# Get a Transaction Output by Hash and Index
Get a transaction output by a user-defined transaction hash and the transaction output index.
### **Compute Unit Value**: `10` (fixed)
***
> 🚧 Truncation Info
>
> For responses that have big numbers (such as in transfer amounts from blockchain transactions), truncation might be applied from Javascript’s native JSON parser.
>
> To avoid this behavior, we recommend using a library such as [`json-bigint`](https://github.com/sidorares/json-bigint) or [`lossless-json`](https://github.com/josdejong/lossless-json)
