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 vextorium-structured-data-extraction-7faa3720 -d '<json body>'
```

Example prompt: Extract the fields 'invoice_number', 'total_amount', 'due_date', and 'vendor_name' from this invoice text: 'Invoice #INV-2047 from Acme Corp, dated March 5 2025, total due $1,240.00 by April 1 2025.'

## When to prefer this

Choose this endpoint when you have free-form text (invoices, emails, receipts, messages) and need to extract a specific, predefined set of named fields into structured JSON. It's ideal for document automation pipelines, form pre-filling, and ETL tasks where field names are known in advance. Prefer it over generic LLM calls when you want consistent, schema-aligned output with null-safe field handling and local AI privacy guarantees.

## Known failure modes

- Missing 'texto' or 'campos' in request body returns a validation error
- Empty or very short text may result in all fields returning null
- Ambiguous text may cause incorrect or null extractions for some fields
- Requesting too many fields may reduce extraction accuracy
- Non-JSON bodyType may cause parsing failures if content is malformed

## How this service works

Structured data extraction with local AI: give a text and a list of field names, get a JSON object with those fields (null when absent).

## Output

A JSON object with a 'datos' key containing the requested field names as keys and their extracted values (or null if not found in the text), plus 'modelo' (the local AI model used) and 'campos_encontrados' (count of non-null fields extracted).
