# getStakeMinimumDelegation

> Returns the minimum number of lamports required to delegate a stake account.

Source: https://docs.constant-k.com/rpc/http/getstakeminimumdelegation/

`getStakeMinimumDelegation` returns the runtime-enforced floor on how small a stake delegation can be. Any `DelegateStake` instruction that would leave a stake account below this amount is rejected by the Stake program.

Wallets and staking UIs typically call it before submitting a delegate instruction, validating the amount client-side instead of round-tripping a doomed transaction.

- Transport: HTTP, JSON-RPC 2.0 `POST` to `https://rpc-newyork.constant-k.com/?api-key=YOUR_API_KEY` (New York) or `https://rpc-frankfurt.constant-k.com/?api-key=YOUR_API_KEY` (Frankfurt) or `https://rpc-amsterdam.constant-k.com/?api-key=YOUR_API_KEY` (Amsterdam). The key also works as an `x-api-key` header.

## Parameters

`params` is a positional JSON array, in this order:

- `config` (object, optional): Commitment configuration.
  - `commitment` (string, optional, one of `finalized`, `confirmed`, `processed`, default `"finalized"`): Bank state to read the runtime parameter from.

## Result

- `result` (object, optional): The minimum delegation amount, wrapped with context.
  - `context` (object, required)
    - `slot` (integer, optional): Slot the value was read at.
    - `apiVersion` (string, optional): Version string of the responding node.
  - `value` (integer, required): Minimum stake delegation, in lamports.

## Example: Get minimum stake delegation

Request:

```bash
curl "https://rpc-newyork.constant-k.com/?api-key=YOUR_API_KEY" \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getStakeMinimumDelegation",
    "params": []
  }'
```

Response:

```json
{
  "jsonrpc": "2.0",
  "result": {
    "context": {
      "apiVersion": "4.3.0-rc.0",
      "slot": 447946664
    },
    "value": 1000000000
  },
  "id": 1
}
```

## Notes

- This is a runtime constant, currently 1 SOL (1,000,000,000 lamports), applied network-wide rather than varying per validator or epoch.
