How this service works
Return manifest-declared OCI config and layer sizes before an agent pulls an image. Values are registry declarations, not a compressed download or vulnerability measurement. Base mainnet USDC
Output
Returns the manifest-declared OCI image configuration (architecture, OS, entrypoint, env vars) and the size in bytes of each layer as listed in the registry manifest. These are registry-declared values, not compressed download sizes or vulnerability scan results.
Example use cases
Pre-pull image size check
“I need to know how large the ubuntu:22.04 image is before I pull it to my edge node — can you get the declared layer sizes from the manifest without actually downloading it?”
CI pipeline size gating
“In our pipeline, check the manifest-declared total layer size for the image myorg/myapp on the main branch and tell me if any individual layer exceeds 500MB.”
Comparing image weights across tags
“Can you look up the OCI config and layer sizes for python:3.12-slim from the public registry so I can compare it against the full python:3.12 image before choosing which base to use?”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/container/size?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to know a container image's declared layer sizes and OCI config metadata before committing to a pull, especially in bandwidth-constrained or storage-limited environments. Prefer it over actually pulling the image when the goal is pre-flight size inspection, CI/CD gating on image weight, or comparing base image options. Not suitable for vulnerability scanning, compressed download size estimation, or private registry access.
Side effects
- Image repository path does not match expected pattern — returns validation error
- Reference (tag/branch) not found in registry — returns 404-equivalent error
- Registry is private or rate-limits unauthenticated access — returns access denied or timeout
- Malformed image string with uppercase characters or invalid registry format — rejected by schema pattern
- Registry returns an unexpected manifest format — partial or empty layer list returned
