Meta Ad Library — Search Ads
keyword or page ID → ad list with creatives, metrics, and pagination cursor
Language
All process output to user (progress updates, process notifications) follows the user's language.
Objective
Fetch ads from Meta Ad Library for a keyword search or a specific Facebook page, returning structured ad data with all available fields.
Prerequisites
- Browser is open on any Facebook page:
https://www.facebook.com/
- No login required for this capability
Pre-execution Checks
1. Tool Readiness
If browser-act has been confirmed available in the current session → skip this step.
Invoke browser-act via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.
Capability Components
This Skill's operational boundary = what the user can manually do in their browser. It only reads data already displayed to the user on the page, never bypassing authentication or access controls. Its role is equivalent to copy-pasting on the user's behalf — the data is already on screen, automation merely saves time. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". $(...) is bash syntax; it is recommended to use the bash tool for execution.
Below are all atomic capabilities discovered and verified during the exploration phase, listed by command template with parameters. Simply invoke them as needed — no need to read scripts/*.py source code or re-verify. Only inspect scripts when execution fails for troubleshooting. Combine freely as needed during execution.
API: search ads by keyword
eval "$(python scripts/search-ads.py --query '{keyword}' --country {country} --first {count})"
Parameters:
--query: keyword to search (mutually exclusive with --page-id)--country: 2-letter ISO country code or ALL, default ALL--active-status: active | inactive | all, default active--ad-type: ALL | POLITICAL_AND_ISSUE_ADS | HOUSING_ADS, default ALL--media-type: all | image | video | meme, default all--platforms: space-separated list, e.g. facebook instagram, default all platforms--cursor: pagination cursor from previous response's end_cursor, default first page--first: number of ads to return per page, default 10
Output example:
{
"error": false,
"count": 10,
"has_next_page": true,
"end_cursor": "AQHSmvKYSBolzAS9Wq8VSnt4...",
"ads": [
{

"ad_id": null,
"page_id": "15087023444",
"page_name": "Nike",
"page_profile_uri": "https://facebook.com/nike",
"page_profile_picture_url": "https://scontent.xx.fbcdn.net/...",
"is_active": true,
"start_date": 1773730800,

"currency": "USD",
"spend": null,
"impressions_with_index": null,

}
]
}
API: search ads by page ID
eval "$(python scripts/search-ads.py --page-id '{page_id}' --country {country} --first {count})"
Parameters:
--page-id: Facebook page ID (mutually exclusive with --query). To find a page ID: navigate to the Facebook page, the ID appears in the URL or in the page's "About" section- All other parameters same as keyword search above
Output example: same structure as keyword search above.
Enum Parameters
--active-status: active | inactive | all
--ad-type: ALL | POLITICAL_AND_ISSUE_ADS | HOUSING_ADS
--media-type: all | image | video | meme
--platforms: facebook | instagram | whatsapp | messenger | audience_network | threads (pass multiple values space-separated)
--country: ISO 2-letter country code (e.g. US, GB, DE, ALL) [collection partially done — full list of supported country codes follows ISO 3166-1 alpha-2 standard]
Pagination
API Pagination: --cursor, type: cursor, start value: omit for first page. Next page value source: end_cursor field in response. Termination: has_next_page: false.
Success Criteria
error = false AND count >= 0 AND has_next_page field present
(count may be 0 for valid queries that return no results; this is not an error)
Known Limitations
spend, impressions_with_index, reach_estimate fields are frequently null — Meta only discloses these for political/social issue ads or at their discretionad_id is often null — ad_archive_id is the reliable unique identifier- Rate limiting may occur with very high-frequency requests; add 1-2 second delays between requests in batch scripts
- Private or restricted ads may not appear in results
- The
doc_id (27201872659451053) is a compiled query ID that may change when Meta updates their frontend; if errors occur, re-explore to find the updated ID
Execution Efficiency
- Batch orchestration: Write a bash script to loop through the command templates serially within a single session; do not parallelize within one browser (prone to triggering anti-scraping restrictions). Refer to rate information in "Known Limitations" above to add appropriate intervals. To increase throughput, open multiple stealth browser sessions and distribute work across them — each session has an independent fingerprint so rate limits apply per session
- Test before batch execution: After writing a batch script, you must first test with 1-2 items to verify the script runs correctly; only then run the full batch. Never skip testing and execute in batch directly
- Reduce redundant pre-operations: When multiple steps depend on the same prerequisite state, complete them in batch under that state to avoid repeatedly establishing the same state
- Error resumption: Save results item by item during batch processing; on failure, resume from the breakpoint rather than starting over
Experience Notes
Path: {working-directory}/browser-act-skill-forge-memories/facebook-ads-scraper-facebook-ads-library-search.memory.md (working directory is determined by the Agent running the Skill, typically the project root or current working directory)
Before execution: If the file exists, read it first — it records unexpected situations encountered during past executions (e.g., a strategy has become ineffective); adjust strategy order accordingly.
After execution: If an unexpected situation is encountered (strategy became ineffective, page redesigned, anti-scraping upgraded, better path discovered), append a line:
{YYYY-MM-DD}: {what happened} -> {conclusion}
Normal execution does not write to the file. Do not record what keywords were used or how many results were returned — those are task outputs, not experience.
