Engineering insights
Tutorials, deep dives, and practical guides for building AI agents with real-time web search.
Perplexity Uses Google Search API: Implications
Perplexity sources results through Google. Search APIs are the infrastructure layer every answer engine depends on. Build your own for $0.03/query.
Product Profitability Stress Testing with Live Data
Stress test product ideas with live search data: PPC doubles, returns spike 15%, competitors enter. Model scenarios instead of spreadsheet guessing.
Project-Scoped MCP Servers vs Global Config
Project-scoped MCP reduces token waste by limiting tools to what the current project needs. Global config wastes 5K-12K tokens on unused schemas.
RAG Search Grounding: Cost vs Quality Tradeoffs
Adding search grounding to RAG improves accuracy 30-50% for time-sensitive queries at $0.005-0.03 per query. When it's worth it and when it's not.
Retrieval Layer Matters More Than Reasoning for Agents
Agent quality depends more on data retrieval than LLM reasoning. A mediocre model with accurate data outperforms a frontier model with stale context.
Scoped Data Beats More Data for AI Agents
Agents with access to everything produce unfocused results. Scoping to 3-5 high-quality sources improves accuracy and reduces token waste.

Scavio vs Tavily vs Brave vs Linkup vs Sonar: full pricing, data richness, and framework integration comparison.
Agent Security Risks in Financial MCP Servers
Financial MCP servers need read-only tokens, confirmation gates, input validation, and audit logging. Never expose write operations.
AI Agent Web Access Is a Production Requirement
Agents without search hallucinate URLs, cite deprecated APIs, and show wrong pricing. Search costs $30-100/mo, hallucinations cost $6K+/mo.
AI Bot Blocking Landscape: Status Report May 2026
35%+ of top 1M websites block AI bots. Cloudflare, Akamai, and GoDaddy partnership driving adoption. Impact on developers.
AI Overview Trust Layer for Agent Outputs
AI Overviews sometimes cite incorrect sources. A verification layer between search and agent actions costs $0.005-0.01/query.
Clay Is Overkill for Local Business Leads
Clay starts at $185/mo for B2B SaaS prospecting. Local lead gen needs Google Maps data at $5-15/mo via search API.

Cold Email: Data Quality Beats Copywriting
Lead enrichment via SERP data improves cold email response rates 3-5x. Data quality matters more than copy optimization.
Cold Email SERP Audit Personalization Trick
Run a mini SEO audit per prospect via search API. Specific findings as email openers get 8-15% reply rates vs 1-3% generic.
Common Crawl vs Real-Time Search API: When to Use Each
Common Crawl: petabytes free, 2-8 weeks stale. Real-time APIs: $0.005/query, current. Use cases and hybrid architecture.
Cross-Platform Brand Monitoring from One API
Monitor brand across Google, TikTok, Reddit, and YouTube from one API for $3-15/mo instead of $289-609/mo in separate tools.
CSS Selector Maintenance: The Hidden Cost Spiral
20 scraping targets break ~80 times/year. At 1.5 hours per fix, that is $9,000/year in maintenance vs $600/year for API access.
Custom API MCP Beats SaaS Tool Switching
Build an MCP server from your own API in 30-60 minutes. Eliminates tab-switching tax across 5-10 SaaS tools.
Why Free Search API Tiers Keep Shrinking
Brave, Google, Tavily, and SerpAPI all reduced free tiers. AI agents consume 10-100x human query rates, breaking the economics.
