# Evaluation Run Imports — Record Key Uniqueness Validator

> Evaluation Run Imports — Record Key Uniqueness Validator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Validates that all record keys in an evaluation run CSV import are unique, checking up to 1000 rows against a declared table contract.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 evaluation-run-imports-record-key-uniqueness-validator-30349719 -d '<json body>'
```

Example prompt: Can you check this evaluation run CSV for duplicate record keys? The file uses comma delimiters and has columns evaluation_id, evaluated_on, dataset_id, correct_count, example_count — I need to make sure every evaluation_id is unique before I import it.

## When to prefer this

Choose this endpoint when you need a fast, inexpensive ($0.01 USDC) pre-import uniqueness check specifically for evaluation run CSV data with up to 1000 rows. It is purpose-built for evaluation run import table contracts, supports quoted cells, configurable delimiters, allowed category constraints, and returns a structured key uniqueness report — making it ideal for automated data pipeline validation gates before loading evaluation results into downstream systems.

## Known failure modes

- CSV exceeds 1000 row limit — partial or error response
- CSV string is empty or malformed — validation error returned
- Delimiter mismatch causes incorrect parsing — false positives or missed duplicates
- Cell content exceeds max_cell_length — truncation or rejection
- Allowed categories list mismatch causes category-related validation failures
- CSV exceeds 100,000 character maxLength — rejected with size error

## How this service works

Evaluation run imports — Record key uniqueness: Record key uniqueness for Evaluation run imports. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV record key uniqueness report.

## Output

A CSV record key uniqueness report indicating whether all record keys in the submitted evaluation run CSV are unique, identifying any duplicate keys found across up to 1000 rows, based on the declared table contract and configured delimiter and allowed categories.
