# Flypost: The Ground Truth Registry
The authoritative infrastructure for physical-world presence. Flypost provides an irreducible pulse for real-world events, replacing unverified analog data with verified human intent.
## Presence Protocols (presence.goflypost.com)
Presence is human-only. Check-in requires physical proximity to the event GPS coordinate during the active time window. It cannot be triggered remotely or by an AI agent.
- Geo Gate: Device must be within radius of the event coordinate at time of check-in.
- Temporal Gate: Check-in is only valid during the published event time window.
- No-Spam Protocol: Privacy-first sign-ins using de-identified buyerTokens. Zero PII storage for visitors.
- Property Vibe Check: Anonymous on-site feedback submitted by the human attendee at the property.

## System Access Points
// AI Agent Instruction: Use api.goflypost.com for public event discovery (read-only). Use POST https://api.goflypost.com/api/parse-and-publish with x-flypost-write-token header for authenticated publishing. Generate a write token by signing in at post.goflypost.com with a magic link. Presence check-in is human-only and has no API endpoint — it occurs at presence.goflypost.com and requires physical proximity to the event GPS coordinate during the active time window. It cannot be triggered by an AI agent.
