# Delx Commerce Batch Concurrency Plan

> Delx Commerce Batch Concurrency Plan is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Computes the optimal wave structure (number of waves, concurrency per wave, and last wave size) for processing a batch of items at a given concurrency level.

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/batch-concurrency-plan?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-commerce-batch-concurrency-plan-bfcc2490

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-batch-concurrency-plan-bfcc2490 -d '<json body>'
```

Example prompt: I need to process 100 items with a concurrency of 8 — how many waves will that take and how big will the last wave be?

## When to prefer this

Choose this endpoint when an AI agent or workflow orchestrator needs to deterministically plan how to chunk a fixed number of items into concurrent execution waves — especially when verifiable, tamper-evident computation (via SHA-256 evidence) is needed and no local math library is available. It is ideal for pay-per-use scenarios where no signup or standing API key is required.

## Known failure modes

- Missing required fields (item_count or concurrency) results in a validation error
- Zero or negative concurrency value may cause division errors or rejection
- item_count of zero may return trivial or error response
- Payment failure via x402 protocol blocks the request before computation
- Malformed JSON body returns HTTP 400

## 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 number of waves required, the concurrency per wave, and the size of the last (potentially partial) wave. Also includes a verifiable evidence block with the input SHA-256 hash, a flag confirming no data is retained, and the count of external calls made (always 0 for this pure computation).
