# Delx Commerce — Seeded Bootstrap Sample

> 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.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-seeded-bootstrap-sample-e2f4413a -d '<json body>'
```

Example prompt: Run a seeded bootstrap sample using seed 'experiment-42', picking 5 samples from a pool of 10 items, and give me the resulting indices.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
