Timezone Fixed Offset Format is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).
Formats a UTC offset in minutes into a human-readable ±HH:MM string using local math, no external dependencies.

How this service works
Format a fixed UTC offset as ±HH:MM. Call when agents need offset labels without full IANA DB. Returns offset string as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
A deterministic JSON response containing the formatted UTC offset string in ±HH:MM notation, computed purely from local arithmetic with no external lookups.
Example use cases
Display offset in scheduling UI
“I need to show a user-facing timezone offset label for UTC-5 hours — convert -300 minutes to the ±HH:MM format for me.”
Label offset in exported calendar event
“My calendar export needs a fixed offset string for UTC+5:30, which is 330 minutes — can you format that as ±HH:MM?”
Format offset for API response field
“I'm building an API response and need to render a UTC offset of 60 minutes as a proper ±HH:MM string — can you format that for me?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/tz-offset-fixed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, deterministic ±HH:MM offset label from a known minute count and do not need full IANA timezone database lookups, DST rules, or timezone name resolution. Ideal for display formatting, API response fields, or calendar labels where the raw offset is already known.
Side effects
- Missing or non-integer offset_minutes field returns a validation error
- Offset value outside realistic UTC range (e.g. beyond ±840 minutes) may return an error or unexpected result
- Payment failure via x402 results in a 402 response before computation occurs
