> **For coding agents and LLMs:** This is one page from the Social Fetch docs (markdown export). For curated orientation and workflow guidance, start with [`/llms.txt`](https://www.socialfetch.dev/llms.txt); for agent onboarding and crawl rules, use [`/agents.txt`](https://www.socialfetch.dev/agents.txt); for the full endpoint list with links to pages like this one, use [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt); for one platform's parameters and curls, use [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt); use [`/llms.json`](https://www.socialfetch.dev/llms.json) when you need structured JSON for tool registration.

- Outcome semantics such as `found`, `not_found`, and `private` are documented in [Errors](https://www.socialfetch.dev/docs/errors.mdx) and on operation pages when present in the OpenAPI contract.

## Markdown docs convention

- Every docs page has a markdown twin: append **`.mdx`** to the docs pathname (for example `/docs/quickstart` → `/docs/quickstart.mdx`).
- Agents that send `Accept: text/markdown` on `/docs/**` HTML URLs may receive markdown directly (same URL, `Vary: Accept`).

# Facebook Ad Library aggregation (https://www.socialfetch.dev/docs/recipes/facebook-ad-library)

Pull public Meta Ad Library creatives for competitive research. Two complementary paths: keyword search across the library, and company/page ad lists when you already know the advertiser.

**You'll need** an [API key](https://app.socialfetch.dev/api-keys) and the [TypeScript SDK](/docs/sdk). Platform overview: [Facebook](/platforms/facebook).

Credit budget

  Facebook Ad Library search, company lists, company search, and single-ad get are **1 credit** per successful request (per page when paginating). Empty pages still bill when the lookup completes. Trust `meta.creditsCharged`.

Routes

| Goal                 | Route                                                                                                   | SDK                                                            |
| -------------------- | ------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------- |
| Keyword search       | [`GET /v1/facebook/ad-library/ads/search`](/docs/api/v1/facebook/ad-library/ads/search/get)             | `client.facebook.searchAdLibraryAds({ query, … })`             |
| Find advertisers     | [`GET /v1/facebook/ad-library/companies/search`](/docs/api/v1/facebook/ad-library/companies/search/get) | `client.facebook.searchAdLibraryCompanies({ query })`          |
| List a company's ads | [`GET /v1/facebook/ad-library/companies/ads`](/docs/api/v1/facebook/ad-library/companies/ads/get)       | `client.facebook.listCompanyAds({ pageId?, companyName?, … })` |
| One ad by URL/id     | [`GET /v1/facebook/ad-library/ads`](/docs/api/v1/facebook/ad-library/ads/get)                           | `client.facebook.getAdLibraryAd({ url?, adId?, … })`           |

Useful filters on search / company lists: `country`, `status` (`active` / `inactive` / `all`), `mediaType`, `sortBy` (`impressions` / `most-recent`), `startDate` / `endDate`, `cursor`.

Keyword search

```ts
import { SocialFetchClient } from "@socialfetch/sdk";

const client = new SocialFetchClient({
  apiKey: process.env.SOCIALFETCH_API_KEY!,
});

const page = await client.facebook.searchAdLibraryAds({
  query: "running shoes",
  country: "US",
  status: "active",
  mediaType: "video",
  sortBy: "most-recent",
});

if (!page.ok) {
  console.error(page.error.code, page.error.requestId);
  return;
}

for (const ad of page.value.data.ads ?? []) {
  console.log(ad);
}

console.log(page.value.meta.creditsCharged, page.value.data.page);
```

Resolve advertiser, then list ads

```ts
const companies = await client.facebook.searchAdLibraryCompanies({
  query: "Acme Coffee",
});

if (!companies.ok) {
  console.error(companies.error.code, companies.error.requestId);
  return;
}

const first = companies.value.data.companies?.[0];
if (!first?.pageId) return;

const ads = await client.facebook.listCompanyAds({
  pageId: first.pageId,
  status: "active",
  sortBy: "impressions",
});

if (!ads.ok) {
  console.error(ads.error.code, ads.error.requestId);
  return;
}

console.log(ads.value.data.lookupStatus, ads.value.data.ads?.length);
```

If you already know the advertiser name, skip company search and call `listCompanyAds({ companyName: "Acme Coffee", status: "active" })` directly.

Paginate with `data.page.nextCursor` while `hasMore` is true. Keep the same filters on every page.

Optional: other ad libraries

Same product idea, different networks:

* [TikTok Ad Library search](/docs/api/v1/tiktok/ad-library/ads/search/get)
* [LinkedIn Ad Library search](/docs/api/v1/linkedin/ad-library/ads/search/get)
* [Google Ad Library](/docs/api/v1/google/ad-library/companies/ads/get) (company ads are priced higher — see that operation page)
