# Invalid request body

> HTTP 400, code invalid_request_body

<Note>The problem document's `type` field points here: `https://docs.costgraph.ai/pricing/errors/invalid_request_body`</Note>

```json theme={null}
{
  "type": "https://docs.costgraph.ai/pricing/errors/invalid_request_body",
  "title": "Invalid request body",
  "status": 400,
  "code": "invalid_request_body"
}
```

## When you see it

The request body is not valid JSON, or is not the shape the endpoint expects.

## What to do

Check that the body is well-formed JSON with the right content type, and that the fields match the endpoint's schema.
