# API versions and scope

Use the version in each operation path, even when the product release is called V2.

Documentation index: https://webcite.co/llms.txt
Canonical page: https://webcite.co/api-docs/versions
API origin: https://api.webcite.co
Authentication: x-api-key header. Keep keys on your server.

## Route versions

Most public operations use `/api/v1`. Numeric verification and retained OCR preparation use the `/api/v2` paths listed in this reference. Product release V2.0.0 did not move every endpoint to a new prefix.

The API origin is `https://api.webcite.co`, without a trailing `/api`. Use the full path shown on each reference page.

## Public and account-scoped workflows

This reference covers the API-key-facing operations in the [public OpenAPI](/api-docs/openapi.json). `/api/v2/context` workflows use account scope and separate availability controls. A deployment does not automatically enable graph retrieval, research, generation, or OCR.

See the [V2.0.0 release notes](https://github.com/strategyconnect/webcite-backend/releases/tag/V2.0.0) for product release context. Feature availability still depends on the environment.
