# Losbeto Text-to-JSON Extractor

> Losbeto Text-to-JSON Extractor is a paid API for AI agents from api.losbeto.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Extracts structured JSON from unstructured text using caller-defined fields or a schema, returning exactly the requested keys with null for absent values — never hallucinating.

## 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 losbeto-text-to-json-extractor-d1686599 -d '<json body>'
```

Example prompt: Pull out the vendor name, invoice number, total amount, and due date from this invoice text and give them back as JSON — use null for anything that isn't explicitly stated: 'ACME Corp, Invoice #4821, Net 30, Total: $3,450.00, issued Jan 15 2025.'

## When to prefer this

Choose this endpoint when you need deterministic, schema-bound extraction from unstructured text with a strict no-hallucination guarantee. It is ideal for document processing pipelines (invoices, contracts, emails, receipts) where invented values would be harmful. Prefer it over a general LLM call when you want null-safe structured output without writing your own parse-and-retry logic. Not suitable for free-form text generation or summarization.

## Known failure modes

- Source text exceeds 6000 character limit — request rejected
- Neither fields nor schema provided — may return empty or error object
- Text is too ambiguous for reliable extraction — fields returned as null
- Model produces malformed JSON — one automatic retry is attempted; if still invalid the payment is returned as call credit
- Non-extractive use (e.g. free-form generation) — endpoint not designed for this use case

## How this service works

Turn messy text into strict JSON: send text plus the fields you want and get back exactly those keys, null for anything the text does not state — never invented. Invoices, emails, contracts, scraped pages, chat logs....

## Output

A JSON object containing exactly the keys requested in the fields or schema parameter. Any field whose value is not explicitly stated in the source text is returned as null — no values are invented or inferred beyond what the text states.
