How this service works
Pay-per-call services for AI agents over x402 (USDC on Base).
Output
Returns a numeric security score (0-100), a verdict (e.g. 'safe', 'caution', 'unsafe'), a list of reasons, a recommendation string, known vulnerabilities with IDs/severities/fix versions, and package facts including license, latest version, and weekly downloads.
Example use cases
Pre-install dependency security audit
“Before I add requests 2.28.0 from PyPI to my app, can you check if it has any known vulnerabilities or if there's a newer version I should use instead?”
CI pipeline package gating
“Check whether the npm package minimist at version 1.2.5 is safe enough to ship — give me the security score and any critical issues I should know about.”
Open source license compliance check
“I need to know the license and security status of the PyPI package numpy latest version — is it safe and what license does it use?”
Technical details
Endpoint
POSThttps://tolca.tonbot.ca/v1/pkg-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically vet a specific npm or PyPI package before installation, in a CI/CD pipeline, or during dependency auditing workflows. It is preferable over manual CVE searches when you need a machine-readable score and verdict in a single call, and when you want both vulnerability data and license/version freshness combined. Best suited for agents automating software supply chain decisions at $0.02 per check.
Side effects
- Package not found in the specified ecosystem — returns error or empty result
- Unsupported ecosystem value (only 'npm' and 'PyPI' are accepted)
- Invalid or malformed package name — request rejected
- Specified version does not exist — may fall back to latest or return error
- Vulnerability database temporarily unavailable — score may be incomplete
- Payment failure over x402 — call not processed
