Hey dev.to fam! NapNox here. November 11, 2025—AI's heating up. If you're building bots that guess wrong or output garbage, Google's Gemini drops are your fix. Quick guide with snippets to prototype today. TL;DR: 3 tools that make AI reliable AF. Let's code! #AI #GeminiAPI #DevTools
Tired of AI hallucinations? Gemini API Tools 2025 ground your apps in reality: Maps for locations, File Search for RAG magic, and Structured Outputs for JSON wins. Free tiers, low costs—perfect for indie hackers or teams.
1. Google Maps Grounding: Location Queries That Hit
Pull 250M+ places—no API juggling.
// Node.js quickie
const { GoogleGenerativeAI } = require("@google/generative-ai");
const genAI = new GoogleGenerativeAI("YOUR_KEY");
const model = genAI.getGenerativeModel({
model: "gemini-2.0-pro-exp",
tools: [{ googleMaps: {} }]
});
const result = await model.generateContent("Vibe at best Italian near me?");
console.log(result.response.text()); // Grounded recs + widget!
Remix in AI Studio. Budget: Free quotas. Win: Hyper-local apps like delivery bots.
2. File Search: RAG Without the Grind
Upload files, query semantically—cites included. Free queries!
# Python setup
import google.generativeai as genai
genai.configure(api_key="YOUR_KEY")
# Upload (one-time $0.15/M)
store = genai.upload_file("report.pdf", display_name="Q3 Strategy")
# Query
model = genai.GenerativeModel('gemini-2.0-pro-exp', tools='fileSearch')
response = model.generate_content("Summarize sales from Q3?", tools=[store])
print(response.text) # Cited, accurate gold
Docs: File Search Guide. Drops fibs 80%—enterprise search in hours.
3. Structured Outputs: JSON Schemas That Stick
Enforce formats—no parsing hell.
// TS example with Zod-like schema
const schema = {
type: "object",
properties: {
name: { type: "string" },
age: { type: "number" },
hobbies: { type: "array", items: { type: "string" } }
}
};
const response = await model.generateContent(
"Extract from bio",
{ responseMimeType: "application/json", responseSchema: schema }
);
// Always valid—Pydantic/Zod ready!
Guide: Structured Outputs. Ideal for agents/DB feeds.
Stack 'Em: Travel Bot Dream
