How this service works
Calendar & scheduling for AI agents
Output
Returns a JSON object with a boolean `has_conflict` field indicating whether any scheduling conflict exists, and a `conflicts` array listing each overlapping event with its title, start/end times, and the specific overlap window (overlap_start and overlap_end).
Example use cases
Pre-booking conflict detection
“Before I accept this interview invite for Thursday from 2pm to 3pm, can you check if I have any conflicting events already on my calendar?”
AI assistant scheduling guard
“I want to set up a team sync every Monday from 9am to 10am — can you scan my calendar and flag any existing events that would conflict with that recurring slot?”
Back-to-back meeting check
“I have a call ending at 11am and want to schedule another from 10:30am to 12pm — will those overlap, and if so, what event is in the way?”
Technical details
Endpoint
POSThttps://beautiful-nature-production-a883.up.railway.app/conflict-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to verify scheduling feasibility before booking or proposing a meeting time — particularly when you need precise overlap windows, not just a yes/no answer. Prefer this over generic calendar APIs when you need structured conflict data including which specific events overlap and by how much. Ideal for agentic workflows that automatically propose, validate, and book meetings without human intervention.
Side effects
- Missing or malformed time range input returns a 400 validation error
- Non-ISO-8601 date formats may cause parsing failures
- Empty or missing calendar event list results in no conflicts detected even if conflicts exist
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Server unavailability on Railway infrastructure returns 5xx errors
