How this service works
Cheap, deterministic utilities for AI agents, paid per call in USDC with x402 (no account, no API key): ECB euro reference FX rates and conversion, IANA time-zone conversion with explicit DST handling, European public holidays and working-day calculator (FR incl. Alsace-Moselle, BE, LU, DE, AT, IT, ES, PT), offline IBAN validation, and SIREN/SIRET and EU VAT number check-digit validation. Errors are never charged.
Output
A JSON object with a status field ('ok', 'ambiguous', or 'invalid') and either a single converted datetime or an array of candidate datetimes (when DST ambiguity occurs), each including the UTC equivalent and the ISO 8601 representation in both source and target zones.
Example use cases
Cross-timezone meeting scheduler
“I'm in Paris and want to schedule a call at 09:00 on March 28, 2026 — what time is that in America/Chicago so I can send the invite?”
DST ambiguity detection
“I need to convert 2026-10-25T02:30 in Europe/London to UTC, but I'm worried it might be ambiguous because of clocks going back — can you tell me all the possible UTC equivalents?”
Convert server log timestamp to local time
“This log timestamp says 2025-11-02T15:45:00Z — what is that in Asia/Tokyo local time?”
Technical details
Endpoint
GEThttps://eu-agent-utils.frcompanycheck.workers.dev/v1/time/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, DST-aware timezone conversion with explicit handling of ambiguous wall-clock times (e.g. clocks-back transitions). Ideal for AI agents that must schedule or timestamp events across European and global timezones without setting up accounts or managing API keys. The x402 micropayment model ($0.001 USDC per call) makes it suitable for high-frequency, per-call agent workloads. Prefer over general-purpose libraries when you need a hosted, stateless, auditable conversion with no infrastructure overhead.
Side effects
- Invalid or unrecognized IANA timezone name returns an error (not charged)
- Malformed ISO 8601 datetime string returns a validation error (not charged)
- Ambiguous DST wall-clock time returns status 'ambiguous' with multiple candidate results
- Missing required 'datetime' or 'to' parameters returns a 400-level error
