## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tiktok-comment-replies-fetcher-c340fb61
```

Example prompt: Pull the replies to comment ID 7516594811735000001 on the TikTok video at https://www.tiktok.com/@tiktok/video/7516594811734854943 — fetch 3 pages of replies and include AI sentiment analysis on each one.

## When to prefer this

Use this endpoint when you need to retrieve the full reply thread for a specific TikTok comment, especially when you already have a comment ID (e.g., from a prior video comments fetch). It is the right choice when you want to drill into a conversation thread rather than top-level comments, and when optional AI-powered emotion/sentiment analysis per reply is valuable. Prefer this over generic scraping tools when you want structured reply data with pagination support up to 1000 pages.

## Known failure modes

- Missing comment_id parameter — returns validation error
- Both url and video_id provided — returns ambiguous input error
- Neither url nor video_id provided — returns missing parameter error
- Invalid or deleted TikTok video URL — returns not found error
- Comment ID not found on the specified video — returns empty or not found response
- Pages value out of range (below 1 or above 1000) — returns validation error
- TikTok rate limiting or private video — may return access denied or empty results

## How this service works

Get the replies to one comment (its thread) by video URL or numeric video ID plus the comment ID.

## Output

Returns a paginated list of reply objects for the specified TikTok comment. Each reply includes the reply text, author info, timestamps, like counts, and optionally a sentiment object with joy, trust, fear, surprise, sadness, disgust, anger, and anticipation scores (0–100), a dominant emotion, emotional intensity (0–10), and polarity (positive, negative, or neutral).
