Retrieves the full receipt for a blockchain transaction by hash, including status, gas usage, block info, and execution metadata across multiple networks.

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 skills-onesource-io-593b3274
```

Example prompt: Can you pull the transaction receipt for 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 on Ethereum — I want to see if it succeeded, how much gas it used, and what block it landed in?

## When to prefer this

Use this endpoint when you need to confirm transaction execution status, verify gas consumption, find the block a transaction landed in, or retrieve event logs emitted by a smart contract call — specifically when you have a transaction hash and need the canonical on-chain receipt. Supports Ethereum mainnet, Sepolia, Avalanche, MegaETH, MegaETH testnet, and Base.

## Known failure modes

- Invalid transaction hash format (must be 0x-prefixed 64-character hex) returns validation error
- Transaction hash not found on the specified network returns null or 404
- Unsupported network value returns enum validation error
- Transaction is still pending (not yet mined) may return null receipt
- Network congestion or RPC timeout may cause slow or failed responses

## How this service works

Retrieves the receipt for a blockchain transaction hash, including status, gas usage, block information, and execution metadata.

## Output

Returns a transaction receipt object including: to/from addresses, transaction status (0x1 = success, 0x0 = failure), gas used (hex), block hash, block number, contract address (if deployment), logs array, logs bloom filter, and transaction type. All numeric values are hex-encoded.
