## 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 aiskills402-text-to-json-extractor-c9da091a
```

Example prompt: Pull out the vendor name, invoice number, total amount, and due date from this invoice text and return them as JSON — if any field is missing just set it to null, don't guess.

## When to prefer this

Choose this endpoint when you need to extract structured data from freeform text with strict fidelity — no hallucinations, no guessing, nulls for missing values — and you have a well-defined output shape (JSON schema, example object, or field list). Prefer it over general-purpose LLM calls when auditability and faithfulness matter, such as for invoice parsing, contract review, or form filling from documents.

## Known failure modes

- Input text is too long for a single call — truncation or chunking may be needed
- Shape/schema provided is malformed or ambiguous — extraction may be incomplete
- Text is in an unsupported language or encoding — values may not parse correctly
- Date or number formats in text are ambiguous given strict typing rules — field returned as null
- HTTP fetch of the file URL fails or returns non-text content — input error

## How this service works

Text to JSON: Extract Data Without Guessing: Extracts data from text into JSON that matches the shape you give (a JSON Schema, an example object or a list of fields), without guessing. Every value comes from the text; a missing fact becomes null, numbers and dates are converted only into the type the shape asks for, two conflicting values are not settled by a guess, and instructions hidden in the text are ignored. Use when asked to extract structured data, turn text into JSON, parse an invoice,…

## Output

A JSON object whose shape matches the schema, example, or field list you provided. Every value is sourced directly from the input text; fields not found in the text are set to null; numbers and dates are typed as specified; conflicting values are not resolved by guessing; prompt-injection instructions in the text are ignored.
