How this service works
Seeded Lottery Draw: Seeded Lottery Draw draws unique labels reproducibly from a caller-owned pool without monetary claims from bounded caller-supplied values without an external provider. Call Seeded Lottery Draw 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 Lottery Draw as versioned deterministic JSON. Price: $0.001 USDC via x402 o…
Output
Returns a JSON object containing the list of drawn winners, the count of winners drawn, a boolean indicating whether a monetary claim is involved, plus evidence metadata including whether inputs were retained (always false), a SHA-256 hash of the input for auditability, and the number of external calls made (always 0).
Example use cases
Raffle winner selection for giveaway
“Run a seeded lottery draw with seed 'launch-raffle-42' from this list of entrants: ['Alice','Bob','Carol','Dave','Eve','Frank'] and draw 3 winners — I want it reproducible so I can verify later.”
Random task assignment for agent fleet
“I have 5 agent IDs — ['agent-1','agent-2','agent-3','agent-4','agent-5'] — and I need to randomly assign 2 of them to a high-priority job. Use seed 'job-batch-99' so the pick is auditable.”
Blind A/B variant selection
“From the variants ['control','variant-A','variant-B'], draw 1 winner using seed 'experiment-2024-07-01' so the selection is deterministic and I can replay it.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-lottery-drawWhen to prefer
Choose this endpoint when you need a deterministic, reproducible, and auditable random draw from a labeled list — particularly when you must replay or verify the result later using the same seed. It is ideal for agent workflows requiring fair selection (raffles, task assignment, A/B testing) without relying on external randomness sources. Prefer it over general RNG when auditability via SHA-256 input hashing matters.
Side effects
- draw_count exceeds the number of labels provided — returns an error or empty/partial draw
- missing required fields (seed, labels, or draw_count) — returns a validation error
- labels array exceeds 256 items — rejected by schema limit
- seed or label strings exceed 8192 character limit — rejected
- malformed JSON body — returns a parse error
