## Troubleshooting

If requests fail, run `zero doctor check-connector --env-name SIMILARWEB_TOKEN` or `zero doctor check-connector --url https://api.similarweb.com/capabilities --method GET`

## Core APIs

### Check API Capabilities

Check what data your API key has access to:

```bash

```

### Total Traffic and Engagement

Get total visits for a domain. Replace `<domain>` with the target domain (e.g., `amazon.com`):

```bash
curl -s "https://api.similarweb.com/v1/website/<domain>/total-traffic-and-engagement/visits?api_key=$SIMILARWEB_TOKEN&start_date=2025-01&end_date=2025-03&country=world&granularity=monthly&main_domain_only=false" | jq '.[] | {date, visits}'
```

### Engagement Metrics (Pages per Visit, Average Duration, Bounce Rate)

```bash
curl -s "https://api.similarweb.com/v1/website/<domain>/total-traffic-and-engagement/pages-per-visit?api_key=$SIMILARWEB_TOKEN&start_date=2025-01&end_date=2025-03&country=world&granularity=monthly&main_domain_only=false" | jq '.[] | {date, pages_per_visit}'

```

```bash

```

### Traffic Sources Overview

## Batch API

### Check Batch API Credits

curl -s "https://api.similarweb.com/v3/batch/tables/describe" --header "api-key: $SIMILARWEB_TOKEN" | jq '.tables[] | {name, description}'
```

## Guidelines

1. **Date format**: Use `YYYY-MM` for `start_date` and `end_date` parameters (e.g., `2025-01`).
2. **Country codes**: Use ISO 2-letter codes (e.g., `us`, `gb`, `de`) or `world` for worldwide data.
3. **Granularity**: Use `monthly`, `weekly`, or `daily` for time-series data.
4. **Rate limits**: The API has rate limits based on your subscription. If you get 429 errors, wait before retrying.
5. **Domain format**: Use bare domain without protocol (e.g., `amazon.com`, not `https://amazon.com`).
6. **main_domain_only**: Set to `false` to include subdomains, `true` for the main domain only.
