# Delx Commerce — Batch Result Summary

> Delx Commerce — Batch Result Summary is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-03).

Accepts an array of operation results and returns aggregated counts by status (success, failed, pending, unknown) with a verifiable in-memory summary.

## Facts

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

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_aM-JMjYLDO_JFQ1-2w8Ci

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-result-summary-7ca4b4e8 -d '<json body>'
```

Example prompt: I just ran a batch of 50 tasks and have an array of their result objects — can you summarize how many succeeded, failed, or are still pending?

## When to prefer this

Choose this endpoint when you need a lightweight, verifiable, pay-per-call aggregation of batch result statuses without storing data externally. It is ideal for agent pipelines that require tamper-evident audit trails (via SHA-256 input hash) and no-retention guarantees, and when you want an exact flat-fee computation rather than building custom aggregation logic.

## Known failure modes

- Array exceeds 256 items — request rejected
- Individual result objects exceed 128 properties — may be rejected
- Malformed JSON input — 400 error
- Payment not received or insufficient USDC — 402 error
- Empty results array — may return zero counts with a pass status

## 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 total number of results, counts broken down by status (success, failed, pending, unknown), the operation name, a pass/fail status, and an evidence block with the input SHA-256 hash and a flag confirming no data was retained externally.
