How this service works

Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.

Technical details

Endpoint

POSThttps://x402.nichospt.net/timezone-math?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to convert a specific datetime (structured or natural language) between IANA timezones and want both a machine-readable ISO result and a human-readable string. Especially useful when the user phrases the time in natural language like '3pm PT next Thursday'. Prefer this over generic date libraries when you need server-side parsing of relative phrases against a reference date, or when you need the offset difference explicitly returned.

Side effects

Invalid or unrecognized IANA timezone string returns an error
Ambiguous natural language query that cannot be parsed returns an error
Providing both 'query' and 'datetime'/'from' simultaneously (mutually exclusive inputs) returns a validation error
Missing required 'to' field returns a validation error
Payment not settled via x402 protocol returns a 402 Payment Required response
