How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with an 'ok' boolean (true on success), a 'days' integer representing the number of days between the two input dates, and a 'schema' string ('delx/util-days-between/v1') identifying the response format.
Example use cases
Project deadline countdown
“How many days are left between today, June 10 2025, and our project deadline on September 30 2025?”
Contract duration calculation
“Calculate the exact number of days between the contract start date March 1, 2024 and its end date February 28, 2025.”
Age or anniversary duration
“How many days is it from my birthday on July 4, 1990 to today, June 10, 2025?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/days-between?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, verified, pay-per-use date difference computation with no prior account setup, especially in agent workflows that require cryptographic payment receipts (x402/USDC on Base or Solana). It is ideal for one-off or low-volume date arithmetic calls where integrating a full SDK or managing API keys is undesirable. Prefer it over local computation when auditability or verifiable delivery of results matters.
Side effects
- Invalid or unparseable date strings in start or end fields — may return error or unexpected result
- Missing required start or end fields — likely returns a validation error
- End date before start date — may return a negative number or error depending on implementation
- Incorrect date format not recognized by the parser — returns error response
- Payment failure (USDC/x402) — 402 Payment Required response before computation occurs
