Agent Tools – Bundle Dependency Audit
x402
Agent Tools – Bundle Dependency Audit is a paid API for AI agents from agents.crowdspark.me, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-31).
Audits an npm (package.json) or PyPI (requirements.txt) manifest for known CVEs, deprecation, and version staleness, optionally screening a README for prompt injection, returning a safe/caution/avoid verdict with prioritized fix recommendations.

How this service works
Pay-per-call utilities for AI agents over x402, USDC on Base.
Output
A JSON object containing: a top-level verdict ('safe', 'caution', or 'avoid'); a packages array with per-dependency name, spec, version checked, vulnerability count, and verdict; a summary block with counts of checked, skipped, vulnerable, and over-limit packages; a ranked fixes array with package name, recommended upgrade version, reason, and priority; the detected ecosystem and manifest type; and an optional readme_screen field with prompt injection findings if a README was supplied.
Example use cases
Pre-install security check for npm project
“I'm about to install a third-party npm package into our agent pipeline — can you audit this package.json for known vulnerabilities and tell me whether it's safe, needs caution, or should be avoided? Here's the manifest text.”
PyPI requirements audit before deployment
“We're deploying a Python agent to production tomorrow. Please scan this requirements.txt against known CVEs and deprecation notices and give me a prioritized list of packages I need to upgrade before we ship.”
README prompt injection screening
“A vendor sent us their agent tool — can you check their README for prompt injection attempts and also audit the included package.json for security advisories? I want a verdict before we let it anywhere near our system.”
Technical details
Endpoint
POSThttps://agents.crowdspark.me/v1/bundle/dependency-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a security gate before installing or executing any npm or PyPI project — especially for third-party or user-submitted code. It is purpose-built for agent workflows (x402 micropayment, structured verdict output) and uniquely combines CVE scanning via OSV.dev, deprecation and version staleness checks, and README prompt injection screening in a single call, making it superior to generic package audit tools when the agent needs a machine-readable go/no-go verdict rather than a human-facing report.
Side effects
- Manifest exceeds 200,000 character limit — request rejected
- README exceeds 50,000 character limit — readme field truncated or rejected
- More than 25 dependencies in manifest — excess packages listed in 'skipped' and not checked
- OSV.dev lookup failure for one or more packages — affected packages counted in lookup_failed
- Invalid or unrecognizable manifest format — type detection fails and error returned
- Malformed JSON request body — 400 error returned
- Network timeout reaching OSV.dev advisories backend — partial results or error
