- Billed: Per record
- Free to start: $0.10
- Endpoint: POST /v1/facebook

## What people build with the Facebook Ad Library API

- **Competitive ad research.** Every ad a competitor is running right now, with the copy and the landing page.
- **Find advertisers.** Check which businesses spend on ads and how long their ads have run.
- **Messaging research.** See how a market talks to its buyers before you write your own campaigns.

## Quote it, then run it

1. free quote: the exact price, nothing charged:

```bash
curl -X POST https://apiforagents.dev/v1/facebook \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"ads","subjects":["nike"],"status":"active","limit":25,"estimateOnly":true}'
```

2. the same call, run:

```bash
curl -X POST https://apiforagents.dev/v1/facebook \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"ads","subjects":["nike"],"status":"active","limit":25}'
```

## Inputs

Everything you can send in one ads call. Required inputs first.

| Input | Type | What it does |
|---|---|---|
| subjects * | text list | Page URLs or vanity handles. 1-5 items |
| status | enum | "active": ads running now; "inactive": ads that have stopped. |
| limit | integer | 1-100 |

## What comes back

The fields of every row, always present. Nothing is guessed: a value that could not be measured is null, and the answer's coverage says why.

| Field | Type |
|---|---|
| libraryId | string |
| adUrl | string |
| pageUrl | string |
| advertiser | any |
| isActive | boolean |
| startDate | string |
| endDate | string |
| daysActive | integer |
| headline | string |
| bodyText | string |
| linkDescription | string |
| ctaText | string |
| destinationUrl | string |
| mediaType | string |
| mediaUrl | string |
| format | string |
| variantCount | integer |
| platforms | list of string |
| euReach | integer |
| reachBreakdown | any |
| cards | any |
| details | object |

details is always the last field: everything else the source sent for that row, under our own field names. Its keys depend on the source that answered, so read them defensively; it is {} when there is nothing more.

## A sample answer

Made-up names and values in the real field names, so you can see the shape before you spend anything.

| advertiser | isActive | startDate | daysActive | headline | bodyText |
|---|---|---|---|---|---|
| Brewlab Coffee | true | 2026-10-01 | 15 | 20% off your first bag | Small-batch beans, roasted every Monday. |
| Brewlab Coffee | true | 2026-09-20 | 26 | Try the autumn menu | Pumpkin spice, done right. |
| Brewlab Coffee | false | 2026-08-01 | 30 | Cold brew season | Every cold brew $3 in August. |

## Pricing

Pay as you go, in US dollars, per record. No subscription, nothing expires, $5 first top-up, and every new agent starts with $0.10 free.

| Request | Records | At the list price |
|---|---|---|
| One ad | 1 | $0.0045 |
| 5 ads | 5 | $0.022 |
| A full page | 100 | $0.45 |

These are per-record list prices. Some calls also carry a minimum, such as a page of search results, so a small request can cost more than the table shows. The quote ("estimateOnly": true) is free, gives the most your exact request can cost, and the charge then settles to what came back. Records that do not come back are refunded.

## Try it without writing code

- [Open the Facebook Ad Library API in the playground](https://apiforagents.dev/dashboard/run?platform=facebook&op=ads): The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.

## Why this one, and not a scraper you run yourself

- No login, no Facebook account, no cookies, no proxies, no browser to babysit.
- When the site changes its pages, your request stays the same: keeping the reads working is our job, not yours.
- A fetch that fails costs nothing: it is named in the answer with a reason, and the quote says the most a call can cost before it runs.

## Questions

### What does the Facebook Ad Library API return?

One row per ad: advertiser, whether it is active, start date, days active, headline, body text, CTA text, media type, format, variant count, platforms, end date, library id, ad URL, page URL, destination URL and media URL.

### What do I pass in?

Up to five page URLs or vanity handles in subjects, status set to active (running now) or inactive (stopped), and a limit from 1 to 100.

### How much does it cost?

$0.0045 per ad at the list price. A small call can carry a minimum, so quote first with "estimateOnly": true, which is free and is the most the call can cost. You pay for what comes back.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.
