How to Integrate SHIBOR 3-Month Data into Your App: Complete API Guide
In the rapidly evolving world of fintech, access to accurate and timely financial data is crucial for developers, economists, and analysts. One such vital data point is the Shanghai Interbank Offered Rate (SHIBOR), particularly the 3-month rate (SHIBOR_3M). This guide will walk you through integrating SHIBOR 3-month data into your application using the Interest Rates API from interestratesapi.com. We will cover all necessary endpoints, provide code examples, and discuss best practices for implementation.
Understanding the Importance of SHIBOR 3-Month Data
SHIBOR is a critical benchmark for interbank lending rates in China, reflecting the cost of borrowing funds in the Chinese yuan (CNY) for a three-month period. This data is essential for various financial applications, including loan pricing, risk management, and economic analysis. By integrating SHIBOR_3M data, developers can enhance their applications with real-time financial insights, enabling better decision-making and improved user experiences.
Getting Started with the Interest Rates API
The Interest Rates API provides a straightforward way to access various interest rate data, including SHIBOR_3M. To begin, you will need to familiarize yourself with the API's endpoints and authentication method. All requests to the API must use the GET method, and authentication is handled via the api_key query parameter.
Available Endpoints
The Interest Rates API offers several endpoints that you can use to access SHIBOR_3M data:
/api/v1/symbols- Retrieve a catalogue of available rate symbols./api/v1/latest- Get the latest value for specified symbols./api/v1/historical- Fetch the value of a symbol on a specific date./api/v1/timeseries- Access a series of values between two dates./api/v1/fluctuation- Get change statistics over a specified range./api/v1/ohlc- Retrieve OHLC candlestick data./api/v1/convert- Compare loan interest costs between two rates.
Step-by-Step Integration Guide
1. Fetch Available Symbols
The first step in integrating SHIBOR_3M data is to retrieve the available symbols from the API. This can be done using the /api/v1/symbols endpoint.
Here’s how to make the request:
curl "https://interestratesapi.com/api/v1/symbols?category=interbank&base=CNY&api_key=YOUR_KEY"JSON response example:
{
"success": true,
"count": 1,
"symbols": [
{
"symbol": "SHIBOR_3M",
"name": "SHIBOR 3-Month Rate",
"category": "interbank",
"country_code": "CN",
"currency_code": "CNY",
"frequency": "monthly",
"description": "The interest rate at which banks lend to each other for a three-month period."
}
]
}
2. Retrieve the Latest SHIBOR 3-Month Rate
Once you have confirmed the availability of the SHIBOR_3M symbol, you can retrieve the latest rate using the /api/v1/latest endpoint.
Example request:
curl "https://interestratesapi.com/api/v1/latest?symbols=SHIBOR_3M&api_key=YOUR_KEY"JSON response example:

"rates": {
"SHIBOR_3M": 5.30
},
"currencies": {
"SHIBOR_3M": "CNY"
}
}
4. Retrieve Time Series Data
For a broader analysis, you can access a time series of SHIBOR_3M rates between two dates using the /api/v1/timeseries endpoint.
Example request:
curl "https://interestratesapi.com/api/v1/timeseries?start=2025-07-21&end=2026-07-21&symbols=SHIBOR_3M&api_key=YOUR_KEY"JSON response example:

"rates": {
"SHIBOR_3M": {
"2025-07-21": 5.50,
"2025-07-22": 5.45,
"2025-07-23": 5.40
}
},
"frequencies": {
"SHIBOR_3M": "daily"
},
"currencies": {
"SHIBOR_3M": "CNY"
}
}
5. Analyze Fluctuations
To understand how the SHIBOR_3M rate has changed over a period, use the /api/v1/fluctuation endpoint.
Example request:
curl "https://interestratesapi.com/api/v1/fluctuation?start=2025-07-21&end=2026-07-21&symbols=SHIBOR_3M&api_key=YOUR_KEY"JSON response example:
{
"success": true,
"rates": {
"SHIBOR_3M": {
"start_date": "2025-07-21",
"end_date": "2026-07-21",
"start_value": 5.50,
"end_value": 5.33,
"change": -0.17,
"change_pct": -3.09,
"high": 5.50,
"low": 5.25
}
}
}
6. Retrieve OHLC Data
If you need candlestick data for SHIBOR_3M, use the /api/v1/ohlc endpoint. This is useful for visualizing trends over time.
Example request:
curl "https://interestratesapi.com/api/v1/ohlc?symbols=SHIBOR_3M&period=monthly&start=2025-07-21&end=2026-07-21&api_key=YOUR_KEY"JSON response example:

"data_points": 30
}
]
}
}
7. Compare Loan Interest Costs
Finally, you can compare the interest costs of loans using the /api/v1/convert endpoint. This is particularly useful for financial analysis and decision-making.
Example request:
curl "https://interestratesapi.com/api/v1/convert?from=SHIBOR_3M&to=ECB_MRO&amount=100000&term_months=12&api_key=YOUR_KEY"JSON response example:

}
Error Handling and Rate Limits
When working with the Interest Rates API, it's essential to handle errors gracefully. Common error responses include:
- 401: Missing or invalid
api_key. - 403: Account without an active plan.
- 404: No symbols matched or no data for the requested date/range.
- 422: Validation error (e.g., wrong date format, invalid symbol).
- 429: Request quota exhausted.
For rate limits, the API provides the following headers:
- X-RateLimit-Limit: The maximum number of requests allowed in a given time period.
- X-RateLimit-Remaining: The number of requests remaining in the current time window.
- X-RateLimit-Reset: The time when the rate limit will reset.
Mini Project: Node.js/Express Endpoint
To demonstrate the integration of SHIBOR_3M data, here’s a simple Node.js/Express endpoint that fetches and serves the latest SHIBOR_3M rate:
const express = require('express');
const fetch = require('node-fetch');
const app = express();
const PORT = process.env.PORT || 3000;
app.get('/shibor', async (req, res) => {
const apiKey = 'YOUR_KEY';
const response = await fetch(`https://interestratesapi.com/api/v1/latest?symbols=SHIBOR_3M&api_key=${apiKey}`);
const data = await response.json();
res.json(data);
});
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
This endpoint fetches the latest SHIBOR_3M rate and serves it as a JSON response. Make sure to replace YOUR_KEY with your actual API key.
Conclusion
Integrating SHIBOR 3-month data into your application using the Interest Rates API from interestratesapi.com is a straightforward process that can significantly enhance your financial applications.
