Github Image Hosting

Upload images to img402.dev for embedding in GitHub PRs, issues, and comments. Images under 1MB are uploaded free (no payment, no auth) and persist for 7 days. Use when the agent needs to share an image in a GitHub context — screenshots, mockups, diagrams, or any visual. Triggers: "screenshot this", "attach an image", "add a screenshot to the PR", "upload this mockup", or any task producing an image for GitHub.

Image Upload for GitHub

Upload an image to img402.dev's free tier and embed the returned URL in GitHub markdown.

Quick reference

# Upload (multipart)
curl -s -X POST https://img402.dev/api/free -F image=@/tmp/screenshot.png

# Response
# {"url":"https://i.img402.dev/aBcDeFgHiJ.png","id":"aBcDeFgHiJ","contentType":"image/png","sizeBytes":182400,"expiresAt":"2026-02-17T..."}

Workflow

Get image: Use an existing file, or capture a screenshot:

screencapture -x /tmp/screenshot.png        # macOS — full screen
screencapture -xw /tmp/screenshot.png       # macOS — frontmost window

Verify size: Must be under 1MB. If larger, resize:

sips -Z 1600 /tmp/screenshot.png  # macOS — scale longest edge to 1600px

Upload:

curl -s -X POST https://img402.dev/api/free -F image=@/tmp/screenshot.png

Embed the returned url in GitHub markdown:

GitHub integration

Use gh CLI to embed images in PRs and issues:

# Add to PR description
gh pr edit --body "$(gh pr view --json body -q .body)

![Screenshot](https://i.img402.dev/aBcDeFgHiJ.png)"

# Add as PR comment
gh pr comment --body "![Screenshot](https://i.img402.dev/aBcDeFgHiJ.png)"

# Add to issue
gh issue comment 123 --body "![Screenshot](https://i.img402.dev/aBcDeFgHiJ.png)"

Constraints

Max size: 1MB
Retention: 7 days — suitable for PR reviews, not permanent docs
Formats: PNG, JPEG, GIF, WebP
Rate limit: 1,000 free uploads/day (global)
No auth required

Tips

Prefer PNG for UI screenshots (sharp text). Use JPEG for photos.
If a screenshot is too large, reduce dimensions with sips -Z 1600 before uploading.
When adding to a PR body or comment, use gh pr comment or gh pr edit with the image markdown.

Paid tier

For permanent images (1 year, 5MB max), use the paid endpoint at $0.01 USDC via x402. See https://img402.dev/blog/paying-x402-apis for details.
