How this service works
Whole days between two ISO dates. Call when you compute agent SLA windows or age. Returns days and ok for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object with a numeric 'days' field representing the whole number of days between the two ISO dates, and an 'ok' boolean indicating success. No external data sources are used; computation is local and deterministic.
Example use cases
SLA window calculation for agent
“My contract started on 2024-03-01 and ends on 2024-09-15 — how many whole days is that SLA window?”
Customer subscription age check
“A user signed up on 2023-11-20 and today is 2024-06-10 — how many days old is their subscription?”
Days until project deadline
“How many whole days are left between today, 2024-06-12, and our project deadline on 2024-08-01?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/days-betweenWhen to prefer
Choose this endpoint when you need a simple, deterministic, fee-based local computation of whole days between two ISO dates — especially for agent SLA windows, subscription age, or deadline countdowns — with no external API keys, no data retention, and a predictable $0.001 USDC per-call cost.
Side effects
- Invalid or non-ISO date strings in start or end fields return an error
- Missing start or end parameter causes a bad request
- Reversed date order (end before start) may return a negative value or error
- Payment failure via x402 protocol blocks the request
