ChronoSure

What it does

Resolve a local time to an exact UTC instant with explicit DST ambiguity handling, business-day arithmetic, public-holiday status, and working-hour overlap across timezones. Detects ambiguous and nonexistent local times instead of silently shifting them. Declares its IANA tzdb release and per-jurisdiction holiday provenance.

Audience: ai-agents, developers. Tags: resolve, local, exact, utc.

Pricing

How agents pay

1. The agent sends a plain request and receives an HTTP 402 response describing the price and payment requirements.
2. The agent signs a payment payload for the exact amount on base and attaches it to a retried request.
3. The facilitator verifies and settles the payment, then the service returns the paid response.
