## 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

## CMS Medicare Part B Drug Spending Scraper API

Search CMS's official 2024 Medicare Part B Spending by Drug dataset by brand, generic name, HCPCS, manufacturer where reported, annual spending, beneficiaries, claims, dosage units, average costs, and growth.

Empty input returns one verified **Keytruda / J9271** record with a normalized 2020-2024 annual series. Maximum first-run charge: **$0.0021** ($0.0001 start + $0.002/item).

```json
{}
```

```json
{"genericName":"Pembrolizumab","year":2024,"minTotalSpending":1000000000,"maxResults":10}
```

Output preserves raw CMS fields while normalizing changing year-suffixed columns into bounded `annualMetrics`, calculates annual growth, retains blanks/suppressed values as null, and discloses candidate/page/year/result bounds, source vintage, retrieval time, and source URLs.

CMS Part B spending is lagged aggregate claims/program evidence—not list price, rebate/net cost, prescribing advice, efficacy, safety, current market share, endorsement, or a complete/current utilization view. A bounded no-match does not prove absence.

# Actor input Schema

## `brandName` (type: `string`):

Exact CMS brand name, such as Keytruda.

## `genericName` (type: `string`):

Exact CMS generic name, such as Pembrolizumab.

## `hcpcsCode` (type: `string`):

Exact five-character HCPCS code, such as J9271.

## `manufacturer` (type: `string`):

Local case-insensitive manufacturer filter when a CMS row exposes a manufacturer field. The current Keytruda row does not include one.

## `year` (type: `integer`):

Return and apply thresholds to one annual metric year. Leave 0 for the latest available year.

## `minTotalSpending` (type: `number`):

Optional minimum total spending (usd) filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minBeneficiaries` (type: `integer`):

Optional minimum beneficiaries filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minClaims` (type: `integer`):

Optional minimum claims filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minDosageUnits` (type: `number`):

Optional minimum dosage units filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minAverageSpendingPerUnit` (type: `number`):

Optional minimum average spending per dosage unit filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minAverageSpendingPerBeneficiary` (type: `number`):

Optional minimum average spending per beneficiary filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `minSpendingGrowth` (type: `number`):

Decimal year-over-year rate; 0.10 means 10%. Applied to the selected/latest year.

## `sortBy` (type: `string`):

Optional sort by filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `sortDirection` (type: `string`):

Optional sort direction filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `maxCandidates` (type: `integer`):

Total source rows checked across all pages before local thresholds and sorting.

## `maxPages` (type: `integer`):

Optional maximum cms pages filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `maxAnnualSeriesLength` (type: `integer`):

Optional maximum annual observations per drug filter or result-control setting. See the README for exact source semantics, bounds, and examples.

## `maxResults` (type: `integer`):

Total paid output records after filters. The default is one record for a maximum first-run charge of $0.0021 including start.

## `maxTotalChargeUsd` (type: `number`):

Optional ceiling used to reduce maxResults before querying at $0.002 per output item.

## JavaScript example

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

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("pink_comic/cms-part-b-drug-spending").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();

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("pink_comic/cms-part-b-drug-spending").call(run_input=run_input)

## CLI example

```bash
echo '{}' |
apify call pink_comic/cms-part-b-drug-spending --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,pink_comic/cms-part-b-drug-spending"
        }
    }
}

```

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).
