# Transaction Fee Observations — Record Quality Audit + String Normalisation + Numeric Distribution

> Transaction Fee Observations — Record Quality Audit + String Normalisation + Numeric Distribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Runs three local analytical reports (record quality audit, string normalisation, and numeric distribution) on up to 200 rows of transaction fee observation data containing fee_units and transaction_count fields.

## 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 transaction-fee-observations-record-quality-audit-string-e3e851f2 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and numeric distribution analysis on my transaction fee observations? Here are up to 200 rows with fields row_id, instrument_group, date, fee_units, and transaction_count — focus the numeric analysis on the fee_units field.

## When to prefer this

Choose this endpoint when you have a batch of transaction fee observation records (up to 200 rows) and need three simultaneous data quality reports — quality audit, string normalisation, and numeric distribution — in a single low-cost call. Prefer this over general-purpose data tools when your data specifically contains fee_units and transaction_count fields with instrument_group categorisation. It is ideal for pre-ingestion validation, finance data pipeline checks, or quick profiling of fee datasets without requiring any external data sources or live lookups.

## Known failure modes

- Rows array is empty or missing — minimum 1 row required
- More than 200 rows submitted — exceeds maximum batch size
- Invalid date format in any row — must match YYYY-MM-DD pattern
- row_id missing or blank — required per row
- Numeric fields (fee_units, transaction_count) out of allowed range (±1,000,000,000,000)
- Invalid field selector — must be either 'fee_units' or 'transaction_count'
- Payment not included or incorrect — $0.01 USDC required per call

## How this service works

Transaction fee observations — Record quality audit + String normalisation + Numeric distribution: Record quality audit + String normalisation + Numeric distribution for supplied transaction fee observations records (fee_units, transaction_count). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent reports: (1) a record quality audit detailing completeness, missing values, and structural issues across all rows; (2) a string normalisation report covering the instrument_group and other string fields; and (3) a numeric distribution summary (e.g. min, max, mean, percentiles) for the selected numeric field (fee_units or transaction_count). All analysis is performed locally on the supplied data with no external lookups.
