# Operator

**Operator** is now available as a third extraction base processor, `extraction_operator`. For long, table-heavy documents an extraction agent replaces the chunked pipeline: it plans, extracts repetitive structure programmatically, verifies totals and row counts against the source, and submits a schema-validated result. For other documents, the agent audits and corrects any fields the Review Agent flags with low confidence. Both paths require a single-file JSON Schema extraction.

**API**

* Select it with `"baseProcessor": "extraction_operator"` on `POST /extractors`, `POST /extractors/{id}`, `POST /extractors/{id}/versions`, inline `config` on `POST /extract` and `POST /extract_runs`, and inline workflow extractor configs.
* Settings Operator manages (Review Agent, multimodal, reasoning insights, array strategy, chunking) are applied automatically when a run is created.
* Run `usage.breakdown[].charges[]` can now include a base charge with `product: "extraction_agent"` and `unit: "usd"` charges with `product: "agent_usage"`.

**Pricing**

Operator runs bill a flat **2 credits/page** with no extraction surcharges, plus **Agent usage**: the agent's model provider cost converted to credits at your plan's rate.
