# Software & APIs

> Compare and use software, APIs, MCP servers, and automations.

Use Darwin Search when you need an executable software capability rather than a general product category.

## Describe the capability

Include the required input, output, integration constraints, security needs, and acceptance test.

```text theme={null}
OCR API for handwritten forms that returns tables as structured JSON and supports server-side batch processing.
```

## Compare results

Review supported inputs, output guarantees, protocols, availability, pricing, access requirements, and the evidence in `whyMatched`. Keep the returned order canonical.

## Continue to Act

Pass the selected `capabilityId` and `capabilityRevision` to Act. Connection or credential steps can pause the Action without exposing provider secrets to the client.
