Analysis

Cross-Document Analysis

Analyze and cross-reference multiple documents together. Unlike /analyze (single document) or /analyze/batch (many documents independently), this endpoint lets the agent reason across all documents simultaneously.

Use cases:

Validate an invoice against a contract or purchase order
Check that a report’s numbers match a source spreadsheet
Compare terms across multiple agreements
Reconcile data from different sources

Upload 2-5 files and/or provide URLs. Each document gets a label (auto-generated from filename, or you can provide custom labels). The agent can search, read, and compare data across all documents.

Provide a typed schema — each field has a type and description.

Example:

{
  "rates_match": {"type": "boolean", "description": "Do the hourly rates on the invoice match the contract?"},
  "total_valid": {"type": "boolean", "description": "Does the invoice total equal the sum of line items?"},
  "correct_vendor": {"type": "boolean", "description": "Is the vendor name on the invoice the same as the contracting party?"}
}

Pricing: 5 credits/document + 3 credits/page (minimum 10).
