# Similarweb Similar Sites API

Sites similar to a domain according to Similarweb: up to 10 per domain, best match first, with rank, affinity, category and category rank. Pass the domains.

**Pricing:** $0.004 per site

**Endpoint:** `POST /v1/data/similarweb/similar-sites/run`

**Auth:** `Authorization: Bearer mk_live_...`

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `domains` | array | Yes | One or more domains (example.com, or a full URL; www and paths are ignored). Each returns up to 10 similar sites. |
| `maxResults` | integer | No | How many similar sites to return per domain, best match first. Similarweb lists up to 10 per domain; defaults to 10 (all of them). |

## Example

`?wait=true` holds the request open until the run finishes (up to 60s) and returns the rows inline: one request, no polling.

```bash
curl -X POST "https://api.mindcase.co/v1/data/similarweb/similar-sites/run?wait=true" \
  -H "Authorization: Bearer mk_live_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"params":{"domains":["..."]}}'
```

```python
import requests

resp = requests.post(
    "https://api.mindcase.co/v1/data/similarweb/similar-sites/run",
    params={"wait": "true"},
    headers={"Authorization": "Bearer mk_live_YOUR_API_KEY"},
    json={"params": {
    "domains": [
        "..."
    ]
}},
)
rows = resp.json()["data"]
```

## Longer runs

If the run is still going at the 60s ceiling you get back `{ job_id, status: "running" }` instead of rows (same if the result is over 100 rows; those come back `truncated`). Poll with that `job_id`:

```bash
# 1) check status
curl https://api.mindcase.co/v1/jobs/JOB_ID \
  -H "Authorization: Bearer mk_live_YOUR_API_KEY"

# 2) when status == completed, fetch the rows
curl https://api.mindcase.co/v1/jobs/JOB_ID/results \
  -H "Authorization: Bearer mk_live_YOUR_API_KEY"
```
