How to Validate a SaaS Idea in 30 Minutes

An r/SideProject post described validation taking 3 hours per idea. Compress to 30 minutes with Scavio + an LLM.

An r/SideProject post described 3 hours per idea spent validating concepts. This tutorial compresses validation to 30 minutes with one Scavio call set and one LLM pass.

Prerequisites

  • Python or any HTTP client
  • Scavio API key
  • An LLM API key

Walkthrough

Step 1: State the idea in one sentence

Force precision.

Python
IDEA = 'AI tool that turns Reddit threads into competitor research briefs'

Step 2: Pull SERP for the idea

What already exists?

Python
import os, requests
H = {'x-api-key': os.environ['SCAVIO_API_KEY']}
serp = requests.post('https://api.scavio.dev/api/v1/search', headers=H, json={'query': f'{IDEA} 2026'}).json()

Step 3: Pull Reddit demand signal

Are people asking for this?

Python
reddit = requests.post('https://api.scavio.dev/api/v1/reddit/search', headers=H, json={'query': IDEA}).json()

Step 4: Pull YouTube discussion

Existing creator coverage indicates audience.

Python
yt = requests.post('https://api.scavio.dev/api/v1/youtube/search', headers=H, json={'query': IDEA}).json()

Step 5: Pass bundle to LLM with strict prompt

Single prompt returns verdict.

Text
# Prompt:
# 'Based on these 3 sources, return a JSON: {already_exists: bool, demand_signal: low|medium|high, top_3_competitors, biggest_objection, gut_call: yes|no|maybe}.'

Python Example

Python
# Total time: 30s of Scavio calls + 30s of LLM call + 5-10 min of reading.
# Total cost: ~$0.05 of Scavio + $0.10 of LLM tokens.

JavaScript Example

JavaScript
// Same in TS.

Expected Output

JSON
JSON verdict in 30 minutes. The founder triages 4-6 ideas in a workday instead of 1-2.
