Introduction

Welcome to the JSON Repair API documentation. Our service provides a high-concurrency, sub-millisecond API for repairing malformed JSON and validating it against custom schemas.

Ultra Fast

Built with Elixir/Phoenix for maximum performance and low latency.

Secure

Industry-standard SHA256 hashing for API keys and secure authentication.

Authentication

All API requests must be authenticated using an API key. You can generate keys in your Dashboard.

We support two methods of passing the API key:

Authorization: Bearer YOUR_API_KEY

x-api-key: YOUR_API_KEY

POST /api/repair

The primary endpoint for repairing and validating JSON payloads.

Request Body

Property	Type	Description
json	string	The malformed JSON string you wish to repair.
schema	object	Optional. A valid JSON Schema to validate the repaired JSON against.
debug	boolean	Optional. If true, the response will include the original input string.
