Api Only

What this skill does

Api Only provides a simple REST API for managing notes, enabling backend-only operations without a frontend interface. It supports full CRUD functionality with endpoints to create, read, update, and delete notes, returning structured JSON responses including fields like id, title, content, and timestamps. The API includes input validation, proper HTTP status codes, and error handling to maintain reliable interactions.

Who it's for

This skill is designed for developers and backend engineers who need a lightweight notes API for internal tools, prototypes, or testing backend workflows. It fits scenarios where frontend complexity is unnecessary or handled separately, such as agencies building custom integrations, growth teams automating note management, or performance marketers tracking campaign annotations in backend systems.

Key workflows

A typical workflow starts by creating a note via the POST endpoint with a title and content, receiving confirmation with a unique id and creation timestamp. Users then retrieve notes through GET requests either as a full list or individually by id, allowing for easy synchronization or display elsewhere. Updates happen through PUT requests to modify note content or titles while preserving metadata, and notes can be removed through DELETE calls. Additionally, health checks verify API availability and latency for monitoring.

Common questions

How do you handle missing or invalid data on creation? The API returns a 400 status with a JSON error response when validation fails, ensuring only valid notes are stored. Can I retrieve a note that doesn’t exist? Requests for nonexistent note ids return a 404 error, signaling missing resources clearly. Is authentication required? This API does not include authentication or rate limiting, focusing solely on core note management functions.

How to use in Metaflow

Attach the Api Only skill to a Metaflow agent task to enable backend note management through REST calls within your flow. Expect endpoint responses that facilitate creating, updating, and deleting notes programmatically, with consistent JSON structures for easy parsing. This skill works well when you need a minimal backend service to support note-related data without adding frontend dependencies or complexity.
