+## Overview
+
+This guide shows how to programmatically access usage-related analytics through the **Codefresh Analytics API**. You'll learn the key endpoints, available reports, supported query parameters, and see a script you can adapt for your own reporting needs.  
+
+> **Goal:** Pull usage metrics (e.g., credit consumption, pipeline credit consumption, active committers) for monitoring or reporting.
+
+## Prerequisites
+
+- A Codefresh **API key** with permission to access Analytics.
+- Date range values in `YYYY-MM-DD` format for queries.
+- Optional: `jq` for pretty-printing JSON responses when using shell examples.
+
+## Details
+
+### Endpoints
+
+**Reports**
+```
+GET https://g.codefresh.io/api/analytics/reports/{reportName}
+```
+Replace `{reportName}` with the specific report you want to query. Examples:
+```
+GET https://g.codefresh.io/api/analytics/reports/creditConsumption
+GET https://g.codefresh.io/api/analytics/reports/pipelineCreditConsumption
+GET https://g.codefresh.io/api/analytics/reports/activeCommiters
+```
+
+**Discover reports and parameters**
+```
+GET https://g.codefresh.io/api/analytics/metadata
+```
+
+> **Notes**
+> - Not all reports and query parameters are publicly documented.
+> - Different reports support different time ranges and granularities.
+> - Use the **metadata** endpoint to discover available reports and their parameters.
+
+### Query parameters & time dimensions
+
+**creditConsumption** and **pipelineCreditConsumption** support:  
+- **No granularity (aggregated):** 1 day – 1 year  
+  `?dateRange=YYYY-MM-DD&dateRange=YYYY-MM-DD`  
+- **Monthly granularity:** 1 day – 1 year  
+  `?granularity=month&dateRange=YYYY-MM-DD&dateRange=YYYY-MM-DD`  
+- **Daily granularity:** 2 days – 45 days  
+  `?granularity=day&dateRange=YYYY-MM-DD&dateRange=YYYY-MM-DD`  
+
+**activeCommiters** supports:  
+- **Monthly granularity:** 3 months – 1 year  
+  `?granularity=month&dateRange=YYYY-MM-DD&dateRange=YYYY-MM-DD`
+
+### Examples
+
+**Credit consumption (monthly)**
+```
+curl -s -H "Authorization: $API_KEY" "https://g.codefresh.io/api/analytics/reports/creditConsumption?granularity=month&dateRange=${START_DATE}&dateRange=${END_DATE}" | jq .
+```
+
+**Pipeline credit consumption (daily within 45 days)**
+```
+curl -s -H "Authorization: $API_KEY" "https://g.codefresh.io/api/analytics/reports/pipelineCreditConsumption?granularity=day&dateRange=${START_DATE}&dateRange=${END_DATE}" | jq .
+```
+
+**Active committers (monthly)**
+```
+curl -s -H "Authorization: $API_KEY" "https://g.codefresh.io/api/analytics/reports/activeCommiters?granularity=month&dateRange=${START_DATE}&dateRange=${END_DATE}" | jq .
+```
+
+### Suggested script
+
+```
+#!/bin/bash
+# Expects these env vars:
+#   API_KEY       -> Codefresh API key
+#   START_DATE    -> "YYYY-MM-DD"
+#   END_DATE      -> "YYYY-MM-DD"
+
+: "${API_KEY:?Set API_KEY}"
+: "${START_DATE:?Set START_DATE}"
+: "${END_DATE:?Set END_DATE}"
+
+# Example: fetch credit consumption (monthly)
+curl -s -H "Authorization: $API_KEY"   "https://g.codefresh.io/api/analytics/reports/creditConsumption?granularity=month&dateRange=${START_DATE}&dateRange=${END_DATE}"   | jq .
+# Adapt the endpoint for pipelineCreditConsumption or activeCommiters as needed.
+```
+
+## Best practices
+
+- Use the **metadata** endpoint to confirm available reports and supported query parameters.
+- Select a date range and **granularity** appropriate for your reporting needs.
+- Automate data collection (cron, pipeline) to regularly sync usage data into your BI/monitoring systems.
