Fix incorrect Redis Cloud API endpoint documentation

[joshrotenberg]

Problem

During testing of the Redis Cloud API quick start guide, we discovered several incorrect endpoint references in the documentation and potentially in the code:

1. Account Endpoint Issue

• Documented as: /account
• Actually is: / (root endpoint)
• The account information is retrieved from the root endpoint, not /account
• Test confirmed: redisctl api cloud get / returns account info with fields like account.id and account.name

2. Database Stats/Metrics Endpoints Don't Exist

• Documented as:
  • /subscriptions/{id}/databases/{db_id}/stats
  • /subscriptions/{id}/databases/{db_id}/stats/last
  • /subscriptions/{id}/databases/{db_id}/metrics
  • /subscriptions/{id}/databases/{db_id}/metrics/last
• Reality: These endpoints return 404 errors
• Actual metrics location: Metrics data is included directly in the database details response from /subscriptions/{id}/databases/{db_id}
  • Fields include: memoryUsedInMb, datasetSizeInGb, memoryLimitInGb, throughputMeasurement

Affected Files to Check

Based on grep results, these files may contain incorrect references:

• docs/src/common-features/raw-api.md
• docs/src/developer/libraries.md
• Any Cloud API handler code that references these endpoints
• Test files that mock these endpoints

Action Items

• Search for all references to /account endpoint in Cloud API context
• Search for all references to database stats/metrics endpoints
• Update documentation to use correct endpoints
• Update any code that references these incorrect endpoints
• Update tests if they mock these non-existent endpoints
• Verify no commands are trying to use these endpoints

Test Commands to Verify

# Correct - returns account info
redisctl api cloud get /

# Incorrect - would need to be fixed if referenced
redisctl api cloud get /account  # This doesn't exist

# Correct - database details include metrics
redisctl api cloud get /subscriptions/123/databases/456

# Incorrect - these return 404
redisctl api cloud get /subscriptions/123/databases/456/stats
redisctl api cloud get /subscriptions/123/databases/456/stats/last
