Extract and verify structured evidence from exactly one authorized artifact, prior SITEBORNE upload, or public document URL. Use when: the source of truth is a PDF or supported image and the desired result is evidence JSON. Do not use when: a webpage alone is sufficient (use siteborne_retrieve_verified_web_context), company-wide public evidence is needed (use siteborne_build_company_evidence_graph), or an existing agent response needs evaluation (use siteborne_verify_agent_output). Parameters: provide exactly one reference mode: artifact_reference (an authorized stored artifact), upload_reference (a prior SITEBORNE upload handle, not document bytes) or document_url (a public URL, no credentials). ocr_permission must be true before image-based content is read by OCR, and OCR pages bill at the OCR tier; extraction_request.extract_tables and table_extraction_request request table extraction, and pages with tables bill at the table tier; declared_page_count and page_range are bounded by the page limit below; maximum_authorized_price only constrains payment. Behavior: open-world: a paid request may read governed artifact storage or fetch a public document URL, calls the document provider, and persists payment, audit, job and Workflow state; an unpaid request returns payment_required; a repeated identical request with the same payment is replay-protected and is not charged twice. This service is currently production-disabled and rejects execution. Economics: upto pricing: the payment challenge authorizes a maximum of $0.19 USD per job; the actual charge is measured per processed page (native-text $0.0098, OCR $0.0156, table $0.0238 per page, the highest applicable tier per page) and never exceeds the authorization. The authorization is a ceiling, not the charge. Documents are limited to 10 pages per job. Failure: schema-invalid input is rejected before any payment challenge; a document over the page limit, an unreadable or encrypted document, or an unavailable provider returns a structured MCP error. Returns: extracted document evidence, integrity/provenance findings, and PCC verification—not an uploaded file.
