# Getting Forward Rates

Use the /forward\_rate endpoint to retrieve an implied rate between any two future dates or tenors. For more details visit <https://www.bluegamma.io/interest-rate-api>

```python
url = "https://api.bluegamma.io/v1/forward_rate"
params = {
    "index": "SOFR",
    "start_date": "2025-06-01",
    "end_date": "2025-12-01"
}
response = requests.get(url, headers=headers, params=params)
print(response.json())
```

```bash
curl -X GET "https://api.bluegamma.io/v1/forward_rate?index=SOFR&start_date=2025-06-01&end_date=2025-12-01" \
  -H "x-api-key: your_api_key_here"
```

**📆 Example for a Historical Forward Rate**

Add the `valuation_time` parameter (ISO format, UTC) to get the forward rate as it would have been at a specific timestamp.

```python
params = {
    "index": "SOFR",
    "start_date": "2025-06-01",
    "end_date": "2025-12-01",
    "valuation_time": "2025-04-15T12:00:00Z"
}
```

```bash
curl -X GET "https://api.bluegamma.io/v1/forward_rate?index=SOFR&start_date=2025-06-01&end_date=2025-12-01&valuation_time=2025-04-15T12%3A00%3A00Z" \
  -H "x-api-key: your_api_key_here"
```

🧠 **Tips**

* `start_date` and `end_date` can be either tenors (`"6M"`, `"1Y"`) or full ISO dates (`"2025-06-01"`)
* `valuation_time` is optional — omit it for live data
* Historical requests return the rate *as it was known* at that point in time
