Public profile

When to use this

Pass any Facebook profile URL: a Page or a person, by username, profile.php?id= or /people/ link. type says whether it's a Page or a personal profile. Pages and personal profiles in public or professional mode return what logged-out visitors see; fields that don't apply stay null. A private personal profile returns 403 not_public and an unknown username 404 not_found; both are charged 1 credit. Facebook shows logged-out visitors the same page for a private profile and a deleted or unused profile.php id, so those return not_public too. This endpoint returns metadata, not a feed.

Parameters

All parameters go in the query string.

Example request

Replace YOUR_API_KEY with your key, or set LURKAPI_KEY for the code. Get a free key.

curl "https://api.lurkapi.com/v1/facebook/profile?url=https%3A%2F%2Fwww.facebook.com%2FNASA" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  url: "https://www.facebook.com/NASA",
});
const res = await fetch(`https://api.lurkapi.com/v1/facebook/profile?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data);

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/facebook/profile",
    params={
        "url": "https://www.facebook.com/NASA",
    },
    headers={"x-api-key": os.environ["LURKAPI_KEY"]},
    timeout=60,
)
data = res.json()
if not data["success"]:
    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data)

Example response

A real response from this endpoint, captured from the live API and trimmed to a couple of items. Strings over 96 characters (mostly signed media URLs) are cut short and end in ….

  "credits_remaining": 999999,
  "credits_charged": 1,

}

Response fields

Every field of a successful response. [] marks a list: a[].b is the b of each item in a. nullable fields can be null; optional fields can be missing.

Caching and freshness

Responses are cached for up to 10 minutes, so a repeat call within that window can return the same data. It still costs 1 credit.

Errors

Errors return { success: false, error, code, docs } with the HTTP status below. Validation errors, 401/402/429 rejections and 5xx failures are free; not_found is charged (how charging works). All error codes.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the facebook_profile tool. Ask in plain English, for example:

Use LurkAPI's facebook_profile with url "https://www.facebook.com/NASA" and summarize what you find.

Claude calls facebook_profile with arguments like these, and each call costs 1 credit:

{
  "url": "https://www.facebook.com/NASA"
}

Tool results skip nulls and empty lists to save tokens.
