How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the selected time slot string and its index in the input array, a pass/fail status, the operation schema identifier, and an evidence block containing a SHA-256 hash of the input, a flag confirming no data was retained, and the count of external calls made (zero).
Example use cases
Fair meeting time allocation
“I have a list of available slots — '09:00', '10:00', '11:00', '14:00' — and I want to pick one fairly using the seed 'meeting-week42'. Make sure the choice is reproducible and auditable.”
Agent scheduling without bias
“My scheduling agent needs to deterministically assign a session slot to a user. Use the seed 'user-7731' and pick from ['08:00', '12:00', '15:00', '17:00'] — the same seed should always return the same slot.”
Reproducible appointment slot selection
“Given the seed 'booking-xyz9' and available appointment times ['09:30', '11:00', '13:30', '16:00'], pick one time slot in a way I can verify later that no data was retained.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-time-slot-pick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible, and verifiable selection of a time slot from a finite list — especially in agentic workflows where auditability, fairness, and no-data-retention guarantees matter. Prefer it over random selection when the same seed must always produce the same result, or when you need a cryptographic evidence trail (SHA-256 of input) to verify the decision was made correctly.
Side effects
- Empty slots array returns an error or undefined result
- Seed exceeds maxLength of 8192 characters causing rejection
- Slots array exceeds 256 items causing a validation error
- Invalid JSON body causes a 400-level response
- Payment not attached or insufficient USDC causes a 402 response
