GET /v1/projects/:projectId/ads/ads

Lists individual ads under the project, across platforms. Phase 1 ships meta_ads + tiktok_ads only — Apple Search Ads has no equivalent layer junction (ASA bottoms out at the ad-group level), so it is intentionally excluded here. Each ad carries its parent adset and campaign and the adsContentId that lets you join back to ads-content when the ad was promoted from a Layers-scored creative.

Example request

curl "https://api.layers.com/v1/projects/prj_01HX9Y7K8M2P4RSTUV56789AB/ads/ads?adsetId=adg_01HXG9&status=active" \
  -H "Authorization: Bearer lp_live_01HX9Y6K7EJ4T2_4QZpN..."

const res = await fetch(
  `https://api.layers.com/v1/projects/${projectId}/ads/ads?adsetId=${adsetId}&status=active`,
  { headers: { Authorization: `Bearer ${apiKey}` } },
);
const { items, nextCursor } = await res.json();

// Find every platform a creative is live on.
const byCreative = new Map<string, string[]>();
for (const ad of items) {
  if (!ad.adsContentId) continue;
  const platforms = byCreative.get(ad.adsContentId) ?? [];
  platforms.push(ad.platform);
  byCreative.set(ad.adsContentId, platforms);
}

Joining ads to creatives

Every ad in this response has at most one adsContentId. That field is the bridge to ads-content (the scored creative), top-performers (cross-source ranking), and — for generated content — the source content_container. Use it to answer:

• "Where is this creative running?" Query /ads?adsContentId=adc_01HXC9...
• "What score does this ad's creative have?" Follow adsContentId to /ads-content?adsContentId=... or the item directly at the row level.
• "Is this ad's creative manually overridden?" Same path — the override lives on the ads-content row.

adsContentId is null only for ads that existed on the platform before Layers tracked them or for creatives outside the scoring pool (rare; mostly legacy imports). Do not rely on null being stable.

Notes

• status is the partner-normalized status mapped from the layer junction's record (one of active, paused, archived, deleted, in_review, rejected).
• effectiveStatus, creative, sourceType, launchedAt: reserved for future enrichment from platform-native ad rows. They are always null in Phase 1; partners that need creative metadata or the platform-derived effective status must call the platform's own ad manager.
• metricsSnapshot7d is reserved (always {} today). For paid performance, call GET /v1/projects/:projectId/ads-metrics with scope=ad and an explicit window.
• name defaults to the platform-native ad id (externalId) when Layers doesn't have a friendlier label cached.
• adsContentId is the bridge to ads-content. When non-null, the ad was promoted from a Layers-scored creative; when null, the ad was created outside the Layers refresh loop.
