Quartermaster Structured JSON Extraction

Choose this endpoint when you need to transform unstructured web pages or raw text into typed, schema-defined JSON objects. Ideal when you already know the exact output shape you want and want extraction guided by your schema. Prefer this over generic scrapers when field-level structure matters, and over LLM prompting alone when you need reliable, validated JSON output conforming to a specific contract.

• URL is inaccessible or returns non-200 — extraction cannot proceed
• Supplied JSON Schema is malformed or invalid — returns schema parse error
• Requested fields are not present in the source content — returns null or missing fields
• Source content is too large or complex for extraction — may return partial results
• Both url and text omitted — missing required input error
• Schema describes a shape incompatible with source content — best-effort or empty result
