How this service works
Seeded Sample With Replacement: Seeded Sample With Replacement samples caller items reproducibly with replacement from bounded caller-supplied values without an external provider. Call Seeded Sample With Replacement 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 Sample With Replacement as versioned deterministic JSON. Price: $0.001 US…
Output
Returns a JSON object with a 'result.items' array containing the sampled items (possibly with repeats), along with schema identifier, pass/fail status, and an evidence block confirming no data was retained, the SHA-256 of the input, and zero external calls were made.
Example use cases
Bootstrap sampling for statistical analysis
“I need to bootstrap sample my dataset — take these 10 items ['a','b','c','d','e','f','g','h','i','j'] and draw 20 samples with replacement using seed 'boot42' so I can reproduce this later.”
Reproducible random question assignment
“I have a question bank ['Q1','Q2','Q3','Q4','Q5'] and I need to randomly assign 8 questions to a test, with replacement allowed, using seed 'exam2024' so every run gives the same set.”
Deterministic random playlist shuffle with repeats
“Shuffle this playlist ['track_a','track_b','track_c','track_d'] and pick 10 tracks with replacement using seed 'shuffle99' — I need the same order each time I run it.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-sample-with-replacementWhen to prefer
Choose this endpoint when you need a deterministic, reproducible random sample with replacement — especially for bootstrapping, simulation, or test generation where the same seed must always yield the same output. Prefer it over non-seeded random samplers when reproducibility is required, and over shuffle-only endpoints when sampling more items than the original list size is needed.
Side effects
- Invalid seed type (non-string) returns validation error
- Count exceeding reasonable bounds may be rejected
- Items array exceeding 256-item maximum returns a 400-level error
- Missing required fields (seed, count, or items) returns a schema validation error
- Payment not included or insufficient USDC triggers a 402 response
