How this service works
Qty converts known units for free and interprets messy quantities, prices, recipes, sizes, and dates in code. It never invents a number.
Output
Returns a JSON object containing a quantities array where each entry has a unit of 'date', a textValue with the resolved ISO date string (e.g. '2026-10-07'), and a definitionId indicating which date computation rule was applied (e.g. 'date.working_days.v1'). Also includes a see object with links to docs, MCP, and related discovery resources.
Example use cases
Contract deadline in working days
“Our contract says deliverables are due 30 working days after signing on January 6, 2025 — what exact calendar date does that land on?”
Payroll schedule calculation
“We pay employees 10 business days after the end of each month — what date should I schedule the next payroll run for if the month ends March 31 2025?”
Regulatory filing deadline
“The regulation says we have 60 working days from the audit trigger date of February 3 2025 to file our response — what is the actual deadline date?”
Technical details
Endpoint
GEThttps://qty.vercel.app/v1/date?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a guaranteed, deterministic date computation — especially for business day or working day offsets — and cannot risk an LLM hallucinating a wrong date. Ideal for contracts, compliance deadlines, scheduling, and payroll where exact dates are critical and must never be invented.
Side effects
- Missing required 'input' parameter returns a validation error
- Unrecognized or ambiguous date expression may return no quantities
- Invalid path query parameter causes processing failure
- Payment failure via x402 protocol blocks the request
- Network timeout on vercel.app serverless cold start
