  95. 97datetime.openverbs.com/v1/betweenCompute the calendar breakdown (years, months, days, hours, minutes, seconds) between two ISO 8601 dates/date-times, plus exact totalSeconds. If end precedes start the result is flagged negative rather than erroring.$0.002 Base46 ms1 payers100% up
  96. 97datetime.openverbs.com/v1/addAdd an ISO 8601 duration to a start date or date-time and return the resulting UTC instant. Calendar-aware: months and years honor month lengths (e.g. Jan 31 + P1M clamps to the last day of February). A negative-signed duration subtracts.$0.002 Base52 ms1 payers100% up
  97. 97datetime.openverbs.com/v1/humanizeRender an ISO 8601 duration as an English phrase, e.g. 'P1Y2M' → '1 year and 2 months'. Components are shown in descending order with correct pluralization.$0.002 Base159 ms1 payers100% up
  98. 97datetime.openverbs.com/v1/formatAssemble an ISO 8601 duration string from individual components (years, months, weeks, days, hours, minutes, seconds) and an optional sign. All components must be non-negative and at least one must be non-zero.$0.002 Base144 ms1 payers100% up
  99. 97datetime.openverbs.com/v1/parseParse an ISO 8601 duration such as 'P1Y2M10DT2H30M' into its components. Returns a normalized ISO string and totalSeconds — but totalSeconds is null when the duration contains years or months, because those are calendar-variable (use /v1/add or /v1/between for exact date math).$0.002 Base65 ms1 payers100% up
