Is FOFA free, and does it need an API key?

Every registered FOFA account has an API key, but a free account returns limited results. F-points, earned by submitting unrecorded assets or bought, unlock bigger queries and exports.

How to get a FOFA API key

  1. Register an account at en.fofa.info.
  2. Open your personal centre and copy the API key.
  3. Since late 2023 the API needs only the key; the old email-plus-key format still works.

Send it as ?key=YOUR_KEY&qbase64=BASE64_QUERY

Overview & Architectural Role

FOFA provides programmatic access to search engine for internet connected assets and devices. Delivered over secure HTTPS protocols, it exposes structured endpoints designed to integrate cleanly into modern frontend frameworks, backend microservices, and automated data pipelines without requiring local database provisioning.

Who it is built for

Engineers building web dashboards, mobile applications, CLI utilities, or background cron workers in need of reliable security data feeds.

Architectural Advantage

Consuming FOFA removes the operational overhead of running custom scrapers, orchestrating headless browser fleets, or manually seeding and maintaining a local database. Instead of reverse-engineering volatile DOM layouts or dealing with anti-bot IP blocks, your application connects directly to a standardized JSON interface designed for backend ingestion with consistent schema schemas. Dedicated authentication ensures rate quotas and credential tracking per project environment.

Core Use Cases & Architecture Ideas

Practical real-world patterns for integrating FOFA into software systems.

Automated SaaS Feature Integration

Embed data and functionality from FOFA directly into application onboarding, profile enrichment, or reporting dashboards.

Architecture: Backend service worker fetches FOFA during user workflows, caches responses in Redis, and hydrates UI state.

Scheduled Reporting & Monitoring Bot

Periodically extract updates from FOFA to generate daily digests, analytics reports, or Slack notifications.

Architecture: A scheduled GitHub Action or cron worker executes a lightweight script calling FOFA, formatting markdown summaries for stakeholders.

Rapid Prototyping & Hackathon Showcase

Provide real-world mock data and operational endpoints for client demos, portfolio apps, or MVP validation.

Architecture: Static client SPA queries FOFA directly to populate mock dashboards, graphs, and interactive UI states without a custom backend.

Code Implementation Examples

Production-ready starting templates with error handling for FOFA.

// Requires an API key. Check the docs for whether it goes in a header or a query parameter.
// Modern native fetch with error handling
async function callApi() {
  try {
    const response = await fetch('https://en.fofa.info/api/v1/resource', {
      method: 'GET',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      Accept: 'application/json',
    },
    });

    if (!response.ok) {
      throw new Error(`HTTP ${response.status}: ${response.statusText}`);
    }

    const data = await response.json();
    console.log('Response payload:', data);
    return data;
  } catch (error) {
    console.error('API request failed:', error);
    throw error;
  }
}

// callApi();

This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

  }
}

Integration Considerations & Best Practices

Technical factors to keep in mind when integrating FOFA into production environments.

Implement In-Memory or Edge Caching

Avoid triggering rate limits on public feeds by caching response payloads in Redis, Vercel KV, or standard HTTP Cache-Control headers with a 5-to-15 minute TTL.

Shield Credentials in Backend Route Handlers

Never expose private API keys in client-side JavaScript or bundle environments. Proxy requests through a Next.js API route or serverless backend to keep secret keys out of public DevTools inspection.

CORS Proxy Required for Browser Frontend Calls

This API does not send Access-Control-Allow-Origin response headers. Direct fetch() calls from browser JavaScript will fail due to Same-Origin Policy. Route your calls through a server backend or lightweight edge proxy.

Validate HTTP Status Before Parsing JSON

Always inspect response.ok before executing response.json(). Upstream services returning 4xx or 502 Bad Gateway often serve HTML error pages, which cause syntax errors when parsed as JSON.

FOFA — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is the FOFA API free?

Every registered FOFA account has an API key, but a free account returns limited results. F-points, earned by submitting unrecorded assets or bought, unlock bigger queries and exports. Checked on 2026-10-24.

Does FOFA need an API key?

Yes, and it is free: you get one by signing up. Send it as ?key=YOUR_KEY&qbase64=BASE64_QUERY.

How do I get a FOFA API key?

1. Register an account at en.fofa.info. 2. Open your personal centre and copy the API key. 3. Since late 2023 the API needs only the key; the old email-plus-key format still works.

Can I call FOFA from browser JavaScript?

Not directly. FOFA did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.

Is FOFA still working?

Yes, as of 2026-10-24. Our automated check reached FOFA and recorded a 100% reliability score with a median response time of 2014 ms. We re-check on a schedule, and this page updates with the result.
