Trend API
The Trend platform API — the NestJS backend behind app.trend.io and the Trend creator app. It exposes 124 operations across brand accounts and approvals, campaign creation/submission/relisting, creator profiles, portfolios and levels, partnership applications and rehire invites, content submission/approval/revision, brand↔creator messaging, product shipments, AI photo generation and super-resolution, S3 pre-signed uploads, and Stripe credit-package checkout. Authentication is a JWT bearer ("access-token"); 39 admin operations additionally require a "trend-api-key" header. There is no published developer program, no onboarding for third-party developers, and no rate-limit documentation — but the OpenAPI is served publicly and unauthenticated at https://api.trend.io/docs-json.
