5 free APIs to use in your next app

1) Lorem Picsum

What it is: Free placeholder image service.
Key feature: Generate placeholder images by specifying dimensions in the URL — useful for mockups or unfinished UIs.
Use case: Quickly populate image slots in prototypes or during front-end development.
Example:
- https://picsum.photos/300/200

2) JSONPlaceholder

What it is: Fake REST API that returns realistic test data (posts, users, comments, todos, etc.).
Key feature: Ready-made endpoints to seed or test front-end and back-end logic without building a real API.
Use case: Development and automated testing when you need predictable sample data.
Common endpoints:
- /posts
- /users
- /comments

3) Open Food Facts

What it is: Crowdsourced food product database.
Key feature: Lookup by barcode and retrieve nutritional info, common names, ratings, and other product metadata.
Use case: Build barcode scanners, nutrition-tracking features, or product info pages.
Integration note: Query by barcode to fetch product JSON for display or processing.

4) DigiDates (date/time utility)

What it is: Time/date utilities for conversions, validation, and human-readable formatting (subtitle may be inaccurate).
Key features: Timezone handling, format conversions, validation, and readable date strings.
Use case: Scheduling, display of relative times, date validation in forms.
Alternatives: If the name is unfamiliar, consider Day.js, date-fns, or Luxon for lightweight, free libraries.

5) Wit.ai (referred to as “what AI”)

What it is: Free NLP platform for parsing natural language into intents and entities.
Key feature: Classic NLP (not an LLM) for intent recognition, entity extraction, and voice/text queries.
Use case: Voice assistants, IoT command parsing, chat interfaces where you need structured meaning from user input.
Integration note: Train intents/entities in the console and connect via REST API or SDK.

Quick mini-guides / integration tips

Lorem Picsum: Insert an image URL with width × height params (e.g., https://picsum.photos/width/height) to display placeholders.
JSONPlaceholder: Call endpoints like /posts or /users during front-end development and swap them later for your real API.
Open Food Facts: Query by barcode to fetch product JSON; use the returned data for nutrition labels or product lookups.
Date utilities: Choose a lightweight library (Day.js or date-fns) for client-side conversions and validation; format dates for locales.
Wit.ai: Train intents/entities in the console, then connect via REST API or SDK; use webhooks or intent handlers to act on parsed commands.

Main speaker / source: Single narrator from the video. Subtitles mention a name that appears as “Lauren,” but this may be an auto-transcription error — the speaker is an unnamed video presenter.
