Questions about apple_ads_target_cpa_suggestion
What Apple thinks an install should cost you. Returns the suggested target CPA for an app — the MAXIMUM tap-install CPI Apple observed across that app’s eligible markets over the last 28 days, together with the market that produced it. Only markets with at least 10 installs in that window qualify, so a brand-new or low-volume app legitimately has no suggestion yet and that is an answer, not a failure. This is the number to put on a MAX_CONVERSIONS campaign, where the campaign-level bid IS the target CPA — it is NOT a per-tap bid and does not belong on a MANUAL_CPT campaign, which refuses a campaign-level bid outright. Scope it with countriesOrRegions to ask about specific markets. Read-only, free, spends nothing. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data.
