## Structure and components

- [low] MongoDB's deprecation page includes tutorials for building custom API layers using Express.js, FastAPI, Spring Boot, and serverless functions such as AWS Lambda and Azure Functions.

## Problems, failure modes and limitations

- [low] MongoDB deprecated the Atlas Data API, an HTTP-based CRUD interface for interacting with MongoDB collections over HTTPS without database drivers, as part of the broader shutdown of Atlas App Services, with the end-of-life date of September 30, 2025 having passed. (verified as of 2026-10-15) Sources: https://blog.dreamfactory.com/the-best-atlas-data-api-alternatives-in-2026-a-complete-comparison — source: `~/.global-ai-hub/research/.pipeline/mongodb-2026-10-14/frb/atlas-data-api-eol-703ee9ca93/rabbithole-synthesis.md#core`
- [low] Using drop-in replacements for the Atlas Data API involves adopting the same deprecated API design patterns, including POST-for-everything and non-standard REST conventions.

## Facts and statements

- [low] The Atlas Data API served key use cases including serverless and edge environments like Cloudflare Workers and AWS Lambda, low-code and no-code integrations such as Azure Logic Apps, Zapier, and Retool, mobile apps, and IoT devices.

- [low] Delbridge Data API mimics the Atlas Data API format to minimize client code changes, supporting full CRUD operations, native MQL, EJSON compatibility, and bulk operations, requiring only updates to the endpoint URL and authentication logic for migration.

- [low] FerretDB v2, released in February 2025, includes a Data API that directly replaces the Atlas Data API HTTP interface.

- [low] Migrating to DreamFactory requires updating client code from Atlas Data API POST requests (e.g., /action/find) to DreamFactory's standard REST conventions (GET /api/v2/mongodb/_table/collection).
