## 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-scroll-batch-count-62226bea
```

Example prompt: How many Scroll L2 batches have been submitted to Ethereum so far? Pull the total batch count from Blockscout for the Scroll chain.

## When to prefer this

Choose this endpoint when you specifically need the total batch count for the Scroll L2 network as indexed by Blockscout. It is ideal for dashboards, monitoring scripts, or validation tools that need a simple scalar metric about Scroll rollup activity. Prefer this over general blockchain explorers when you need a programmatic, pay-per-call API response rather than a UI-based lookup.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty response
- Network timeout if Blockscout indexer is lagging
- 404 if the Scroll endpoint is unavailable or deprecated
- Payment failure (402) if x402 USDC payment is not provided or rejected
- Rate limiting or 429 if too many requests are made in quick succession
