API Mock Service

Dynamic API endpoint mocker that captures all requests to /api/mock/* endpoints and stores them for analysis. Perfect for testing webhooks, debugging API integrations, and Vercel deployments.

Features

• Dynamic endpoint capture: Any request to /api/mock/{slug} gets logged
• All HTTP methods supported: GET, POST, PUT, PATCH, DELETE
• Request logging: Headers, body, query parameters, and timestamps
• Slug-specific storage: Separate Redis lists per endpoint slug
• Automatic cleanup: 24-hour TTL with memory optimization
• Redis storage: Uses Vercel KV for log persistence

Usage

Send requests to any API endpoint:

# These all get captured and logged
curl -X POST http://localhost:3000/api/mock/webhook -d '{"test": "data"}'
curl -X GET http://localhost:3000/api/mock/health?param=value
curl -X PUT http://localhost:3000/api/mock/users -d '{"name": "John"}'

View logs:

# Get last 5 logs for specific endpoint (default)
curl http://localhost:3000/api/read/webhook

# Get more logs from specific endpoint
curl http://localhost:3000/api/read/webhook?limit=10

# View logs with formatted output
curl -Ss http://localhost:3000/api/read/health?limit=3 | jq
