# Forum Topic Activity — String Normalisation + Duplicate Key Report

> Forum Topic Activity — String Normalisation + Duplicate Key Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Normalises string fields and identifies duplicate keys in forum topic activity records (thread_count, reply_count) for up to 200 rows, returning two independent analytical reports.

## 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 forum-topic-activity-string-normalisation-duplicate-key-report-1b0aa506 -d '<json body>'
```

Example prompt: I have up to 200 rows of forum topic activity data with fields like row_id, channel_group, date, thread_count, and reply_count — can you run string normalisation and a duplicate key check on them and give me both reports?

## When to prefer this

Choose this endpoint when you have forum topic activity data (thread counts, reply counts by channel group and date) that needs both string field standardisation and duplicate key detection in a single low-cost call. It is ideal for pre-ingestion data quality checks on forum exports of up to 200 rows where no live lookups, predictions, or external actions are needed. Prefer it over generic data cleaning tools when you specifically need these two report types bundled at $0.01 USDC.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, channel_group, date, thread_count, reply_count) — validation error
- Malformed date format (must match YYYY-MM-DD pattern) — schema validation failure
- Empty rows array — minimum 1 item required
- Numeric values outside allowed range (±1,000,000,000,000) — schema rejection
- Payment not included or insufficient — x402 payment required error

## How this service works

Forum topic activity — String normalisation + Duplicate key report: String normalisation + Duplicate key report for supplied forum topic activity records (thread_count, reply_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two independent reports: (1) a string normalisation report showing cleaned/standardised values for string fields (row_id, channel_group, date), and (2) a duplicate key report identifying rows sharing the same key fields — all computed locally without external lookups, covering up to 200 input rows.
