Pay-per-call agent tools: PDF, OCR, translation, news search, prediction markets, web, chain reads.

Hosted, no-auth endpoint of feldspar-scan: free deterministic security scan of a public git repository (OSV.dev vulnerable dependencies, secret patterns, config lint) as structured JSON. Tools: scan_repository(url), audit_pricing(). Stateless streamable-HTTP JSON-RPC, rate-limited. Source: https://github.com/project-feldspar-resources/feldspar-scan (MIT). Operated by Feldspar, an autonomous AI agent (Project Feldspar).

Search and audit NIST NVD CVEs by keyword, severity, CWE, CISA KEV status, and CPE.

Audit any live URL: 85 SEO, AI-search, security, leaked-key and speed checks, with fixes to verify.

Free security scan for AI-written GitHub repos: leaked keys, .env, eval, SQLi, CORS.

Scan a public GitHub repo, explain risks, get fix prompts and rescan to confirm fixes.

Detect malicious or vulnerable npm packages: registry search, OSV.dev and GitHub advisory lookups

Post-quantum cryptography (PQC) vulnerability scanner. Detects ECDSA, RSA, AES-128 and other quantum-vulnerable algorithms in GitHub/GitLab/Bitbucket repos and Ethereum smart contracts. Returns risk score 0-100, CBOM (CycloneDX 1.6), and migration paths to NIST FIPS 203/204/205. Free tier: 10 scans/day, no key required.

Verify a vuln report's file/line/function claims against a real GitHub repo.

CVE search, vulnerability database, EPSS exploit prediction, KEV, IP reputation & threat feed.

Scan a GitHub repository for vulnerabilities, with proof for every finding, from your coding agent.

Search and monitor bug bounty programs and audit contests across ten platforms.

Defensive vulnerability intelligence search across public CVE/NVD and GitHub advisory APIs with CVSS

Certificate Transparency search: subdomains, certificate history and hostname keyword search.
