General-purpose: your schema defines the domain (invoices, receipts, resumes, product pages, logs, etc.) \u2014 there is no per-document-type specialization. For best accuracy, add a `description` to ambiguous fields (e.g. \"tax rate as a decimal such as 0.0725\") and make optional fields nullable so absent values return null instead of a guess. Accepts text/HTML input (inputType text|html|auto); OCR noise, number/date formats, and detail lines are normalized automatically. Benchmarked 100% schema-valid with ~0.99 field F1 and zero hallucinations across a 10-doc-type corpus (11 items, incl. an adversarial prompt-injection tier), p50 latency ~1.5s.
