Facebook Ad Library Detail Scraper API

The Facebook Ad Library Detail endpoint is one API call: send either an ID or a URL with your HProxy key and get back a clean, structured JSON object. Pull one ad from the Facebook Ad Library in full: every creative, the advertiser behind it, spend range and the dates it ran. HProxy runs the proxies, sessions, anti-bot handling and parsing server-side, so there is no headless browser to babysit and no parser to keep fixing when Facebook changes its markup. You only ever touch the JSON.

The call

One GET, and the ad library detail comes back as JSON.

Your key goes in one header. 1 required parameter, and the answer is the object below it.

Facebook ad library detail questions

Answered before you ask.

The reference

Send one authenticated HTTPS request to the Facebook Ad Library Detail endpoint with either an ID or a URL and your HProxy API key. Pull one ad from the Facebook Ad Library in full: every creative, the advertiser behind it, spend range and the dates it ran. No proxies, no headless browser and no parsing on your side. The response is ready-to-use JSON.

This endpoint is 0.15¢ per successful call, which is $1.49 per 1,000. It bills from your HProxy balance with no subscription and no monthly minimum. Errors are retried and never charged; a lookup whose target does not exist counts as a call.

The API only accesses publicly available Facebook data, the same pages anyone can open in a browser. You are responsible for using the data in line with applicable laws and Facebook's terms for your use case.

A structured JSON object with the full ad library detail data Facebook exposes publicly. See the fields listed above. The schema is consistent across calls, so you integrate once and rely on it.

No. Every call runs on HProxy's own residential network behind the scenes, so requests look like real users. The proxy layer is already included in the per-call price.

Docs and AI

Connect your scraper to an AI, any time.

The whole Scraper API is published as markdown, so an assistant reads every endpoint, every parameter and a real response without a key and writes your integration. And because a scrape is one GET that answers in JSON, an agent can run the scraper itself, on its own schedule, with your key.

An agent can call it

One GET with your key returns structured JSON, so an agent scrapes on its own schedule. No browser to drive, no parser to keep alive between runs.

More on the Facebook Ad Library Detail API

What the Facebook Ad Library Detail endpoint returns

Pull one ad from the Facebook Ad Library in full: every creative, the advertiser behind it, spend range and the dates it ran. The JSON object carries creatives[], advertiser, spend / impressions and dates. Nothing is summarised away on our side, so what you read in the response is what the Facebook ad library detail page itself holds.

What you send to the Facebook Ad Library Detail API

The call takes either an ID or a URL, and any one of id and url satisfies it. Optional: id, url, get_transcript, trim and cache_max_age. Your key travels in the X-API-Key header, the response is JSON, and the call is billed at 0.15¢, $1.49 per 1,000.

Ads on other platforms

The same ads data is available on 2 other platforms: LinkedIn Ad Detail and Google Ad Detail. They share this endpoint's JSON shape, its per-call billing and your one API key, so moving from Facebook to another network is a change of URL rather than a second integration.

Is scraping Facebook ad library detail allowed?

The endpoint reads publicly available Facebook data, the same pages anyone can open in a browser without logging in. It does not touch private accounts or anything behind a password. How you then use the data is yours to keep lawful, under the rules that apply to you and to Facebook.

Ready when you are.

Your dashboard is ten seconds away. No sales call, no subscription, no minimum.
