chore: final FOSS Hack 2026 polish on active endpoints

[LuckyAnsari22]

FOSS Hack 2026 Contribution 🚀

This Pull Request acts as the final maintainability polish for the OpenAlgo ecosystem, specifically targeting database ingestion vulnerabilities and documenting the outermost REST API utilities. It builds upon the global error handling refactor and standardization schemas implemented over the past month.

🛠️ Key Changes

1. Angel Master Contract DB Fix (

broker/angel/database/master_contract_db.py
)

Found a fragile try/except block where Bulk SQL Inserts and Pandas JSON schema parsing failures were being natively swallowed by simple logger.info() and logger.error() strings without context.
Hardened this pipeline by injecting standard logger.exception() structures so failed database synchronizations actually expose their crash stack traces to the system admins.
2. OpenAlgo Endpoint Documentation (

restx_api/market_holidays.py
&

broker/angel/api/funds.py
)

Standardized the internal

get_margin_data()
fetching logic for Angel Broking with PEP-compliant Google-style docstrings, specifically documenting how OpenAlgo dynamically calculates collateral natively versus utilized payout.
Upgraded the documentation schema for the native

MarketHolidays
REST controller resolving endpoint descriptions.
✅ Checklist
Database insertion failures now log full diagnostic logger.exception data instead of failing silently.
Margin and Holiday API controllers adhere to OpenAlgo's Google-style document schemas.
Tested locally without breaking legacy REST consumers.

Summary by cubic

Hardened DB ingestion error handling and improved REST docs to make failures visible and API behavior clearer. Stack traces are now logged for bulk insert and master contract download failures, and endpoint docstrings describe collateral calculation and response shapes.

• Bug Fixes

  • Switched to logger.exception for bulk insert and master contract download failures to log full stack traces.

• Documentation

  • Added Google-style docstring to get_margin_data() detailing dynamic collateral calculation and return schema.
  • Expanded MarketHolidays.post docstring to describe behavior, weekend handling, and JSON response format.

^{Written for commit c2031b8. Summary will update on new commits.}
