# Transaction Fee Observations — Record Quality Audit + Keyed Dataset Comparison

> Transaction Fee Observations — Record Quality Audit + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Runs a record quality audit and keyed dataset comparison on up to 200 rows of transaction fee observations (fee_units, transaction_count) and returns 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 transaction-fee-observations-record-quality-audit-keyed-dataset-81c2e70b -d '<json body>'
```

Example prompt: Can you run a record quality audit and keyed dataset comparison on these two sets of transaction fee observations — I've got up to 50 rows each with fee_units and transaction_count grouped by instrument_group, and I want two separate reports back on data quality and any differences between the datasets?

## When to prefer this

Choose this endpoint when you need both a data quality audit and a side-by-side keyed comparison of two transaction fee observation datasets in a single call for a flat fee of $0.01 USDC. It is best suited for offline/batch validation of up to 200 rows of fee_units and transaction_count data — no live market data, external enrichment, or predictive analytics are involved. Prefer alternatives if you need real-time fee lookups, predictions, or datasets larger than 200 rows.

## Known failure modes

- Fewer than 1 or more than 200 rows supplied — request rejected
- row_id missing or exceeding 80 characters — validation error
- date field not matching YYYY-MM-DD pattern — schema rejection
- fee_units or transaction_count outside ±1,000,000,000,000 range — validation error
- Mismatched row_ids between primary and secondary datasets may reduce comparison coverage
- Payment of 0.01 USDC not completed — request blocked by x402 paywall

## How this service works

Transaction fee observations — Record quality audit + Keyed dataset comparison: Record quality audit + Keyed dataset comparison for supplied transaction fee observations records (fee_units, transaction_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 analytical reports: (1) a record quality audit covering issues such as nulls, out-of-range values, and malformed entries across the supplied fee rows; (2) a keyed dataset comparison report identifying differences between the primary and secondary datasets matched by row_id, including value-level discrepancies in fee_units and transaction_count. No external lookups or predictions are made; analysis is performed locally on the supplied data only.
