Topics include HTTP methods, REST, GraphQL, SOAP, gRPC, WebSockets, and Webhooks, with their respective trade-offs. Also covers how APIs power AI applications including calling AI models, giving models tool access, and orchestrating workflows. Introduces the Model Context Protocol (MCP) as a standard for AI tool connectivity. Covers API infrastructure concepts like API gateways, rate limiting, authentication, monitoring, and documentation. Ends with a brief overview of frameworks like Flask, FastAPI, Express.js, and Spring Boot, plus a pointer to a free Coursera project. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the difference between REST and GraphQL APIs? REST uses multiple fixed endpoints and standard HTTP methods (GET, POST, PUT, PATCH, DELETE), returning JSON responses that can lead to overfetching or underfetching. GraphQL uses a single endpoint where clients specify exactly the fields they need, matching the response shape to the query, but this makes caching harder and poorly written queries can overload the database. _Comparing REST and GraphQL trade-offs before an architecture decision is easier with daily.dev's technical breakdowns._ ### What is the Model Context Protocol (MCP) used for in AI applications? MCP is an open standard that defines how AI applications connect to external tools and data sources, letting a connector be built once and reused across any model that speaks the protocol. It solves the problem where AI applications previously built custom integrations for search, databases, and connectors from scratch, which broke whenever a team switched model providers. _Developers building AI agent tooling can follow MCP developments as they choose model providers, on daily.dev._ ### Why is JWT commonly used for API authentication? JSON Web Tokens are stateless, fast, and self-contained, encoding who the requester is, what they are allowed to do, and an expiry time in a compact string. Because the token carries this information, the server can verify the signature and trust its contents without looking the user up in a database, avoiding extra database calls on every request. _Anyone deciding on an authentication scheme for an API can weigh JWT trade-offs alongside other approaches on daily.dev._ ## Similar posts on daily.dev - [EP226: API Concepts Every Software Engineer Should Know](https://daily.dev/posts/ep226-api-concepts-every-software-engineer-should-know-rh6pqv5zh) · ByteByteGo · 15 upvotes · 1 comments - [Learn How to Deploy, Secure, and Automate Full-Stack Web Apps](https://daily.dev/posts/learn-how-to-deploy-secure-and-automate-full-stack-web-apps-bjh2ruxgg) · freeCodeCamp · 2 upvotes · 0 comments --- Tags: [#architecture](https://daily.dev/tags/architecture), [#graphql](https://daily.dev/tags/graphql), [#rest-api](https://daily.dev/tags/rest-api), [#flask](https://daily.dev/tags/flask), [#grpc](https://daily.dev/tags/grpc) [View this post on daily.dev](https://daily.dev/posts/complete-apis-crash-course-in-14-minutes-w-free-project-vishakha-sadhwani-pdcflaelo) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"COMPLETE APIs Crash Course In 14 Minutes [w/ FREE Project] | Vishakha Sadhwani","url":"https://daily.dev/posts/complete-apis-crash-course-in-14-minutes-w-free-project-vishakha-sadhwani-pdcflaelo","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/complete-apis-crash-course-in-14-minutes-w-free-project-vishakha-sadhwani-pdcflaelo"},"datePublished":"2026-07-08T05:08:16.236Z","dateModified":"2026-09-13T21:40:36.387Z","description":"A beginner-friendly crash course covering API fundamentals from the ground up.
