One authorization call on your server.

Private Beta package status

@accessverdict/sdk v0.1.0 is implemented and build-ready. Public npm publication remains a deliberate release step.

Install

pnpm add @accessverdict/sdk

Verify a wallet

import { createAccessVerdictClient } from "@accessverdict/sdk";

const accessVerdict = createAccessVerdictClient({
  apiKey: process.env.ACCESSVERDICT_API_KEY!,
});

const result = await accessVerdict.verify({
  policyId: process.env.ACCESSVERDICT_POLICY_ID!,
  wallet: "0x0000000000000000000000000000000000000001",
});

The SDK returns the same allowed, denied and error model as the REST API.

Treat denial and infrastructure failure differently

if (result.status === "error") {
  return Response.json({ error: "authorization_unavailable" }, { status: 503 });
}
if (!result.allowed) {
  return Response.json({ error: "forbidden" }, { status: 403 });
}

Fail closed when verification is unavailable, but do not mislabel infrastructure failure as a normal policy denial.

Keep AccessVerdict secrets server-side

Never put av_test_... or av_live_... keys in browser JavaScript, localStorage, extension bundles or NEXT_PUBLIC_* variables.
