Overview

FOFA provides asset search — key-based (an invalid account returns HTTP 200 with an error body, verified).

Quick Start

Search (replace YOUR_EMAIL/YOUR_KEY):

curl "https://fofa.info/api/v1/search/all?email=YOUR_EMAIL&key=YOUR_KEY&qbase64=dGVzdA=="
{ "error": true, "errmsg": "[-700] 账号无效" }

Authentication

  • Register at fofa.info → email + key.
  • Send them as query parameters (invalid → 200 + error, verified).

⚠️ Gotcha (verified): an invalid account returns HTTP 200 with error: true — check error.

Rate Limits & Notes

  • Key-based with a free tier (check the docs).
  • Asset/device search.
