Delx Commerce — Seeded Bootstrap Sample
x402
Delx Commerce — Seeded Bootstrap Sample is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Generates a reproducible bootstrap sample of indices given a seed, item count, and sample count, returning the sampled indices with verifiable evidence of no data retention.

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 an array of sampled indices (with replacement), a schema identifier, a status field ('pass'), and an evidence block that includes the input SHA256 hash, a flag confirming no data was retained, and the count of external calls made (always 0). This allows full auditability and reproducibility of the bootstrap draw.
Example use cases
Reproducible ML cross-validation splits
“I need to create a reproducible bootstrap sample for cross-validation — use seed 'cv-run-7', draw 100 samples from 500 items, and return the indices so I can replicate this experiment later.”
Auditable A/B test randomization
“For our A/B test audit, generate a seeded bootstrap sample with seed 'ab-test-2024-q1', selecting 50 samples out of 200 items, so we can verify the randomization was fair.”
Statistical bootstrap confidence interval
“I want to compute a bootstrap confidence interval — give me 1000 bootstrap sample indices drawn from 80 observations using seed 'bootstrap-ci-99'.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-bootstrap-sample?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, reproducible bootstrap sample with cryptographic evidence of no data retention — especially useful for auditable machine learning experiments, statistical resampling, or any workflow where reproducibility and tamper-evidence matter. Prefer this over a local random sampler when you need a pay-per-use, zero-signup, on-chain verifiable result delivered via x402 micropayment.
Side effects
- Invalid or missing seed string causes a validation error
- item_count or sample_count not provided as integers results in schema validation failure
- Extremely large item_count or sample_count values may exceed bounded computation limits
- Payment failure via x402 protocol results in 402 response before computation begins
- Malformed request body returns a 400 error
