API Mastery: Understand, Create and Monetize Your Own API

Scale and balance your API infrastructure by expanding capacity and distributing requests to multiple servers, ensuring high availability, reduced latency, and resilience through horizontal scaling and load balancing.

Explore restful design principles for building scalable, maintainable APIs. Identify resources via URIs and manipulate them with standard HTTP methods in stateless requests, using representations like JSON, XML, or HTML.

Learn why API versioning matters and how to implement URL, header, media type, and semantic versioning, ensuring backward compatibility while evolving features with clear documentation and migration guides.

Explore rapid api's marketplace to identify a sellable idea by examining popular APIs, stars, subscribers, and latency. Add a twist to existing ideas and set up for creation and monetization.

Set up a new API from scratch using Express and Cheerio for web scraping, deploy publicly with Netlify, and publish and monetize your API on Rapid API.

Create your own api locally by cloning a repository, installing node and packages like express, axios, and cheerio, then deploy on netlify and publish on rapid api.

Deploy your built API live for free using Netlify's starter plan and GitHub deployment, then publish it on Rapid API for sale to reach users online.

Identify common api security vulnerabilities, such as sql injection, csrf, broken authentication, and insecure deserialization. Apply prevention strategies like parameterized queries, input validation, anti-csrf tokens, authentication, encryption, and testing.

Learn rate limiting and throttling to protect APIs, implement token bucket, fixed window, and leaky bucket strategies, and apply policy documentation, retries, monitoring, and role-based limits.

Web services enable interoperable machine-to-machine communication across networks. Explore soap, rest, and json/xml web services, the http transport, and their role in microservices, mobile apps, and IoT.

Understand three-digit http status codes, from 1xx informational to 5xx server errors, and learn examples like 200 ok, 301 moved permanently, 404 not found, and 500 internal server error.

Troubleshoot and debug http requests with a systematic approach, inspecting status codes, headers, payloads, and server logs using browser dev tools. Leverage Postman, curl, Fiddler, and Wireshark for effective debugging.

Explore request headers and query parameters, their role in authentication, content negotiation, caching, and rate limiting, and learn best practices for secure tokens, validation, and documentation.

Explore the OpenAPI specification, formerly swagger, a rest API description format used to design and document endpoints, operations, parameters, authentication, and formats in YAML or JSON.

Explore how to document an API with the Open API specification using Swagger Hub, focusing on the info metadata, server base URL, and tag organization for grouped endpoints.

Explore open api schemas in swagger hub by defining data models with yaml-based schemas, using types, enums, dictionaries and validation rules to model api endpoints.

Learn how soap APIs enable cross-platform communication via XML, perform CRUD operations, and be used with languages like JavaScript, Python, and C#. Understand envelope, header, body, and fault structures.

Understand JSON as a lightweight, language independent data format from JavaScript object notation, ideal for exchanging text data between browser and server using objects and arrays in APIs.

Compare XML and JSON for API data exchange, highlighting their structured, self-describing nature, and reveal differences in parsing ease, comments, and browser support.

Explore practical API calls by requesting endpoints with curl or Postman, learn how endpoints behave like links, and set up curl via package managers or downloads.
