## 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

## Yield-Bearing Stablecoin Tracker

> Compares APY and TVL across major yield-bearing stablecoins: sUSDe, sUSDS, sDAI, sGHO, sfrxUSD vs benchmark USDC lending rates. Ranks by net yield with spread-to-USDC in basis points. No API key required.

***

### What It Does

Aggregates yield-bearing stablecoin data from Ethena's native API and DefiLlama:

| Token | Protocol | Mechanism | Data Source |
|-------|----------|-----------|-------------|
| sUSDe | Ethena | Delta-neutral perp funding | Ethena API (native — most accurate) |
| sUSDS | Sky (MakerDAO) | DSR-backed | DefiLlama |
| sDAI | MakerDAO | DSR (old flavor) | DefiLlama |
| sGHO | Aave | Revenue sharing | DefiLlama |
| sfrxUSD | Frax | ETH staking + fees | DefiLlama |

**Output includes:**

- Current APY for each token
- sUSDe historical averages (30d, 90d, all-time from Ethena)
- Benchmark USDC lending rate (Aave v3 average)
- `spread_vs_usdc_bps` — extra yield vs risk-free reference in basis points
- USDe peg health: price, circulating supply, deviation in bps
- Tokens ranked by APY descending

***

### Why It's Useful

Yield-bearing stablecoins are the "savings accounts" of DeFi. This actor helps you:

- Find the highest safe yield on stablecoins
- Detect when sUSDe yield compresses below market rates (funding rate bear market)
- Monitor USDe peg health as an early warning for Ethena stress

***

### Pricing

**$0.01 flat per run.**

# Actor input Schema

## `minTvlUsdM` (type: `integer`):

Minimum TVL in millions USD to include a pool (filters out tiny/illiquid pools).

## Actor input object example

```json
{
  "minTvlUsdM": 10
}
```

# 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("gochujang/yield-bearing-stablecoin-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("gochujang/yield-bearing-stablecoin-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 gochujang/yield-bearing-stablecoin-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,gochujang/yield-bearing-stablecoin-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).
