# Geo compare

The same page from 2–5 countries at once, side by side, with a diff of what changes between them. `POST https://cdpfleet.com/v1/functions/geo` → `application/json`.

 

```bash
curl -s https://cdpfleet.com/v1/functions/geo \
  -H "x-api-key: $CDPFLEET_API_KEY" -H "content-type: application/json" \
  -d '{"url":"https://www.google.com/","countries":["us","de","jp"],"formats":["markdown","screenshot"]}' -o geo.json -D - | grep -i '^x-call-id'
```

```js
// Node.js 18+: save as geo.mjs, run node geo.mjs
const res = await fetch('https://cdpfleet.com/v1/functions/geo', {
  method: 'POST',
  headers: { 'x-api-key': process.env.CDPFLEET_API_KEY, 'content-type': 'application/json' },
  body: JSON.stringify({
    url: 'https://www.google.com/',
    countries: ['us', 'de', 'jp'],
    formats: ['markdown', 'screenshot'],
  }),
  signal: AbortSignal.timeout(30000),
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`); // 429: wait Retry-After seconds
console.log(await res.text());
```

## Fields

| Field | Type | Default | What it does |
| --- | --- | --- | --- |
| `url` | string | required | The page to load. A public `http` or `https` address: private, loopback, link-local, CGNAT and cloud-metadata addresses, `localhost`, `.local`/`.internal` names and names that resolve to them are refused (`400 invalid_url`). |
| `country` | string | `"random"` | Two-letter country for the exit IP and for the page's locale, timezone, geolocation and `Accept-Language` (see [countries](#countries)); `"random"` picks one. Unknown codes: `400 invalid_country`. |
| `max_wait` | number | `20` | Seconds to wait for the page to load, 1–60 (`400 invalid_option` otherwise). The whole call returns within about `max_wait` + 5 s, so a client timeout of `max_wait` + 10 s is safe. A page that is still loading then comes back partial (below); one that never started: `408 page_timeout`. |
| `proxy` | string or string\[\] | the Community proxy | Omit it to use the free Community proxy in `country`. Or: your own proxy URL (`http://`, `https://`, `socks5://`), a list (one is picked per call), a `cdpfleet-plan…` token, or a residential `cdpfleet-resi…` token (tier, country, device OS, sticky session) billed per GB to your residential balance ([proxies](https://cdpfleet.com/docs/proxies)). `proxy_rules` isn't supported yet (`400 invalid_option`). |
| `countries` | string\[\] | required | 2–5 [country codes](#countries), no duplicates. The first is the baseline the others are compared with. Each runs through the Community proxy in that country, unless you pass `proxy`. |
| `formats` | string\[\] | `["screenshot", "markdown"]` | Any [scrape](https://cdpfleet.com/docs/functions/scrape) formats, returned per country. |

## Good to know

-   Response: `results {us: {status, url, partial?, …formats}, de: {…}}` and `diff {markdown: {de: "--- us\n+++ de\n…"}}` — a unified diff of each text format (`markdown`, `text`, `html`) against the first country. `url` is where each country ended up after redirects (a site may send a country to another domain).
-   A country that fails gets `error` in its result instead of failing the call, and its diff is `null` — as is every diff when the first country fails; `""` means the pages were identical.
-   Where a site places an exit is up to the site: it can read a Community exit as another country than the one asked for (case [geo compare](https://cdpfleet.com/docs/cases/geo-compare)). Check each country's `url`, language and currency before relying on it.
-   The countries run in parallel, so the call holds one thread per country while it runs.
