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.
Example use cases
Invoice data extraction for accounting
“Extract the vendor name, invoice number, line items, subtotal, tax, and total from this invoice text and return it as JSON — use null if any field isn't mentioned: 'Globex Industries, Invoice #7732, 3x Widget A @ $120, 1x Widget B @ $85, Subtotal $445, Tax $35.60, Total $480.60, Due Feb 28 2025.'”
Email metadata parsing for CRM ingestion
“Parse this email and pull out the sender name, sender email, subject, date sent, and any mentioned meeting date as structured JSON — if a field isn't in the email set it to null: 'From: jane.doe@contoso.com, Subject: Follow-up on Q1 proposal, Sent: Mon Jan 20 2025, Hey team, can we meet on Jan 27?'”
Contract clause extraction for legal review
“Extract the party names, effective date, termination clause, governing law, and payment terms from this contract snippet as JSON with null for anything not stated: 'This Agreement is entered into as of March 1 2025 between Apex LLC and Bravo Inc. Payment is due within 60 days. Governed by the laws of Delaware.'”
Technical details
Endpoint
POSThttps://api.losbeto.xyz/extract?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
