The TypeScript version, typed against the shared contracts package so the shapes cannot drift:

import type { ApiError, AssayReport, CreateAssayRequest } from "@assaylayer/contracts";

const body: CreateAssayRequest = {
  kind: "deep",
  input: { type: "text", text: draft },
  reference: "cms-article-8412",
};

const response = await fetch("https://api.assaylayer.com/v1/assays", {
  method: "POST",
  headers: {
    authorization: `Bearer ${process.env.ASSAYLAYER_API_KEY}`,
    "content-type": "application/json",
  },
  body: JSON.stringify(body),
});

if (!response.ok) {
  const { error } = (await response.json()) as ApiError;
  throw new Error(`${error.code}: ${error.message}`);
}

const report = (await response.json()) as AssayReport;

// Origin established beats origin inferred: check this before the score.
if (report.summary?.signal === "provenance") {
  await markAsDisclosed(report.id);
}
