## 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?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Blast L2 Pulse

Keyless Blast L2 (chain 81457, Arbitrum Orbit, 100x gas) network-health pulse (public JSON-RPC, no API key): latest block number + timestamp, live gas price (GWEI), chain-id gate check, and a stateful diff vs the previous run (tip delta + gas drift). One item per run. Read-only.

### What you get

Every run writes a dataset with one row per record:

```json
{
  "chain": "blast",
  "chainId": 81457,
  "tipBlock": 39796405,
  "tipTs": "2026-09-03T02:30:25Z",
  "gasPriceGwei": 0.001,
  "prevTipBlock": null,
  "gasPriceDeltaPct": null,
  "chainIdVerified": true,
  "summary": "first run (baseline); gas 0.001 GWEI; chain id 81457 verified",
  "ts": "2026-09-03T02:30:25Z"
}
```

### Input

```json
{
  "host": "https://rpc.blast.io"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `host` | string | Host: the host parameter. Default: "https://rpc.blast.io". |

### 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 = {
    "host": "https://rpc.blast.io"
};

// Run the Actor and wait for it to finish
const run = await client.actor("jedii_123/blast-l2-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 = { "host": "https://rpc.blast.io" }

# Run the Actor and wait for it to finish
run = client.actor("jedii_123/blast-l2-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 '{
  "host": "https://rpc.blast.io"
}' |
apify call jedii_123/blast-l2-pulse --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,jedii_123/blast-l2-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).
