# JSON-RPC API

GetBlock provides fast and reliable access to Akash nodes via the CometBFT JSON-RPC API. Connect to the Akash network without running your own infrastructure.

The CometBFT JSON-RPC interface for Akash: consensus and node status, block and transaction data, mempool, transaction broadcast, and `abci_query` for reading any Cosmos SDK or Akash module state. All methods are JSON-RPC 2.0 POST requests to the endpoint base URL.

### Akash specifics

* **Shared nodes are pruned.** Heights below roughly 26,980,292 are not retained and return `-32603 Internal error` naming the lowest available height. Read the floor from [status](/api-reference/akash-akt/json_rpc-api/status.md) under `sync_info.earliest_block_height`.
* **Hash encodings differ per method.** [block\_by\_hash](/api-reference/akash-akt/json_rpc-api/block_by_hash.md) and [tx](/api-reference/akash-akt/json_rpc-api/tx.md) take the hash **base64-encoded**, while [header\_by\_hash](/api-reference/akash-akt/json_rpc-api/header_by_hash.md) takes the **plain hex** form. A `0x` prefix is rejected by all three.
* **Wide queries time out.** A [block\_search](/api-reference/akash-akt/json_rpc-api/block_search.md) spanning millions of heights returns a gateway timeout; narrow the range and keep `per_page` small.
