How this service works
Batch install-safety preflight for a whole dependency list or parsed manifest (up to 100 packages). Returns a verdict per package plus a blocked / caution / safe summary. Supply-chain indicators, not a guarantee.
Output
Returns per-package verdicts of safe, caution, or block, along with reasons explaining each verdict — such as typosquat similarity to a popular package, known malicious indicators, or non-existence in the registry.
Example use cases
Example prompt
“Before I install these packages, can you scan them for supply-chain risks — check if any of these are typosquats, malicious, or don't even exist: requests, reqeusts, numpy, colourama, flask, flaask.”
Technical details
Endpoint
POSThttps://payai.agentstools.dev/pkg/preflight/batchWhen to prefer
Use this endpoint when you need to vet multiple package names at once for supply-chain safety before installation or CI/CD pipeline execution, especially when you suspect typosquatting or want a quick batch risk classification rather than a single-package check.
Side effects
- Batch too large — endpoint may reject or truncate if too many package names are submitted at once
- Unknown registry — if the registry is not supported, packages may return inconclusive results
- Network timeout — upstream registry lookups may time out for large batches
- False negatives — newly malicious or unknown packages may receive a safe verdict if not yet flagged
- Payment failure — x402 payment of $0.15 USDC not completed, request rejected
