GET API routes

All routes return JSON and require the username query parameter. Base URL: https://your-instance.vercel.app

GET/api/user?username=<user>

Full profile: question counts by difficulty, profile info (ranking, reputation, avatar), submit stats, recent submissions, and computed streak.

curl "https://your-instance.vercel.app/api/user?username=reinanbr"

GET/api/streak?username=<user>

Current streak and longest daily-submission streak, computed from the submission calendar.

{
  "totalSubmissions": 10,
  "currentStreak": 0,
  "longestStreak": 2
}

GET/api/stats

Accepted vs. total submissions, grouped by difficulty (Easy/Medium/Hard/All).

GET/api/submissions

Recent submissions (title, language, status, timestamp). Accepts an optional &limit=.

Shields.io integration

/api/shields returns the JSON schema that shields.io's dynamic endpoint badge expects — useful if you already use shields.io elsewhere in your README and want a consistent look.

GET/api/shields?username=<user>&stat=<stat>

Parameter	Required	Description
`username`	yes	LeetCode username
`stat`	no	`solved` (default), `easy`, `medium`, `hard`, `ranking`, `reputation`, `contributions`, `streak`, `longeststreak`, or `totalsubmissions`
`label`	no	Overrides the left-hand label text
`color`	no	Overrides the color (shields.io name or hex)

https://img.shields.io/endpoint?url=https://your-instance.vercel.app/api/shields?username=reinanbr%26stat=solved

In Markdown:

SVG badges (no shields.io dependency)

/api/badge renders the SVG directly — simpler to embed, with no extra round trip through shields.io.

GET/api/badge?username=<user>&stat=<stat>

Parameter	Required	Description
`username`	yes	LeetCode username
`stat`	no	`solved` (default), `easy`, `medium`, `hard`, `ranking`, `reputation`, `contributions`, `streak`, `longeststreak`, `totalsubmissions`
`label`	no	Overrides the left-hand label text
`color`	no	Shields.io color name (`brightgreen`, `orange`, `blue`...) or hex (`#ff69b4`)
`style`	no	`flat` (default) or `flat-square`

Errors & caching

JSON routes (`/api/user`, `/api/stats`...)

Missing username or a user that doesn't exist → 400/404 with { "error": "..." }. Cache: s-maxage=300.

`/api/shields` and `/api/badge`

Never return an HTTP error — always 200 with a red error badge/JSON, so the embedded README image never breaks. Cache: s-maxage=3600 on success.
