How this service works
Check lightweight metadata for a path in a public GitHub repository at an optional ref. It does not clone or download large file contents. Base mainnet USDC
Output
Returns lightweight metadata about the specified file path in the GitHub repository: whether the path exists, the file type (file or directory), file size in bytes, and the Git SHA/blob hash — without transferring actual file contents.
Example use cases
Verify config file before workflow
“Before I kick off the build pipeline, check whether '.github/workflows/deploy.yml' exists on the 'release' branch of 'myorg/myapp' and tell me its file size.”
Pre-download size check for large asset
“Can you look up the metadata for 'data/training_set.csv' in the 'main' branch of 'ml-team/datasets' so I know how big the file is before I decide whether to download it?”
Confirm schema file presence in open-source library
“Check if 'openapi.yaml' exists at the repo root in the 'stable' branch of 'openapi-tools/spec-generator' — I just need to know if it's there and its SHA, no need to fetch the actual content.”

Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/repo/file-preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm the existence, size, type, or SHA of a file in a public GitHub repository without the overhead of cloning or downloading file contents — ideal for preflight checks before expensive downloads, verifying schema or config file presence in CI/CD pipelines, or checking whether a dependency file exists at a specific branch.
Side effects
- Path does not exist at the given ref — returns not-found or null metadata
- Repository is private or does not exist — access denied or not-found error
- Invalid repository format (not owner/name pattern) — validation error
- Invalid or non-existent ref/branch — not-found or error response
- GitHub API rate limiting or temporary unavailability — upstream error
