How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with a single integer field `days` representing the number of calendar days between the start and end dates interpreted in UTC (e.g. {"days": 4}).
Example use cases
Project deadline countdown
“How many days are left between today, 2025-07-10, and our project deadline on 2025-09-30?”
Age or anniversary calculation
“Can you tell me how many days it's been since my company was founded on 2019-04-22, counting up to today, 2025-07-10?”
Event duration measurement
“Our conference runs from 2025-08-05 to 2025-08-19 — how many days is that in total?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/date/difference-days?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, authoritative integer count of calendar days between two known UTC dates. Prefer it over in-context LLM arithmetic when precision matters and dates must be treated as UTC Gregorian. At $0.001 USDC per call it is cost-effective for frequent programmatic date-span calculations in workflows.
Side effects
- Invalid date format (not YYYY-MM-DD) returns an error
- Dates outside the Gregorian calendar range may fail
- Swapped start/end may return zero or negative result
- Missing required fields cause a validation error
- x402 payment not provided results in 402 Payment Required response
