# cosmos-sdk-historical-query
Sample code for querying a Cosmos chain at a historical block height, in four languages:
- Rust
- Go
- JavaScript
- Bash
In addition, the example persented here is a paginated query, meaning it may take more than one query to retrieve the full result. We show how to do this using a loop.
## How to use
Rust:
```bash
cd rust
cargo run
```
Go:
```bash
cd go
go run main.go
```
JavaScript:
```bash
cd js
node main.js
```
Bash:
```bash
cd bash
bash main.sh
```
Result should look like this:
```plain
performing query... next=""
performing query... next="14614fecb276f5e00c2fd0db40130023bb3f832175"
performing query... next="14ab2bc85eaa365c4cf39f6a7525b44fef8264512e"
performing query... next="14dbfdb0af1e9dc4a05a94074e6c900b29550b2dad"

}
},
...more
```
If the node has already pruned the height you're querying at, an error like this should be returned:
```plain
codespace: sdk
code: 18
log: failed to load state at height 123; version mismatch on immutable IAVL tree; version does not exist. Version has either been pruned, or is for a future block height (latest height: 344122): invalid request
```
