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 reordered list of batch IDs under result.items, the operation name, a status of 'pass', and an evidence block including whether data was retained (always false), a SHA256 hash of the input for auditability, and the count of external calls made (always 0).
Example use cases
Fair lottery draw ordering
“I need to randomly order these 5 participant IDs — p1, p2, p3, p4, p5 — for a lottery draw, using the seed 'draw-2024-finals' so the result is reproducible and anyone can verify it. Can you run the seeded batch order?”
Reproducible A/B test assignment
“Shuffle these experiment variant IDs — varA, varB, varC — using the seed 'experiment-run-7' so we get the same order every time we rerun and can audit it later.”
Deterministic queue prioritization
“I've got a batch of job IDs — job001, job002, job003, job004 — and I need them reordered using the seed 'queue-seed-monday' to assign processing priority in a way that's fair and verifiable.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-batch-order?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, verifiable, and auditable shuffling of a list of batch IDs without any external data calls or server-side retention — ideal for fairness-critical scenarios like lotteries, A/B test assignments, or queue ordering where reproducibility and proof of non-manipulation matter. Prefer it over client-side shuffling when you need an on-chain payment trail and evidence hash for auditability.
Side effects
- Invalid or missing seed string returns validation error
- Batch IDs array exceeds 256 items limit returns error
- Malformed JSON body returns 400 bad request
- Payment not provided or insufficient USDC triggers 402 payment required
- Seed or batch ID strings exceeding 8192 character limit rejected
