AgentReader Structured Data Extraction

Choose this endpoint when you need to extract structured, schema-validated JSON from arbitrary web content and you already know the exact shape of the output you want. It is ideal over generic scraping APIs when schema conformance is critical — e.g. feeding data directly into a typed database or a strictly-typed downstream service. Prefer it over general-purpose LLM calls when you want guaranteed JSON structure without writing your own extraction prompt engineering. It is especially useful when the source is unstructured prose, mixed HTML, or a public web page that would otherwise require custom parsing logic.

• URL is unreachable or returns non-200 — extraction cannot proceed, error returned
• Caller-provided JSON Schema is malformed or has unsupported constructs — validation error
• Target page requires JavaScript rendering or authentication — content may be incomplete or empty
• Requested schema fields are not present in source content — fields may be null or missing in output
• Input text/HTML is too long for the underlying model context window — truncation or error
• Rate limiting or payment failure via x402 — 402 response with payment details
