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
A JSON object with a single 'date' field containing the computed date in YYYY-MM-DD format, e.g. {"date":"2026-10-07"}. The result reflects UTC calendar arithmetic.
Example use cases
Deadline calculation for project planning
“My project starts on 2025-06-01 and the deliverable is due 90 days later — what's the exact deadline date?”
Subscription expiration date lookup
“A user signed up on 2025-01-20 for a 365-day subscription — what date does their subscription expire?”
Historical date lookback for analytics
“I need to know what date was 180 days before 2025-07-04 so I can set the start of my analysis window.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/date/add-days?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, serverless date arithmetic computation — especially within automated workflows or agent pipelines that need to calculate deadlines, expirations, or scheduling windows without running local date logic. It is particularly useful when the agent environment lacks a trusted local date library or when a verifiable, paid computation record is desired via x402.
Side effects
- Invalid date format (not YYYY-MM-DD) returns an error
- Days value outside range -1000000 to 1000000 returns a validation error
- Malformed JSON body returns a parse error
- Missing required fields (date or days) returns an error
