# `api.prefix_overlap`

Two APIs share a prefix.

Area 7, [HTTP](../topics/http.md); not declinable; the next step is usually the agent's.

Each API has a prefix of its own:

```jadpo
application {
    apis: {
        main: {
            prefix: /v1
        }
        partners: {
            prefix: /v1
        }
    }
}
```

```text
error: APIs `main` and `partners` share the prefix `/v1`
 --> app.jadpo:6:9
  |
6 |         partners: {
  |         ^^^^^^^^ same prefix
  reason: Each API's routes start with its own prefix, so a URL says which API, OpenAPI document and record it belongs to.
  next: Give `partners` a prefix of its own (agent)
