# Monitor

> Track monitored accounts with Custom Signals.

Monitor is the account tracking side of Plyne.

Your team adds monitored accounts and defines Custom Signals in plain language, such as whether a company is hiring for a role, expanding into a new location, filing a disclosure, or adopting a specific tool.

Plyne checks those accounts on a schedule and surfaces account signals worth acting on.

## Endpoints

```http theme={null}
POST /v1/monitor/accounts
POST /v1/monitor/signals
POST /v1/monitor/custom-signals
```

Use `accounts` for the current monitored account queue, `signals` for observation history, and `custom-signals` to list the definitions available for filtering.

## Filters

Most Monitor reads use body filters:

```json theme={null}
{
  "account_ids": ["d8companyid"],
  "signals": ["d8signaldefinitionid"],
  "statuses": ["detected"],
  "cursor": { "limit": 50 }
}
```

Omit a filter to read across all monitored accounts or all Custom Signals in your organization.
