## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## US Treasury Yield Curve Tracker

> Daily US Treasury par yield curve straight from **treasury.gov**: all tenors 1M–30Y, plus **2s10s / 3m10y / 5s30s** spreads (bps) and inversion flags. Macro recession indicator. **No API key.**

---

### Why this exists

The 2s10s spread (10Y yield minus 2Y yield) is the single most-watched recession indicator in finance. **Every US recession since 1955 has been preceded by a 2s10s inversion.**

The data is free and public — but it's published as a PDF and a clunky XML feed. This actor:
- Pulls the raw CSV from treasury.gov
- Computes 2s10s, 3m10y, 5s30s spreads (bps) automatically
- Flags inversion (negative spread) per row
- Configurable lookback (default 60 business days)
- Telegram alerts on inversion or spread threshold

---

### What you get per row

| Field | Example | Notes |
|---|---|---|
| `date` | `06/09/2026` | business day |
| `yield_3m_pct` | `3.79` | |
| `yield_2y_pct` | `4.13` | |
| `yield_5y_pct` | `4.26` | |
| `yield_10y_pct` | `4.53` | |
| `yield_30y_pct` | `5.01` | |
| `spread_2s10s_bps` | `+40` | classic recession gauge |
| `spread_3m10y_bps` | `+74` | Fed-preferred gauge |
| `spread_5s30s_bps` | `+75` | long-end steepness |
| `inverted_2s10s` | `false` | true when negative |
| `inverted_3m10y` | `false` | |

Plus full curve: 1M / 1.5M / 2M / 4M / 6M / 1Y / 3Y / 7Y / 20Y.

---

### Use cases

1. **Recession signal** — Alert the moment 2s10s flips negative
2. **Backtest macro strategies** — 60+ days of daily curve in one run
3. **Bond research** — Build a research note with snapshot of full curve
4. **Cross-asset** — Combine with crypto data to see real-yield → BTC correlation
5. **Risk dashboard** — Daily snapshot in a CSV/Sheets/Slack for the team

### Quick start

#### Default — last 60 business days of 2026 curve
```json
{}

#### Full year history

```json
{
  "year": 2026,

```json
{
  "alertOnInversion": true,
  "telegramBotToken": "YOUR_BOT_TOKEN",
  "telegramChatId": "YOUR_CHAT_ID"
}
```

#### Alert when 2s10s drops below 10bps (near-inversion)

```json
{
  "alert2s10sBelowBps": 10,
  "telegramBotToken": "YOUR_BOT_TOKEN",
  "telegramChatId": "YOUR_CHAT_ID"
}
