+When working with JSON data, you may encounter issues such as trailing commas, mismatched braces, or incorrect data types that make the JSON invalid. {% data variables.product.prodname_copilot_chat %} can help you debug and fix these errors by suggesting corrections to fix invalid JSON.
+
+## Example scenario
+
+Consider a scenario where an application consumes JSON data from an API, but the response fails to parse due to invalid formatting. You receive the error message:
+
+```bash
+Error: Parse error
+----------------------^
+Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
+```
+
+Below is the JSON data that caused the error:
+
+```json
+{
+  "location": "San Francisco",
+  "current_weather": {
+    "temperature": 18,
+    "unit": "Celsius",
+    "conditions": "Cloudy
+  },
+  "forecast": {
+    "day": "Monday",
+    "high": 22,
+    "low": 15,
+    "precipitation": 10
+  }
+}
+```
+
+## Example prompt
+
+```Why is my JSON object invalid and how can I fix it?```
+
+## Example response
+
+{% data reusables.copilot.example-prompts.response-is-an-example %}
+
+{% data variables.product.prodname_copilot_short %} might suggest that your JSON is invalid because it is missing a closing quote for the `conditions` value. Here is the corrected JSON:
+
+```json
+{
+  "location": "San Francisco",
+  "current_weather": {
+    "temperature": 18,
+    "unit": "Celsius",
+    "conditions": "Cloudy"
+  },
+  "forecast": {
+    "day": "Monday",
+    "high": 22,
+    "low": 15,
+    "precipitation": 10
+  }
+}
+```
+
+In this example response, {% data variables.product.prodname_copilot_short %}'s suggestions include fixing the closing quote for the `conditions` value, which resolves the JSON parsing error.

+title: Handling API rate limits
+shortTitle: Handle API rate limits
+intro: '{% data variables.product.prodname_copilot_chat_short %} can help handle API  rate limits by suggesting code that detects implements retry logic.'
+versions:
+  feature: copilot
+category:

+topics:

+---
+
+When making requests to APIs, it's common to encounter rate limits that restrict the number of calls you can make within a certain time frame. {% data variables.product.prodname_copilot_chat %} can help you handle these limits by suggesting code to detect rate limit responses and automatically retry requests after a delay.
+
+## Example scenario
+
+The following Python code fetches weather data from an external API. If the API has rate limits, requests may fail when limits are exceeded, and your app may need a way to handle these responses gracefully by implementing retry logic.
+
+```python
+from flask import Flask, request
+import requests
+
+app = Flask(__name__)
+
+WEATHER_API_URL = "https://api.example.com/weather"
+
+@app.route('/get_weather', methods=['GET'])
+def get_weather():
+    city = request.args.get('city')
+    # Simulate an API request to the external weather service
+    response = requests.get(WEATHER_API_URL, params={"city": city})
+    weather_data = response.json() 
+
+    return weather_data
+```
+
+## Example prompt
+
+`How can I handle API rate limits within get_weather().`
+
+## Example response
+
+{% data reusables.copilot.example-prompts.response-is-an-example %}
+
+{% data variables.product.prodname_copilot_short %} might suggest code that implements a retry mechanism with exponential backoff to limit the frequency of retry attempts.
+
+For example:
+
+```python
+import requests
+from flask import Flask, request
+from requests.adapters import HTTPAdapter
+from requests.packages.urllib3.util.retry import Retry
+
+app = Flask(__name__)
+
+WEATHER_API_URL = "https://api.example.com/weather"
+
+def requests_retry_session(
+    retries=3,
+    backoff_factor=0.3,
+    status_forcelist=(500, 502, 504),
+    session=None,
+):
+    session = session or requests.Session()
+    retry = Retry(
+        total=retries,
+        read=retries,
+        connect=retries,
+        backoff_factor=backoff_factor,
+        status_forcelist=status_forcelist,
+    )
+    adapter = HTTPAdapter(max_retries=retry)
+    session.mount("http://", adapter)
+    session.mount("https://", adapter)
+    return session
+
+@app.route('/get_weather', methods=['GET'])
+def get_weather():
+    city = request.args.get('city')
+    try:
+        response = requests_retry_session().get(WEATHER_API_URL, params={"city": city})
+        response.raise_for_status()
+        weather_data = response.json()
+    except requests.exceptions.RequestException as e:
+        return {"error": str(e)}, 500
+
+    return weather_data
+```
+
+In this example, {% data variables.product.prodname_copilot_short %}'s suggestions include setting up a retry session that allows the code to automatically retry requests if they fail due to specific status codes (500, 502, 504). The `backoff_factor` gradually increases the delay between retries, helping avoid exceeding the API's rate limit further.

+Working with legacy code can be challenging for developers, especially when the code is complex or not well-documented. In such cases, it can be helpful to use Copilot Chat to explain unclear or complex code to other developers or to document it for future reference.
+
+## Example scenario
+
+The block of COBOL below connects to a database and inserts a record. The code lacks documentation, which makes it difficult to understand what it does and how it works.
+
+```text
+IDENTIFICATION DIVISION.
+PROGRAM-ID. INSERT-RECORD.
+
+ENVIRONMENT DIVISION.
+
+DATA DIVISION.
+WORKING-STORAGE SECTION.
+01  WS-STATUS-FLAGS.
+    05 WS-DB-STATUS     PIC X(2).
+       88 WS-SUCCESS    VALUE "00".
+    05 WS-SQLCODE       PIC S9(9) COMP.
+    05 WS-ERROR-MSG     PIC X(50).
+
+LINKAGE SECTION.
+01  LS-PARAMETERS.
+    05 LS-PERSON-RECORD.
+       10 PERSON-ID     PIC 9(6).
+       10 PERSON-NAME   PIC X(50).
+       10 PERSON-AGE    PIC 9(3).
+    05 LS-RESULT        PIC X.
+       88 SUCCESS       VALUE 'T'.
+       88 FAILED        VALUE 'F'.
+
+PROCEDURE DIVISION USING LS-PARAMETERS.
+    PERFORM INSERT-AND-VALIDATE
+    GOBACK
+    .
+
+INSERT-AND-VALIDATE.
+    EXEC SQL
+        INSERT INTO persons (id, name, age)
+        VALUES (:PERSON-ID, :PERSON-NAME, :PERSON-AGE)
+    END-EXEC
+
+    IF SQLCODE = 0
+        EXEC SQL COMMIT END-EXEC
+        SET SUCCESS TO TRUE
+    ELSE
+        EXEC SQL ROLLBACK END-EXEC
+        SET FAILED TO TRUE
+        STRING "DB Error: " SQLCODE 
+            DELIMITED BY SIZE 
+            INTO WS-ERROR-MSG
+        DISPLAY WS-ERROR-MSG
+    END-IF
+    .
+```
+
+## Example prompt
+
+We can use a simple prompt to ask {% data variables.product.prodname_copilot_chat_short %} to document the code.
+
+`Document this code`
+
+> [!NOTE] If you want the documentation generated in another format like Markdown, you can specify the desired output format in the prompt. For example: `Document this code in Markdown`.
+
+## Example response

+{% data reusables.copilot.example-prompts.response-is-an-example %}
