Introduction | Trendtrack Public API Docs

Query emails

Returns the advanced public emails discovery surface. This endpoint is the canonical public route for richer email filters while keeping the response aligned with the stable public EmailSummary contract. The API does not expose opens, clicks, conversions, or revenue metrics; sorting is discovery-oriented metadata ordering, not best-performance scoring.

Authorization

publicApiBearer

AuthorizationBearer <token>

Provide a Trendtrack Public API key using Authorization: Bearer <api_key>.

In: header

Request Body

application/json
