# Hermes Data Repair Plan API

> Hermes Data Repair Plan API is a paid API for AI agents from hermes-counterparty-api.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Analyzes a JSON or CSV dataset and returns a prioritized repair plan identifying data-quality issues like duplicates, missing values, mixed types, and constant fields.

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 hermes-data-repair-plan-api-3ee9b7f1 -d '<json body>'
```

Example prompt: Can you analyze this JSON records array for data quality issues and give me a prioritized repair plan? I want to know about duplicate rows, missing values, constant fields, and mixed types before I load it into production.

## When to prefer this

Choose this endpoint when you need a deterministic, structured audit of a JSON or CSV dataset before downstream use — especially for ETL pipelines, reporting workflows, or agent-driven data cleaning tasks. It is preferable to ad-hoc LLM analysis when you need a reproducible quality score and a machine-readable, prioritized action list. Best for tabular data with clear record boundaries; not suited for unstructured text, images, or nested documents.

## Known failure modes

- Missing required 'input' field returns a validation error
- Body format mismatch (e.g. declaring 'json' but sending 'csv' string) causes parse failure
- Empty records array may return a trivially perfect quality score with no actionable recommendations
- Payment not included or insufficient USDC (x402) results in 402 Payment Required
- Malformed JSON objects in the records array may cause schema inference errors
- Very large payloads may hit hosting-tier (Render free tier) timeout limits

## How this service works

Agent utilities for company research, package maintenance intelligence, dependency vulnerability checks, counterparty availability, SEC company snapshots, OFAC sanctions screening, and deterministic JSON/CSV data-quality work. Company domain intelligence includes a free preview before the paid enrichment call.

## Output

Returns a JSON object containing: a quality_score (0-100), an issues summary (duplicate_rows count, missing_values count, constant_fields list, mixed_type_fields list, identifier_integrity_fields list), a prioritized actions array (each with a code, priority rank, affected_count, and recommendation string), plus a schema_version and sha256 schema_fingerprint.
