Verify that a cell's citations support its answer

Authorizations

Authorization
string
header
required

Workspace credential issued from the automation console at /automation. Send it as Authorization: Bearer vq_ws_.... This is NOT a Data API key: a vq_key_ credential is refused here and names the other product in the error.

Path Parameters

matterId
string
required

mat_ identifier of the matter to work inside. Everything in this API hangs off a matter, and the matter in the path is what the authorization boundary is checked against. Take it from GET /v1/matters.

matrixId
string
required

mtx_ identifier of the matrix. Take it from the matter's matrix list.

cellId
string
required

cel_ identifier of one cell, which is one document's answer to one question. Take it from GET .../matrices/{matrixId}/cells.

Response

Successful Response

A second opinion on one answer, from a fresh model call.

The cell's own citations were already checked to be literal substrings of the passages they cite before the cell was saved. This asks the different and harder question: taken together, do those passages actually ENTAIL the answer. A quote can be verbatim and still not support the claim built on it.

model is not published. Which model we asked is our choice, on the same standing list as our token counts and our retrieval spend.

cellId
string
required

cel_ identifier of the cell that was verified.

Example:

"cel_9f2c8b1e4a7d43c9b6e0f1a2c3d4e5f6"

verdict
enum<string>
required

supported when the cited passages entail the answer, partially_supported when a meaningful element is missing or vague, unsupported when the passages do not contain what is needed, and contradicted when they assert something inconsistent with it.

Available options:
supported,
partially_supported,
unsupported,
contradicted
Example:

"supported"

explanation
string
required

Why the verifier reached that verdict, in its own words. Written for a lawyer to read, not to be parsed.

Example:

"The cited passage states that liability shall not exceed the fees paid in the preceding twelve months, which is what the answer reports. Nothing in the cited sections qualifies that cap."

confidence
number
required

The verifier's confidence in its own verdict, 0 to 1. Not the same thing as the cell's confidence, which is the extractor's confidence in the answer.

Example:

0.92
