Upload images to img402.dev and get a public URL. Images 1MB or under are free AND permanent — no account, no API key, no payment. Larger images (up to 10MB) are free for 30 days, or permanent for $0.01 USDC via x402. Use when the agent needs a hosted image URL — for sharing in messages, embedding in documents, posting to social platforms, or any context that requires a public link to an image file.

# Image Hosting — img402

Upload an image to [img402.dev](https://img402.dev) and get a public URL. No account, no API key, no config.

**Most uploads are free and permanent.** A median agent screenshot is ~100 KB, well under the 1 MB threshold where free hosting never expires. Reach for a paid tier only when the file is genuinely large.

## Pick a tier

| Upload | Price | Retention | Use when |
|--------|-------|-----------|----------|
| ≤ 1 MB | $0 | **Permanent** | Almost everything — screenshots, diagrams, charts |
| 1–10 MB | $0 | 30 days | Large images you only need short-term |
| Up to 10 MB | $0.01 USDC | **Permanent** | Large images that must outlive the month |

\* Paid permanence is service-life retention. If img402 ever shuts down, there's a 90-day on-site notice before takedown. See [Terms § 2A](https://img402.dev/terms).

Size is never the reason to pay — 10 MB uploads are free. You pay only to keep an image over 1 MB alive past 30 days.

## Quick reference

```bash
# Upload (multipart)
curl -s -X POST https://img402.dev/api/free -F image=@/path/to/image.png

# Response — expiresAt is null for images 1MB and under
# {"url":"https://i.img402.dev/aBcDeFgHiJ.png","id":"aBcDeFgHiJ","contentType":"image/png","sizeBytes":182400,"expiresAt":null}
```

## Workflow

1. **Get image**: Use an existing file, or generate/download one.
2. **Upload**:
   ```bash
   curl -s -X POST https://img402.dev/api/free -F image=@/path/to/image.png
   ```
3. **Check `expiresAt`**: `null` means permanent. A timestamp means the file was over 1 MB and will be deleted then.
4. **Use the URL**: The `url` field is a public CDN link. Embed it wherever needed.

If you want a permanent URL and the file is over 1 MB, either shrink it below 1 MB:

```bash
sips -Z 1600 /path/to/image.png                                  # macOS — scale longest edge to 1600px
convert /path/to/image.png -resize 1600x1600 /path/to/image.png  # ImageMagick
```

…or use the paid flow below.

## Constraints

- **Max size**: 10 MB (every tier)
- **Formats**: PNG, JPEG, GIF, WebP
- **Rate limit**: 100,000 free uploads/day globally, 1,000/day per IP
- **No auth required**

## Paid tier

When you need permanence for a file over 1 MB, use the paid flow. Two steps: pay for an upload token via x402, then upload the image with that token.

```bash
# Step 1: Get an upload token (requires x402 payment)
POST https://img402.dev/api/upload/token   # $0.01 USDC → permanent, up to 10MB
# → {"toke

## Description:

Upload images to img402.dev and return a public URL for sharing, embedding, posting, or other workflows that need a hosted image link.

This skill is ready for commercial/non-commercial use.

## Publisher:

[img402](https://clawhub.ai/user/img402)

### License/Terms of Use:

MIT-0

## Use Case:

Developers, external users, and agents use this skill to upload local image files and return public CDN URLs for messages, documents, social platforms, or other contexts that require a publicly reachable image.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Uploaded images are public and may be permanent, especially files at or under 1 MB.

Mitigation: Review files before upload and do not upload internal screenshots, personal data, secrets, API keys, regulated data, or other content that should not be public.

Risk: Images over 1 MB may require either temporary retention or a paid x402 flow for permanence.

Mitigation: Confirm the required retention before upload; shrink images below 1 MB for free permanent hosting when appropriate, or use the paid flow only when long-term retention is needed.
