## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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

## US National Debt Tracker — Treasury Fiscal Data

Get the daily US national debt — debt held by the public,
intragovernmental holdings, and total debt outstanding — with
day-over-day change, straight from the official [US Treasury Fiscal
Data API](https://fiscaldata.treasury.gov/).

Built for finance, macro, and policy research teams tracking the debt
trend without pulling Treasury's own CSV/XML exports.

### Input

```json
{
  "daysBack": 30,
  "maxResults": 30
}
```

| Field | Type | Description |
|---|---|---|
| `daysBack` | number | How many of the most recent daily records to return, counting back from today. Treasury publishes on business days only. Default `30`, max `1825` (~5 years). |
| `maxResults` | number | Maximum number of daily records to return. Default `30`, max `100`. |

### Output

One record per business day, newest first:

```json
{
  "date": "2026-08-14",
  "debtHeldByPublicUsd": 32200393497585.51,
  "intragovernmentalHoldingsUsd": 7733240968527.27,
  "totalDebtUsd": 39933634466112.78,
  "dayOverDayChangeUsd": -1181741731.59
}
```

`dayOverDayChangeUsd` is the change in total debt versus the prior
business day in the same result set (`null` for the oldest record
returned, since there's nothing earlier to compare against in that
batch).

### How it works

Direct calls to the official [US Treasury Fiscal Data
API](https://fiscaldata.treasury.gov/datasets/debt-to-the-penny/debt-to-the-penny)
(`Debt to the Penny` dataset) — no proxy, no key, no scraping. Public
US government data, updated each business day.

### Pricing note

Billed per **lookup** (one run), not per record returned — one charge
whether you request 1 day or 100.

# 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("m_ctim/us-national-debt-tracker").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("m_ctim/us-national-debt-tracker").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 m_ctim/us-national-debt-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,m_ctim/us-national-debt-tracker"
        }
    }
}

```

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).
