# Errors

> Error-handling conventions for future Blockchain Library APIs.

## Recommended response behavior

API errors should use stable machine-readable codes, human-readable messages, and appropriate HTTP status codes.

```json theme={null}
{
  "error": {
    "code": "INVALID_REQUEST",
    "message": "The request could not be processed."
  }
}
```
