Everything needed to connect an AI client, understand the response contract and plan a research budget.

Canonical: https://socialtoai.com/docs/

## Start here

Quickstart connects your client by Remote MCP or the HTTP API within the 2 credit trial. Verbs describes the six core inputs, the shared response envelope and pagination. Projection explains which fields are kept and what an absent field means. Errors, retries and charges explains free failures, billable empty results and safe replay.

## Research packs

Optional packs add explicitly granted, separately priced operations to a Key: KOL for creator research on Douyin and Xiaohongshu, Commerce for Xiaohongshu products and reviews, Index for Douyin content, brand and creator indices, and Raw for bounded native platform operations. Each pack keeps the same envelope and billing rules.
