How this service works
Web standards and time reference for AI agents: HTTP status codes with what the client should do, retry semantics, MIME types and content-type matching, request-method safety and idempotency, plus deadline arithmetic - time until a moment, weekday and business-day checks, duration conversion and Unix timestamps. Pay per call in USDC on Base via x402 or USDC on Tempo via MPP. No signup, no API key, no KYC.
Output
Returns a structured description of the requested instant, including the day of the week, whether it falls on a business day, the resolved timezone, and a human-readable summary of the moment. May also include Unix timestamp and ISO 8601 representation.
Example use cases
Business day check for scheduling
“Is 2025-12-25T00:00:00Z a business day in UTC? Describe that instant for me so I know whether to schedule a payment run on that date.”
Weekday lookup for a future date
“What day of the week is 2026-01-01T12:00:00Z? Give me a full description of that moment in UTC.”
Tehran timezone instant description
“Describe the instant 2025-03-20T20:29:00Z in the Tehran timezone — I want to know the weekday and whether it's a business day there.”

Endpoint
GEThttps://webref.johnaio281.workers.dev/api/time/describe_instant?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call lookup of what a specific timestamp represents — its weekday, business-day status, and timezone label — without needing to set up credentials or an API key. Particularly useful for agents handling scheduling, deadline checks, or calendar logic that need authoritative time-context data on demand.
Side effects
- Missing or malformed 'at' query parameter returns an error about invalid input
- Unsupported timezone value (not 'utc' or 'tehran') returns a validation error
- Invalid HTTP method (e.g. POST) returns 405 Method Not Allowed
- Unparseable timestamp string returns a 400 Bad Request
- Payment not received results in a 402 Payment Required response
