# Check mutuals on X

Find mutual follows and followers-you-know between X accounts.

## Choose an endpoint

| Endpoint | Purpose | Usage |
|---|---|---|
| GET /x/users/{id}/followers-you-know | Mutual followers the acting account sees | Read tier |
| GET /x/followers/check?source=<a>&target=<b> | Does A follow B? | Read tier |

The base URL is `https://xquik.com/api/v1`. Authenticate with the `x-api-key: xq_...` header.

## Compare the accounts

1. Ask for two handles.
2. For an A vs B mutual check, call `GET /x/followers/check?source=<a>&target=<b>` and reverse. `source` and `target` may be handles or numeric IDs.
3. To find followers shared by A and B, resolve B with `GET /x/users/{id}`. The lookup accepts a username. Then call `GET /x/users/{id}/followers-you-know` through a connected account.
4. Present as a small list with bios.
