# Foundry CSV Partition Consistency Validator

> Foundry CSV Partition Consistency Validator is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

Validates and reconciles multiple CSV partitions by checking for key conflicts, duplicate keys, blank keys, and header compatibility across all partitions.

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 foundry-csv-partition-consistency-validator-ab6ae9d2 -d '<json body>'
```

Example prompt: Check these two CSV partitions for consistency — use 'user_id' as the key column — and tell me if there are any duplicate keys, blank keys, header mismatches, or conflicts between the two chunks: [partition 1 CSV text] and [partition 2 CSV text].

## When to prefer this

Choose this endpoint when you need a deterministic, pay-per-request audit of whether 2–5 CSV text partitions are mutually consistent on a shared key column — especially when you need SHA-256 provenance hashes, explicit conflict lists, and header compatibility checks in a single structured JSON response. Prefer this over manual scripts when you need verifiable evidence of data integrity for compliance or pipeline validation purposes.

## Known failure modes

- Missing required field 'key_column' or 'partitions' returns a validation error
- Fewer than 2 or more than 5 partitions causes a schema rejection
- Any single partition string exceeding 12,000 characters is rejected
- Malformed CSV content may result in unexpected parse errors or incomplete analysis
- If evidence is very large, 'evidence_truncated' will be true and results may be partial
- Network or worker errors may return HTTP 5xx with no result body
- Insufficient USDC balance causes payment failure before processing

## How this service works

Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.

## Output

A JSON object containing: overall status (PASS or FAIL), a list of detected conflicts between partitions, total row count across all partitions, count of duplicate keys, count of blank keys, a boolean indicating whether headers are compatible across all partitions, SHA-256 hashes for each input partition, and a flag indicating whether evidence was truncated due to size limits.
