Tier System

Fincept API uses a 4-tier system to organize modules by complexity and computational cost. This guide explains tier access, credit costs, and how to choose the right tier.

Overview

Tier	Cost	Modules	Endpoints	Access
Free	0 credits	2	65	Everyone
Basic	1 credit	4	130	Free + paid users
Standard	2 credits	6	178	Free + paid users
Pro	5 credits	6	124	Free + paid users

How Tiers Work

Access Model

All users can access all tiers - you just pay per use:

Free tier: Always 0 credits (unlimited access)
Basic/Standard/Pro: Credits deducted per request

You don’t need a subscription to access higher tiers! Free account users can call Pro tier endpoints - they just pay 5 credits per request.

Example: Free Account User

Account: Free (350 signup credits)
Can access:
   Free tier: Unlimited (0 credits)
   Basic tier: 350 requests (1 credit each)
   Standard tier: 175 requests (2 credits each)
   Pro tier: 70 requests (5 credits each)

Tier Breakdown

Free Tier (0 credits)

Volatility surfaces

Example cost: 100 requests = 200 credits = covered by Basic plan (500 credits/month)

Pro Tier (5 credits)

Modules: Models, Portfolio, Risk, Regulatory, ML, Physics Best for: Advanced models, risk management, regulatory compliance Key endpoints:

Heston model pricing
Portfolio optimization
VaR/CVA calculation
Basel III compliance
Credit scoring ML

Example cost: 100 requests = 500 credits = covered by Basic plan

Tier Access Control

Attempting Higher Tier Without Access

This is ALLOWED! You just pay the credit cost:

# Free account user calling Pro tier
curl -X POST https://api.fincept.in/quantlib/risk/var \
  -H "X-API-Key: fk_user_your_key" \
  -d '{"returns": [...], "confidence_level": 0.95}'

Response if sufficient credits:

{
  "success": true,
  "data": {"var": 0.0234}
}

Credits deducted: 5 Response if insufficient credits:

{
  "success": false,
  "message": "Insufficient credits",
  "detail": "Required: 5 credits, Available: 2 credits"
}

{
  "account_type": "enterprise",
  "credit_balance": "unlimited",
  "tier_access": "all"
}
