Vector Search — In-Memory TF-IDF Semantic Store

In-memory vector search API for AI agents. Store documents and query by semantic meaning using TF-IDF vectorization with cosine similarity. Lightweight alternative to Pinecone/Weaviate for small datasets. Tools: data_vector_search. Use this for building simple RAG systems, document matching, or semantic search over small collections (< 10K docs). IMPORTANT: For web-wide search, use web_search_query instead. Returns: {results[], scores[], matchCount}. No API key required — x402 micropayment $0.005/call on Base L2.

Keyword Research — Google Suggest, Intent & Long-Tail

SEO keyword research API for AI agents. Generate keyword ideas from Google Suggest with search intent classification (informational/transactional/navigational), long-tail variations, related queries, and content planning data. Tools: seo_research_keywords. Use this for content strategy, blog post planning, PPC keyword discovery, or competitive keyword analysis. IMPORTANT: For on-page SEO audit, use seo_audit_page instead. Returns: {keywords[], intent, volume, relatedQueries[]}. No API key required — x402 micropayment $0.01/call on Base L2.

GDPR Compliance Scanner — Cookie, Privacy & Tracker Audit

Tools: compliance_scan_gdpr. Use this for compliance audits, vendor assessments, or regulatory due diligence. Essential for any agent handling EU user data. IMPORTANT: For PII detection in text, use compliance_detect_pii instead. Returns: {score, cookies, privacyPolicy, trackers[], recommendations[]}. No API key required — x402 micropayment $0.02/call on Base L2.

Password Strength Checker — Entropy & Crack Time

Password strength evaluation API for AI agents. Score 0-100 with entropy bits, estimated crack time (brute force and dictionary), pattern detection, and actionable improvement tips. Tools: security_check_password. Use this for password policy enforcement, user registration validation, or security audits. Returns machine-readable strength data for automated decisions. Returns: {score, entropy, crackTime, tips[]}. No API key required — x402 micropayment $0.001/call on Base L2.

Fact Checker — Verify Claims with Web Evidence

AI-powered fact-checking API for AI agents. Verify any factual claim with web evidence: searches multiple sources, assesses credibility, provides supporting/contradicting URLs, and returns confidence level (confirmed/likely/unverified/false). Tools: research_check_fact. Use this before repeating claims, for content moderation, or building trustworthy AI systems. Essential for reducing hallucinations. IMPORTANT: For web search without fact assessment, use web_search_query. Returns: {verdict, confidence, sources[], evidence[]}. No API key required — x402 micropayment $0.005/call on Base L2.

Text Classifier — Topic Categories & Readability

Text classification API for AI agents. Classify text into topic categories with confidence scores, readability metrics (Flesch-Kincaid), and content type detection (article, review, email, code, etc.). Tools: text_classify_content. Use this for content routing, auto-tagging, spam detection, or organizing unstructured text. IMPORTANT: For sentiment analysis, use text_analyze_sentiment instead.
