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.
Example use cases
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?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/image-detectWhen to prefer
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.
Side effects
- 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
