Technical details
Endpoint
GEThttps://api.x402node.dev/image/infoWhen to prefer
Use this endpoint when an AI agent needs to inspect remote image properties without downloading the full file manually, especially for validating uploads, planning responsive srcsets, or checking format compatibility before processing. Prefer this over manual HTTP HEAD requests when you need parsed pixel dimensions and aspect ratio in addition to content-type.
Side effects
- URL is unreachable or returns a non-200 HTTP status — endpoint returns an error indicating fetch failure
- URL points to a non-image resource — returns an error or null type fields
- Image format is unrecognized or corrupted — returns an error or partial metadata
- Request times out due to slow remote server — returns a timeout error
- Malformed or missing URL parameter — returns a validation error
