Vaquill AI Research API is one of 26 APIs that [Vaquill AI](https://apis.io/providers/vaquill-ai/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 18 JSON Schema definitions. Tagged areas include Research. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, a changelog, and 18 JSON Schemas.

Asking legal questions and getting grounded, cited answers. This API does NOT stream: an ask answers `202` and you poll the operation, then read the answer off the message it points at. Conversation state is kept here, so you hold a chat id rather than replaying a transcript. Also covers the matter settings behind an answer, the skills you can ask through, and the standalone web-research tools.
