ContentForge — Content Intelligence API

45 endpoints · 12 platforms · Deterministic scoring in <50ms · No AI hallucinations

Score content before you post. ContentForge is a Content Intelligence API — a before-publish quality gate that grades every tweet, LinkedIn post, headline, and ad copy with a deterministic A–F score, actionable suggestions, and a PASSED | REVIEW | FAILED verdict in under 50ms — no LLM involved in the scoring layer.

Think of it as a digital ruler for content quality. A ruler doesn't need a dataset to tell you something is 12 inches long — it just needs to be correctly calibrated. ContentForge's heuristic engine is that ruler: zero variance on the same input, zero hallucinations, fully auditable open-source logic. AI (Ollama or Gemini) kicks in only for generation endpoints like rewrites, hooks, and subject lines.

import requests

HEADERS = {"X-RapidAPI-Key": "YOUR_KEY", "X-RapidAPI-Host": "contentforge1.p.rapidapi.com"}

r = requests.post("https://contentforge1.p.rapidapi.com/v1/score_tweet",
    headers=HEADERS,
    json={"text": "I'm working on a new project."})
# → {"score": 32, "grade": "C", "quality_gate": "FAILED", "suggestions": [...]}

r = requests.post("https://contentforge1.p.rapidapi.com/v1/score_tweet",
    headers=HEADERS,
    json={"text": "Got 100 signups in 24 hours 🚀 Here's the copy that converted: #buildinpublic"})
# → {"score": 91, "grade": "A", "quality_gate": "PASSED", "suggestions": []}

Why Deterministic Scoring?

Every LLM-based scorer has the same flaw: ask it to score the same tweet twice and you'll get two different answers. For a professional content workflow, that's not a tool — that's a vibe check.

ContentForge's scoring layer is pure Python heuristics. Same input → same output, every time. The logic is open source; you can read exactly why a post scored 74 and not 83. This is the Deterministic Advantage:

	ContentForge	LLM-based scoring
Response time	<50ms	1–5 seconds
Variance on same input	0%	~15–30%
Explainability	Full — every deduction itemised	Black box
Cost per call	Free (heuristics)	$0.001–0.01 per call
Self-hostable	✅ (python scripts/api_prototype.py)	Depends on provider

Self-Hosting

ContentForge runs fully locally with Ollama. No external AI calls needed for scoring.

git clone https://github.com/CaptainFredric/ContentForge.git
cd ContentForge
pip install -r requirements.txt
python scripts/api_prototype.py
# → Listening on http://localhost:5000

What runs locally with zero external calls:

• All 12 platform scorers (deterministic, <50ms)
• Quality gate evaluation (PASSED / REVIEW / FAILED)
• Rate limiting and proof dashboard

What uses Ollama locally or falls back to Gemini:

• Hook generation, rewrites, bio generation, subject lines, ad copy

LLM chain: Ollama first → Gemini 2.5 Flash if Ollama unavailable → model rotation. If Ollama is running locally, nothing leaves your machine for AI calls.
