# Blockscout ZKsync Batch List API

> Blockscout ZKsync Batch List API is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-12).

Retrieves a paginated list of ZKsync L2 batches with commit, prove, and execute transaction hashes and timestamps for a specified blockchain

## 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 blockscout-zksync-batch-list-api-3792d63b
```

Example prompt: Show me the latest ZKsync batches on chain ID 1101 — I want to see their batch numbers, statuses, and the commit and prove transaction hashes, paginated 25 at a time.

## When to prefer this

Use this endpoint when you specifically need ZKsync L2 batch-level data — including commit, prove, and execute lifecycle hashes — for a chain hosted on Blockscout. Prefer this over generic transaction lookup endpoints when the goal is rollup batch auditing, finality verification, or throughput analysis at the batch level.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty result
- Non-existent batch number returns empty items array
- Missing required path parameter chain_id causes a 404 or routing error
- Rate limiting or payment failure (402) if x402 payment not provided
- Network timeout on heavily loaded chains

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

Returns a paginated JSON object containing an array of ZKsync batch records, each with batch number, status string, timestamp, transaction count, commit/prove/execute L1 transaction hashes and their respective timestamps. Also includes next_page_params for cursor-based pagination.
