Delx Seeded Bootstrap Sample
x402
Delx Seeded Bootstrap Sample is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Generates a reproducible bootstrap sample of integer indices from a seeded random source, with replacement, given a seed string and item/sample counts.

How this service works
Seeded Bootstrap Sample: Seeded Bootstrap Sample samples indices with replacement for a reproducible bootstrap set from bounded caller-supplied values without an external provider. Call Seeded Bootstrap Sample 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 Bootstrap Sample as versioned deterministic JSON.

Output
Returns a JSON object containing an array of sampled integer indices (with replacement), a schema identifier, a pass/fail status, and an evidence block that includes whether data was retained (always false), the SHA-256 hash of the input, and the count of external calls made (always 0) — enabling full auditability of the computation.
Example use cases
Reproducible cross-validation splits
“I want to create reproducible train/test index splits for my 10-item dataset — use seed 'cv-run-1', item count 10, and sample count 8 with replacement.”
Simulation resampling for statistical tests
“Run a bootstrap resample for my simulation: seed it with 'sim-2024-q1', pick from 20 items, and draw 20 samples with replacement so I can reproduce the result later.”
Deterministic random assignment for A/B testing
“I need to randomly assign 6 slots from a pool of 6 items for an A/B test — seed it with 'ab-test-cohort-3' so the assignment is always the same when I rerun it.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-bootstrap-sampleWhen to prefer
Choose this endpoint when you need a reproducible, auditable bootstrap sample with a fixed seed — especially in agent workflows where determinism and auditability matter. Prefer it over local random sampling when you need a tamper-evident SHA-256 input hash and a guaranteed no-retention, no-external-calls evidence trail. It is well-suited for statistical resampling, simulation loops, and deterministic A/B splits where the same seed must always produce the same indices.
Side effects
- Missing required fields (seed, item_count, or sample_count) return a validation error
- item_count or sample_count of zero or negative values may produce empty or error responses
- Seed strings exceeding 8192 characters are rejected
- Network or payment (x402) failures prevent execution and return HTTP 402 or 5xx errors
- Malformed JSON body returns a 400 bad request
