envelope and schemas

Same card as LeetCode. PLATFORM = "gfg". Schema category is fundamentals. CodeTrace’s fetchCard currently tags GFG dsa. The bucket on /profile follows the client.

Try it: playground, docs, sample tashif_ahmad_khan/profile. Placeholder handle in the HTML is demo.

No body, no auth. Path param is username.

Heatmap query: view=all|last_365|year plus year. Deprecated aliases range=all|last365days|year and unused month still parse. Prefer view.

SVG query: theme=dark|light, exclude comma-separated topic names.

GET /tashif_ahmad_khan/stats HTTP/1.1
Host: gfg-stats.tashif.codes

GET /tashif_ahmad_khan/heatmap?view=last_365 HTTP/1.1
Host: gfg-stats.tashif.codes

Server-side upstream input (the browser never sends this):

GET https://authapi.geeksforgeeks.org/api-get/user-profile-info/?handle={username}&article_count=false&redirect=true HTTP/1.1

POST https://practiceapi.geeksforgeeks.org/api/v1/user/problems/submissions/ HTTP/1.1
Content-Type: application/json

{"handle":"tashif_ahmad_khan","requestType":"","year":"","month":""}

  "cached": false,
  "data": {}
}

Older clients still see flattened totalProblemsSolved, School, Basic, Easy, Medium, Hard next to data.

Profile: displayName from info.fullName, username from userName, avatar from profilePicture, institution from institute.

Stats byDifficulty is the reason the shared dict is not three LeetCode fields:

{
  "totalSolved": 412,
  "totalQuestions": null,
  "acceptanceRate": null,
  "byDifficulty": {
    "school": 10,
    "basic": 40,
    "easy": 120,
    "medium": 180,
    "hard": 62
  },
  "topicAnalysis": [
    { "topic": "Arrays", "count": 80 }
  ]
}

Contests and rating exist so CodeTrace can loop six paths. Expect empty history / null rating, HTTP 200, not 404.

Heatmap is synthesized from user_subtime on solved problems. There is no native GFG calendar. created_date drives which years get fetched.

Badges: empty list, badgesCount=0 on summary.

SVG: image/svg+xml, 24h cache.

Deprecated alias GET /{username}/solved-problems returns the stats envelope.

Missing user: HTTP 404 User '{handle}' not found on GeeksForGeeks when authapi says so.
