How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the list of winning labels, the count of winners drawn, a monetary_claim flag, the SHA-256 hash of the input for auditability, confirmation that no data was retained, and the number of external calls made (always 0).
Example use cases
Raffle winner selection for giveaway
“I have 10 entrants in my giveaway — ['Alice','Bob','Carol','Dave','Eve','Frank','Grace','Hank','Iris','Jack'] — use seed 'promo-july4' and draw 3 winners for me, with verifiable proof.”
Fair team assignment in a contest
“Pick 1 winner from ['TeamAlpha','TeamBeta','TeamGamma','TeamDelta'] using seed 'finals-round2' so the result is reproducible and auditable.”
Reproducible sample selection for testing
“From this list of user IDs ['u001','u002','u003','u004','u005','u006','u007','u008'], use seed 'test-batch-42' and randomly draw 3 of them for my A/B test sample — I need to be able to reproduce this selection later.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-lottery-draw?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible, and verifiable random draw from a labeled list — especially when auditability matters (contests, raffles, fair selection). The SHA-256 input hash and no-retention guarantee make it suitable for trust-sensitive use cases. Prefer this over general RNG when you need proof of fairness and a seeded result that can be independently reproduced.
Side effects
- draw_count exceeds the number of labels provided — likely returns an error or empty winners
- missing required fields (seed, labels, draw_count) — returns validation error
- labels array exceeds 256 items — rejected by schema
- seed or label strings exceed 8192 character limit — rejected
- payment not received via x402 — request returns 402 Payment Required
