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 containing the shuffled list of items with a count, a status of 'pass', an evidence block confirming no data was retained and no external calls were made, the SHA-256 hash of the input for verifiability, and a schema identifier.
Example use cases
Reproducible tournament bracket seeding
“I need to randomly order these 8 team names ['Eagles','Lions','Bears','Wolves','Sharks','Foxes','Hawks','Owls'] for a tournament bracket, using the seed 'season2024' so the draw is reproducible and anyone can verify it.”
Deterministic quiz question ordering
“Shuffle these 5 quiz questions ['Q1','Q2','Q3','Q4','Q5'] with the seed 'quizA-attempt1' so every student who gets the same attempt code sees the same order.”
Verifiable random assignment of tasks
“Take this list of tasks ['design','backend','testing','docs'] and shuffle them with seed 'sprintweek12' so we can fairly and reproducibly assign them to team members and prove the order wasn't manipulated.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-shuffle?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible, and verifiably tamper-free shuffle of a list — especially in agent workflows where auditability matters (e.g. tournaments, lotteries, task assignment). Prefer it over in-process shuffles when you need cryptographic evidence of fairness (input hash, no external calls, no data retention) and when paying per-result without signup friction is acceptable via x402/USDC.
Side effects
- Items array exceeds 256 items — request rejected
- Seed or item string exceeds 8192 character limit — request rejected
- Malformed JSON input — bad request error
- Payment not received or insufficient USDC — 402 Payment Required
- Network timeout during processing
