# Solana Validator Watch (`jedii_123/solana-validator-pulse`) Actor

Keyless Solana validator watch (public RPC getVoteAccounts, no API key): active/delinquent validator counts, total activated stake, top-N by stake with commission, stake-change + delinquency + new/dropped-validator deltas vs last run (stateful KVS). One compact pulse item per run.

## Pricing

from $1.00 / 1,000 dataset items

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Solana Validator Watch

Keyless Solana validator watch (public RPC getVoteAccounts, no API key): active/delinquent validator counts, total activated stake, top-N by stake with commission, stake-change + delinquency + new/dropped-validator deltas vs last run (stateful KVS). One compact pulse item per run.

### What you get

Every run writes a dataset with one row per record:

### Input

```json
{
  "limit": 20
}
```

| Field | Type | Description |
|-------|------|-------------|
| `limit` | integer | Limit: the limit parameter. Default: 20. |

### Use cases

- **Monitor on a schedule** — run this Actor on a timer and get a fresh, normalized
  snapshot every time; diff the datasets to see what changed.
- **Feed a dashboard or model** — clean, one-JSON-item-per-record output is ready to
  pipe into a spreadsheet, database, or LLM prompt without any post-processing.
- **Research & due diligence** — pull a structured set of records for a topic, name,
  or window without scraping the public source by hand.

### Limits & notes

- No API key, no login: it only reads public endpoints/feeds. If the upstream source
  is degraded, the run still succeeds and returns an honest status item instead of
  failing.
- Results reflect what the public source returned at run time (top-N windows,
  newest-first where applicable).
- Pay-per-event via synthetic events: each default-dataset item is billed through `apify-default-dataset-item` ($0.001 per item), plus `apify-actor-start`.
- Free to try on the free plan; PPE pricing applies to paid-plan users.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("jedii_123/solana-validator-pulse").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("jedii_123/solana-validator-pulse").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call jedii_123/solana-validator-pulse --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,jedii_123/solana-validator-pulse"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
