# Batch Result Summary

> Batch Result Summary is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Summarizes success, failure, pending, and unknown statuses across a batch of results, returning counts and normalized values as versioned deterministic JSON.

## Facts

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

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 batch-result-summary-c9d88055 -d '<json body>'
```

Example prompt: Can you summarize these batch results for me — I have a mix of succeeded, failed, and pending items and I need a clean count of each status before I pass the data downstream?

## When to prefer this

Use this endpoint when you need a fast, deterministic, in-memory status summary of a batch before passing data to a stricter downstream tool or contract. Prefer it over custom aggregation logic when you need versioned, normalized output with no side effects and guaranteed in-memory-only processing. Best suited for agent pipeline preflight checks where a structured count of success/failure/pending/unknown statuses is required without any external dependency.

## Known failure modes

- Input array exceeds 256 items — request rejected with validation error
- Individual result objects exceed 128 properties — may be truncated or rejected
- Malformed or non-object items in results array — may be classified as unknown status
- Missing or empty results array — returns zero counts across all categories
- Payment not included or insufficient USDC — 402 Payment Required

## How this service works

Batch Result Summary: summarizes success, failure, pending, and unknown batch statuses using only bounded caller-supplied values. Call when you need a bounded batch result summary result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Result Summary as versioned deterministic JSON. Price: $0.001 USDC via x402 on B…

## Output

Returns a versioned deterministic JSON object containing counts for each status category (success, failure, pending, unknown), normalized status values for each input result, and a versioned result contract schema identifier — all computed in-memory from the supplied batch without external calls or data retention.
