How this service works
Seeded Time Slot Pick: Seeded Time Slot Pick selects a reproducible slot from caller-provided time labels from bounded caller-supplied values without an external provider. Call Seeded Time Slot Pick when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Time Slot Pick as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First…
Output
Returns a JSON object containing the selected time slot string, its zero-based index in the input list, an operation identifier, a status of 'pass', and an evidence block confirming no data retention, zero external calls, and the SHA-256 hash of the input — ensuring verifiability and auditability of the deterministic selection.
Example use cases
Fair slot assignment for interview scheduling
“I have a list of open interview slots — '09:00', '10:00', '11:00', '14:00', '15:00' — and I want to deterministically assign one to candidate ID 'cand-8812'. Use that ID as the seed and pick a slot for them.”
Reproducible appointment booking for patients
“We need to assign a consultation time to patient 'pt-20048' from these available slots: ['08:30','09:30','11:00','13:00','16:00']. Use their patient ID as the seed so the same slot comes back every time we run this.”
Deterministic time slot lottery for event registrations
“I have 200 registrants and a handful of workshop slots — '10:00','13:00','15:00' — and I need to assign each person a slot reproducibly. Start with registrant seed 'reg-001' and pick their slot from that list.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-time-slot-pick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reproducible, auditable, seed-driven selection of a single time slot from a bounded list — especially when the same seed must always yield the same slot (idempotent assignment), when you need an audit trail via input hash, and when no external state or randomness should be involved. Prefer over random selection when fairness, reproducibility, or auditability is required.
Side effects
- Empty slots array — no slot can be selected, likely returns an error or null result
- Seed too long — exceeds maxLength of 8192 characters
- Slots list exceeds 256 items — request rejected by schema validation
- Malformed input JSON — returns 400 or schema validation error
- Network or service unavailability — returns 5xx error
