## 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 evm-block-receipts-all-transaction-receipts-in-one-block-1577abca -d '<json body>'
```

Example prompt: Pull all the transaction receipts for Ethereum block 21000000 — I need every receipt in that block in one shot.

## When to prefer this

Choose this endpoint when you need all transaction receipts for an entire block in a single call rather than fetching receipts one by one per transaction. It is ideal for block-level analytics, auditing, MEV detection, or any workflow that requires a complete view of block activity across Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, Gnosis, Linea, or Scroll.

## Known failure modes

- Invalid or non-existent block number returns an error
- Unsupported chain name causes validation failure
- Malformed block parameter (not a valid block hash or number) causes rejection
- Payment failure or insufficient USDC balance prevents the call from completing
- Chain temporarily unavailable or node lag may cause timeout or empty response

## How this service works
