ForgeMesh File Checksum Verifier
x402
ForgeMesh File Checksum Verifier is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).
Fetches any public file URL (up to 50MB) and returns its SHA-256, SHA-512, SHA-1, or MD5 hex digest so agents can verify a download matches its published checksum before trusting it.

How this service works
File checksum API: fetch any public file URL (up to 50MB) and return its SHA-256/SHA-512/SHA-1/MD5 hex digest — verify a download matches its published checksum BEFORE trusting it. Supply-chain safety for agents installing packages, models, and binaries. File is hashed in memory and discarded.
Output
A hex-encoded cryptographic digest (SHA-256 by default, or SHA-1/SHA-512/MD5 if specified) of the fetched file, confirming or allowing comparison against a known published checksum. The file is hashed in-memory and discarded after computation.
Example use cases
Example prompt
“Before we install that PyTorch wheel, can you verify that https://files.pythonhosted.org/packages/torch-2.3.0-cp310-linux.whl has a SHA-256 hash matching a9f3c2e1 — fetch the file and return the full hex digest so I can compare?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/verify-file-checksumWhen to prefer
Use this endpoint when an AI agent needs to verify a remote file's integrity before installing, executing, or trusting it — especially for packages, model weights, or binaries downloaded as part of an automated workflow. Prefer this over computing hashes locally when the agent cannot download the file directly or needs a neutral third-party hash computation.
Side effects
- File URL is not publicly accessible or returns a non-200 status — API returns an error
- File exceeds the 50MB size limit — API returns a size limit error
- Unsupported algorithm specified — API returns a validation error
- Network timeout fetching the remote file — API returns a timeout error
- Invalid or malformed URL provided — API returns a bad request error
