Migration guides, measurements and tutorials about Google results, AI agents and the APIs in between.
Google closed the Custom Search JSON API to new customers in January 2026 and turns it off on January 1, 2027. Here is the timeline, your options, and a two-line migration.
In August 2026 Google started serving encoded /goto redirect URLs in place of destination links. Parsers that read href directly now see google.com. How to detect it and fix it.
A Google search API built for AI agents: clean JSON or Markdown, official TypeScript/Python/Go SDKs, native LangChain, CrewAI and MCP, and credits that never expire.
Where the law stands in September 2026 (Google v. SerpApi, Reddit v. SerpApi, hiQ, Meta v. Bright Data), what's still unsettled, and the rules SerpKite follows. Not legal advice.
The same Google results page as full JSON, compact JSON and Markdown, and how many LLM tokens each one costs. Estimates on a sample, with the method spelled out.
A minimal LangGraph agent with a Google search tool: define the tool, bind it to a model, wire a ToolNode loop, and keep the token cost down with Markdown output.
Since Google removed &num=100 in September 2025, the top 100 takes ten requests. What that does to rank-tracking costs, and how to price depth fairly.
