How this service works
Compress an image and verify a vision model still reads it — a signed record anyone can check. GET ?image_url=
Output
A signed certificate record confirming whether the vision model successfully read the compressed image, including the compression result, the model's interpretation, and a tamper-evident signature that third parties can independently verify.
Example use cases
Pre-publish image quality gate
“Before I publish this product image at https://cdn.mystore.com/product42.png, compress it and certify that your house vision model can still read the text and details — give me the signed record.”
OCR survival check for scanned documents
“I have a scanned document at https://files.myapp.com/scan_invoice.jpeg — can you compress it and verify with OCR mode that the text is still legible, and give me a certificate I can attach to the invoice?”
Verify image readability for a specific model
“Run a recon check on https://assets.example.com/chart.webp, compress it, and confirm that gpt-4o can still interpret the chart — I need the signed verification record.”

Endpoint
GEThttps://api.s2ar.dev/x402/v1/certify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both compression and AI-readability validation in a single step with a cryptographically signed output — ideal for audit trails, compliance workflows, or any scenario where you must prove to a third party that a compressed image still passes vision model parsing.
Side effects
- Image URL is unreachable or returns a non-image content type
- Image exceeds the 4 MB size limit
- Unsupported image format (not PNG, JPEG, or WebP)
- Vision model fails to parse even the original image
- Invalid probe mode value (must be recon, ocr, or auto)
- Network timeout fetching the remote image
- Payment not included or insufficient USDC balance
