How this service works
Agent utilities for company research, package maintenance intelligence, dependency vulnerability checks, counterparty availability, SEC company snapshots, OFAC sanctions screening, and deterministic JSON/CSV data-quality work. Company domain intelligence includes a free preview before the paid enrichment call.
Output
Returns a JSON object with a 'vulnerable' boolean, a 'vulnerability_count' integer, a 'vulnerabilities' array (with CVE/advisory details if any), a 'warnings' array, the original query echoed back, and the OSV.dev API source reference. If no vulnerabilities are found, 'vulnerable' is false and both arrays are empty.
Example use cases
Pre-deploy security audit for Node.js app
“Before we ship this release, can you check if express version 4.18.2 in npm has any known vulnerabilities I should worry about?”
Python package CVE scan in CI pipeline
“We're using requests version 2.28.1 from PyPI — can you check the OSV database to see if it has any reported security issues?”
Maven dependency vetting for enterprise project
“Can you check if org.apache.logging.log4j:log4j-core version 2.14.1 in the Maven ecosystem has any known vulnerabilities? We need to know before approving this dependency.”
Technical details
Endpoint
POSThttps://hermes-counterparty-api.onrender.com/v1/dependency-vulnerability-checkWhen to prefer
Choose this endpoint when you need a quick, deterministic, per-package vulnerability lookup against the OSV.dev database with a structured JSON response, especially in agent workflows that require pay-per-call billing via x402 USDC. Prefer it over manual OSV.dev queries when integrating security checks into automated pipelines, CI/CD agents, or software supply chain audits. It is also useful when you need the result in a clean schema alongside other Hermes commerce intelligence endpoints on the same platform.
Side effects
- Unknown package or version — OSV.dev may return empty results without indicating the package doesn't exist
- Invalid ecosystem name — request may fail or return no results if ecosystem string doesn't match OSV taxonomy (e.g. 'node' instead of 'npm')
- OSV.dev API downtime — upstream provider unavailable causing the endpoint to error
- Partial version matching — OSV may not match if version string format doesn't exactly match their records
- Rate limiting or payment failure — x402 payment of 0.005 USDC must succeed before the request is processed
