| Tool | Description | Behaviour |
|---|---|---|
| check_page | Check whether a web page's Meta, TikTok and OpenAI pixels work (the Meta Pixel is the former Facebook Pixel), with a grade for each: cookie consent, duplicate events, event IDs, the ad click IDs (e.g. fbclid -> _fbc) and signs of server-side tracking. A browser in the EU visits the page twice. Reuses a result from the last 24 hours unless recheck is true. Waits for the result up to wait_seconds (a check takes 20 to 60 seconds); if it is still running, call get_report later. | Changes data |
| get_fix_guide | Step-by-step guide (Markdown) for fixing a problem the check found, for the site's platform when one exists (otherwise the general version). With consent_tool, returns the guide for wiring the Meta, TikTok and OpenAI pixels to that consent tool instead. Guides exist for: meta.fires_before_consent, meta.not_firing_after_consent, meta.duplicate_pixel, meta.missing_event_id, meta.fbc_not_set, meta.server_copy_without_event_id, meta.server_event_id_mismatch, tiktok.fires_before_consent, tiktok.not_firing_after_consent, tiktok.event_id_reused, tiktok.duplicate_pixel, tiktok.missing_event_id, tiktok.click_id_not_set, tiktok.mobile_cta_tracking_mismatch, tiktok.multiple_pixels, tiktok.server_copy_without_event_id, tiktok.server_event_id_mismatch, openai.fires_before_consent, openai.not_firing_after_consent, openai.event_id_reused, openai.duplicate_pixel, openai.missing_event_id, openai.click_id_not_set, openai.mobile_cta_tracking_mismatch, openai.multiple_pixels, openai.server_copy_without_event_id, openai.server_event_id_mismatch. Setup guides (pass the id as issue_id): general.server_side_not_detected (setting up the Meta Conversions API), tiktok.events_api_setup (setting up the TikTok Events API), openai.pixel_setup (installing the OpenAI Pixel), openai.conversions_api_setup (setting up the OpenAI Conversions API). | Read-only |
| get_report | Read the result of a check by its report id or report link (https://ispixelworking.com/r/<id>): status, a grade for each pixel found (Meta, TikTok and OpenAI), problems with explanations and fix guide links, checklist. Reports are kept for 90 days. | Read-only |
| list_findings | Every problem (finding) the check can report, with id, severity, title, explanation and whether a fix guide exists. | Read-only |
