## O que é MockAPI Dog?

MockAPI Dog is a free tool for creating mock REST APIs and LLM streaming endpoints for development and testing. It is designed to let developers spin up endpoints quickly without signup, configuration files, or API keys.

The workflow is simple: generate an endpoint, choose a response type, and save. After that, the mock API is live immediately and can be copied into frontend prototypes, API tests, or AI integration experiments.

## O que MockAPI Dog pode fazer?

### No-signup endpoint creation

Create a mock endpoint without setting up accounts, API keys, or project files. The page flow is designed to get a usable URL in seconds.

### REST and LLM mocking

Choose between conventional REST responses and LLM-style streaming endpoints for AI integration testing.

### Streaming format support

Return JSON responses or simulate provider-like streaming for OpenAI, Anthropic, and generic formats.

### Response and failure simulation

Use built-in controls for status codes, delays, random failures, and conditional errors to exercise error handling paths.

### Built-in JSON editor

Edit JSON directly with syntax highlighting and validation before saving the mock endpoint.

### HTTP method and CORS support

Support standard HTTP methods and CORS so endpoints can be used from browser-based clients and typical API workflows.

## Casos de uso

### Frontend development

Build a UI against a stable mock endpoint while the real backend is still unavailable or in progress.

### AI integration testing

Test chatbot or LLM-powered features with streaming responses before connecting to paid production APIs.

### Error handling and edge cases

Check how an application handles 404s, 500s, artificial latency, and other failure conditions.

### Rapid prototyping

Create quick API demos or proofs of concept without setting up infrastructure or authentication.

### Training and education

Provide consistent endpoints for lessons, exercises, or workshops where students need predictable API behavior.

### Can I use this for production?

MockAPI Dog is positioned for development, testing, and prototyping rather than live production use. The FAQ recommends production-grade APIs for live applications.

### What LLM providers are supported?

The site says it supports OpenAI format, Anthropic format, and generic streaming formats, with mock responses that mimic provider streaming behavior.

### How long do endpoints stay active?

Endpoints remain active as long as they are being used. The site notes that inactive endpoints may be cleaned up periodically to maintain service quality.
