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 transaction-receipts-by-block-f2ff9c82 -d '<json body>'
```

Example prompt: Can you pull all the transaction receipts for block 0x12A05F200 on eth-mainnet so I can see which transactions succeeded and how much gas each one used?

## When to prefer this

Use this endpoint when you need receipt data for ALL transactions in a block at once, rather than querying receipts one by one. Ideal for block-level analytics, gas profiling, log aggregation, or auditing which transactions in a block succeeded or failed. Prefer over individual eth_getTransactionReceipt calls when processing an entire block.

## Known failure modes

- Invalid or unsupported network slug returns an error
- Block hash or block number not found on the specified network
- Both blockHash and blockNumber omitted with only network provided — ambiguous request
- Block number not in valid hex format causes parsing error
- Network congestion or Alchemy upstream timeout may delay response
- Requesting a very recent block before it is fully indexed may return empty or partial results

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

An object containing all transaction receipts for the specified block, including per-transaction data such as status (success/failure), gas used, logs emitted, contract addresses created, and transaction hashes.
