How this service works
Reconstruct availability-priority and normal free-busy overlay intervals. Reconstruct the fully typed result and compare its complete canonical SHA256 claim.
Output
Returns the fully typed reconstructed availability-priority and free-busy overlay partition result, including computed interval segments with their priority and busy-type assignments, along with a comparison result indicating whether the reconstruction's canonical SHA256 hash matches the supplied claim.
Example use cases
Calendar agent verifying free-busy merge
“I have a calendar availability window from timestamp 1699900000 to 1700000000 with three components at different priorities and a handful of busy blocks. Reconstruct the full RFC 7953 free-busy overlay partition and check it against this SHA256 claim: 'd4e2...8b1a'.”
Scheduling conflict detection across components
“Overlay these calendar components — 'meeting_room_A' at priority 0 available 1700100000–1700108000, 'meeting_room_B' at priority 3 available 1700103000–1700110000, both with BUSY-TENTATIVE type — within the window 1700090000 to 1700120000, and reconstruct the full priority-partitioned availability intervals.”
Free-busy integrity audit for synced calendars
“After syncing calendar data, I need to reconstruct the availability-priority overlay for the interval 1701000000 to 1701086400 with two components and their busy slots, then confirm the reconstruction matches this SHA256 fingerprint: 'c9d3...2f77'.”

Endpoint
POSThttps://detect.halowerk.com/v1/F-TD2000-DOCUMENTS-10/rfc7953-expanded-unique-priority-availability-busy-overlay-partition?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to implement RFC 7953 VAVAILABILITY semantics — specifically reconstructing priority-ordered availability intervals overlaid with free-busy data and verifying the output against a canonical SHA256 fingerprint. Prefer this over generic calendar APIs when you need deterministic, verifiable free-busy partitioning with typed busy classifications (BUSY, BUSY-UNAVAILABLE, BUSY-TENTATIVE) across multiple priority-ranked components.
Side effects
- Invalid timestamp ranges (end before start) return validation error
- SHA256 claim mismatch returns comparison failure with actual hash
- Component count exceeds maxItems:10 returns schema validation error
- Busy array exceeds maxItems:32 returns schema validation error
- Malformed component ID not matching pattern ^[A-Za-z_][A-Za-z0-9_.-]*$ returns rejection
- Null claim skips hash verification but reconstruction still proceeds
- Payment failure returns HTTP 402 requiring x402 USDC payment
