An open API service providing security vulnerability metadata for many open source software ecosystems.
This project is part of Ecosyste.ms: Tools and open datasets to support, sustain, and secure critical digital infrastructure.
Documentation for the REST API is available here: https://advisories.ecosyste.ms/docs
The default rate limit for the API is 5000/req per hour based on your IP address, get in contact if you need to increase your rate limit.
An OSV-compatible API is available at /v1 for interoperability with other vulnerability databases and tooling.
Endpoints:
POST /v1/query - Query vulnerabilities by package/ecosystem or PURLPOST /v1/querybatch - Batch query up to 1000 packagesGET /v1/vulns/:id - Get vulnerability by ID (UUID or CVE)Example:
curl -X POST https://advisories.ecosyste.ms/v1/query \
-H "Content-Type: application/json" \
-d '{"package":{"name":"lodash","ecosystem":"npm"}}'
