## 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.

## 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.**

### ⚡ Run in 30 seconds

Click **Start** with default settings — fetches today's full Treasury yield curve (1M through 30Y) directly from treasury.gov, plus the 2s10s, 3m10y, and 5s30s spreads with inversion flags. No API key needed.

***

### Input Parameters

| Parameter | Type | Default | Description |
|---|---|---|---|
| `year` | integer | `2026` | Calendar year to pull (uses current year if omitted). |
| `daysBack` | integer | `60` | Return at most this many most recent business days. 0 = no l |
| `sortBy` | string | `date_desc` | Row order in output. |
| `alertOnInversion` | boolean | `False` | Send Telegram alert if the latest 2s10s OR 3m10y spread is n |
| `alert2s10sBelowBps` | number | `0` | Telegram alert when latest 2s10s ≤ this value (bps). 0 = dis |
| `telegramBotToken` | string | `—` | Telegram bot token. |
| `telegramChatId` | string | \`\` | Telegram chat ID to send alerts to (get it from @userinfobot |

***

### 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.
