# ETL-D API - LLM Discovery Manual

ETL-D API is a high-performance data cleaning and enrichment service designed for autonomous agents (n8n, Make, LangChain). It transforms "dirty" unstructured inputs into structured, type-safe JSON.

**Base URL:** `https://api.etl-d.net`

## Core Philosophy
1. **Stateless**: No data storage. Input -> Process -> Output.
2. **Determinism**: Same input always yields same output.
3. **Type Safety**: Returns strict Pydantic models.

## Key Capabilities
- **Date Normalization**: Extracts and formats dates to ISO8601.
- **Monetary Cleaning**: Parses currency strings to decimals + currency codes.
- **Contact Parsing**: Splits names, validates emails/phones.
- **Accounting Categorization**: Maps descriptions to GAAP/IFRS categories.

ETL-D is **Locale-Aware**. It resolves ambiguity in dates, numbers, and phones based on context parameters.
