CertScore TypeScript SDK

Official TypeScript/JavaScript SDK for the CertScore public API, Pulse API, and website risk-signal workflows.

CertScore outputs are automated public-web observations for review. They are not legal advice, certification, or a compliance determination. Always review the underlying evidence and consult qualified experts where appropriate.

Status

The SDK is published as @certscore/sdk on npm. Use version 0.2.6 or newer for typed no-account allowance and higher-volume support guidance, completed-limited no-go results, API v2 scan timing fields, and client attribution headers. See the npm package and SDK source.

npm install @certscore/sdk

By default the SDK identifies its requests with X-CertScore-Client: sdk. The optional clientName setting is intended for trusted integrations that share the SDK runtime with MCP; regular SDK consumers should keep the default.

Completed no-go scans resolve normally with status: "completed_limited", resultDisposition: "no_go", and a typed noGo object. The object carries a stable reason, customer-safe explanation, target-site or scanner-limitation attribution through limitationKind, retry guidance, and a bounded evidenceExcerpt when available.

Quick Start

import { CertScoreClient } from "@certscore/sdk";

const client = new CertScoreClient();
const pulse = await client.scan("https://example.com");
console.log(pulse.summary?.score, pulse.links?.fullReportUrl);

Resource Clients

New integrations should prefer the resource-oriented API v2 clients for scan, status, finding, pre-consent cookie/tracker table, domain latest, and Pulse projection workflows.

import { CertScoreClient } from "@certscore/sdk";

const certscore = new CertScoreClient({
  apiKey: process.env.CERTSCORE_API_KEY
});

const created = await certscore.scans.create("https://example.com", {
  freshness: "latest",
  scanFrom: "eu_ie"
});

const completed = await certscore.scans.wait(created);
const scanId = completed.scanId;

const status = await certscore.scans.status(scanId);
const diagnostics = await certscore.scans.diagnostics(scanId);
const findings = await certscore.findings.list(scanId);
const preConsentTable = await certscore.scans.preConsentCookiesTrackers(scanId);
const firstFinding = findings.findings[0]
  ? await certscore.findings.get(scanId, findings.findings[0].id)
  : null;
const explanation = firstFinding
  ? await certscore.findings.explain(scanId, firstFinding.id)
  : null;
const pulseProjection = await certscore.pulse.get(scanId);
const pulseEvidence = await certscore.pulse.evidence(scanId);
const latestDomainScan = await certscore.domains.latest("example.com");
const latestPreConsentTable = await certscore.domains.latestPreConsentCookiesTrackers("example.com");

console.log(status.status, diagnostics.totalWallMs, diagnostics.policyDiscovery.phaseWallMs, preConsentTable.summary.rowCount, explanation?.title, pulseProjection.disclaimer, pulseEvidence.type, latestDomainScan.scan?.scanId, latestPreConsentTable.rows.length);

certscore.scans.get(), certscore.scans.status(), and certscore.scans.wait() expose scan timing where the API has enough evidence:

• startedAt
• completedAt
• scanTimeSeconds

scanTimeSeconds is null when timing is unavailable or incomplete. Client code should not coerce that value to 0; reserve 0 only for an explicit numeric API value.

Available resource clients:

• certscore.scans.create()
• certscore.scans.diagnostics()
• certscore.scans.get()
• certscore.scans.preConsentCookiesTrackers()
• certscore.scans.status()
• certscore.scans.wait()
• certscore.findings.list()
• certscore.findings.get()
• certscore.findings.explain()
• certscore.pulse.get()
• certscore.pulse.evidence()
• certscore.domains.latest()
• certscore.domains.latestPreConsentCookiesTrackers()
• certscore.scan()

Cookies & Trackers (Pre-consent)

Use the API v2 resource client when you need the public report table as JSON instead of parsing report HTML or Pulse prose.

const table = await certscore.scans.preConsentCookiesTrackers(scanId);

const grouped = new Map<string, typeof table.rows>();
for (const row of table.rows) {
  const key = [row.vendor, row.purpose, row.host].join("|");
  grouped.set(key, [...(grouped.get(key) ?? []), row]);
}

const latestTable = await certscore.domains.latestPreConsentCookiesTrackers("example.com");
console.log(grouped.size, latestTable.summary.rowCount);

The response is a public-safe report projection. It does not include cookie values, raw request bodies, full request URLs, sensitive query strings, or internal scanner artifacts. Server-side filters are intentionally deferred in the initial version; group or filter the returned table client-side by kind, priority, party, vendor, purpose, or host.

Async Lifecycle

scan() calls /api/v1/pulse with wait=60. If CertScore returns HTTP 202, the SDK polls the returned statusUrl or nextCheckUrl. It honors Retry-After on pending or throttled responses.

import { CertScoreClient, CertScoreTimeoutError } from "@certscore/sdk";

const client = new CertScoreClient();

try {
  const pulse = await client.scan("https://example.com", {
    detail: "standard",
    maxWaitMs: 300_000,
    // Omit for adaptive 1s → 2s → 5s polling; set explicitly for a fixed interval.
    onStatusUpdate(status) {
      console.log("Pulse status:", status.status, status.phase);
    }
  });

  if (pulse.scanStatus === "completed" || pulse.scanStatus === "completed_limited") {
    console.log("Result:", pulse.summary?.headline);
  }
} catch (error) {
  if (error instanceof CertScoreTimeoutError) {
    console.log("Resume later with:", error.jobId, error.scanId);
  } else {
    throw error;
  }
}

Durable scanId Pattern

scanId is the durable audit/cache handle. scan_id may appear in API responses as a compatibility alias, but new integrations should store scanId.

const pulse = await client.scan("https://example.com");
const scanId = pulse.scanId;

await appDb.pulseScans.upsert({
  domain: "example.com",
  scanId,
  reportUrl: pulse.links?.fullReportUrl
});

// Later:
const cachedPulse = await client.getScan(scanId!, { detail: "full" });

Use the full report URL for human review:

console.log(`https://certscore.ai/scan/${scanId}`);

Error Handling

import {
  CertScoreApiError,
  CertScoreClient,
  CertScoreScanFailedError,
  CertScoreTimeoutError,
  InvalidUrlError,
  ThrottledError
} from "@certscore/sdk";

const client = new CertScoreClient();

try {
  await client.scan("https://example.com", { freshness: "refresh" });
} catch (error) {
  if (error instanceof InvalidUrlError) {
    console.error("Invalid URL:", error.message);
  } else if (error instanceof ThrottledError) {
    console.error("Retry after seconds:", error.retryAfterSeconds);
  } else if (error instanceof CertScoreTimeoutError) {
    console.error("Timed out; resume with:", error.jobId, error.scanId);
  } else if (error instanceof CertScoreScanFailedError) {
    console.error("Scan ended before completion:", error.jobId, error.scanId);
  } else if (error instanceof CertScoreApiError) {
    console.error("API error:", error.status, error.code, error.responseBody);
  } else {
    throw error;
  }
}

Markdown Output

Markdown is useful for agent or human-facing summaries.

const markdown = await client.scan("https://example.com", {
  format: "markdown",
  detail: "standard"
});

console.log(markdown);

Submit Without Polling

const job = await client.submitScan("https://example.com", {
  detail: "tiny"
});

console.log(job.status, job.jobId, job.scanId, job.statusUrl);

CI/CD Example

Example GitHub Actions workflow:

name: CertScore Pulse

on:
  deployment_status:

jobs:
  pulse:
    if: github.event.deployment_status.state == 'success'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 22
      - run: node scripts/certscore-pulse-check.mjs
        env:
          TARGET_URL: https://example.com

Example scripts/certscore-pulse-check.mjs:

import { CertScoreClient } from "@certscore/sdk";

const client = new CertScoreClient();
const pulse = await client.scan(process.env.TARGET_URL, {
  detail: "standard"
});

const criticalFindings = (pulse.topFindings ?? []).filter(
  (finding) => finding.criticality === "critical"
);

if (criticalFindings.length > 0) {
  console.error("CertScore surfaced critical automated review signals:");
  for (const finding of criticalFindings) {
    console.error(`- ${finding.label ?? finding.id}`);
  }
  process.exit(1);
}

console.log("No critical automated review signals were surfaced in this Pulse.");

This CI example fails only on critical automated review signals surfaced by CertScore. It does not make a legal or compliance conclusion. CertScore provides automated public-web observations for review, not legal advice, certification, or a compliance determination.

API Notes

• detail supports tiny, quick, standard, and full; quick is an alias for tiny.
• format supports json and markdown.
• freshness supports latest and refresh.
• wait accepts 0 to 80 seconds and only controls the current HTTP request hold window.
• HTTP 202 and 429 may include Retry-After; the SDK uses it for polling/retry timing.
• Terminal usable statuses are completed and completed_limited.
• Terminal edge statuses include failed, expired, and rate_limited.
