is popular as the default holiday backend baked into several scheduling and HR libraries specifically because it needs no signup. The old v3 endpoints are deprecated; the provider will retire them on 31 January 2027, so new integrations should use v4.
