Go HTTP API Contract IO

Consistent HTTP request and response handling for Go servers and clients, with strict JSON decoding, DTO-based validation, and standardized API errors.

go get go.leoweyr.com/go-http-api-contract-io/v3

The library generates a standardized error response body designed for consistent API communication:

{
  "error": {
    "message": "VALIDATION_FAILED",
    "details": {}
  }
}
