# The Stall — Image Detection (IntuiTek x402)

> The Stall — Image Detection (IntuiTek x402) is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-14).

Analyzes a publicly accessible image URL and returns detected objects, features, or content classifications found in the image

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability the-stall-image-detection-intuitek-x402-92ca46c8
```

Example prompt: Can you tell me what objects and content are detected in this image — https://example.com/photo.jpg — I want to know what's in it?

## When to prefer this

Use this endpoint when you need quick, pay-per-call image object detection or content classification without API keys or account setup. It is ideal for agentic workflows where you have a public image URL and need to detect or identify content in it on a one-off basis, paying micro-amounts per call in USDC on Base. Prefer this over traditional vision APIs when you want frictionless x402 micropayment access with no subscription.

## Known failure modes

- Image URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the image
- URL points to a non-image resource (HTML page, PDF, etc.) — detection fails or returns empty results
- Image format is unsupported — error or empty detection response
- Payment of $0.04 USDC on Base mainnet not fulfilled — 402 response requiring x402 payment
- Malformed or missing 'url' query parameter — validation error returned
- Image too large or times out during fetch — timeout or size error

## How this service works

Detects the true image format of any URL via magic byte inspection — works even when the file extension or Content-Type header lies (common with proxied or CDN-hosted images). Returns: format (png/jpeg/gif/webp/avif/bmp/tiff/svg/ico/unknown), detected MIME type, whether Content-Type header matches, file size (bytes), and pixel dimensions for PNG and JPEG. No API key required. $0.050/call.

## Output

A structured response describing detected objects, labels, or classifications found in the provided image, potentially including confidence scores and bounding regions or categories identified by the vision model.
