# fetchHasAnnouncedL1EarlyExit

Checks whether a staker has announced an L1 early exit for a protocol bond. Wraps the pox-5 read-only `has-announced-l1-early-exit`, which reads the `protocol-bond-l1-early-exit-announced` map.

***

### Usage

```ts
import { fetchBondMembership, fetchHasAnnouncedL1EarlyExit } from '@stacks/bitcoin-staking';

async function hasAnnounced(staker: string) {
  const bond = await fetchBondMembership({ address: staker, network: 'mainnet' });
  if (!bond) return false;
  return fetchHasAnnouncedL1EarlyExit({ bondIndex: bond.bondIndex, staker, network: 'mainnet' });
}
```

#### Notes

* `announce-l1-early-exit` sets the flag ([announce-l1-early-exit](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L1241-L1246)) and reverts with `ERR_L1_EARLY_EXIT_ALREADY_ANNOUNCED (u50)` when it is already set ([announce-l1-early-exit](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L1226-L1228)). Check it before [buildAnnounceL1EarlyExit](/reference/stacks.js/stacks-bitcoin-staking/build/buildannouncel1earlyexit.md).
* No pox-5 function clears the flag.
* Returns `false` when the contract has no entry ([has-announced-l1-early-exit](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L3328-L3338)).
* A non-2xx response throws an `Error` whose message starts with `Error calling read-only function.` and includes the status code and URL. If the node reports that the call failed, the `Error` message is the node's `cause`.

***

### Signature

```ts
function fetchHasAnnouncedL1EarlyExit(
  opts: { bondIndex: number; staker: string } & NetworkClientParam
): Promise<boolean>;
```

`opts` is a [NetworkClientParam](/reference/stacks.js/stacks-network/network/networkclientparam.md) plus `bondIndex` and `staker`.

***

### Returns

`Promise<boolean>`

Resolves to `true` if the staker has announced an L1 early exit for the bond.

***

### Parameters

#### opts.bondIndex (required)

* **Type**: `number`

Protocol bond index.

#### opts.staker (required)

* **Type**: `string`

Stacks address of the staker.

#### opts.network (optional)

* **Type**: `StacksNetworkName | StacksNetwork`

The network to query: a name such as `'mainnet'` or `'testnet'`, or a [StacksNetwork](/reference/stacks.js/stacks-network/network/stacksnetwork.md) object. Defaults to `'mainnet'`.

#### opts.client (optional)

* **Type**: `{ baseUrl?: string; fetch?: FetchFn }`

Overrides the API base URL or the `fetch` function, for example to query your own node. Fields you set replace the network's defaults.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.stacks.co/reference/stacks.js/stacks-bitcoin-staking/fetch/fetchhasannouncedl1earlyexit.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
