Runnerflo B2B AI & FaaS SDK Reference

Integrate 17 AI models and general-purpose serverless functions into your SaaS applications with zero monthly deposits and automatic end-user payment validation.

1. The Zero-Friction B2B2C Architecture

Runnerflo provides a zero-friction model designed specifically for SaaS builders:

✓ $20 Lifetime Pass: Pay once via Geo-Routing Xendit, access forever. Includes 100 free test credits upon 1x24h account verification.
✓ No Monthly Deposits: You do NOT need to surrender credit cards or maintain prepaid monthly balances to serve production traffic.
✓ Polar.sh Merchant of Record (MoR): Handle global European VAT and US Sales Tax compliance out-of-the-box without requiring $1,000 US LLC setup fees.
✓ Custom Profit Margin: Configure your desired markup percentage (e.g. +200%). End-users are billed automatically, Runnerflo retains base GPU cost, and your profit is credited directly to your Payout Wallet.

2. Quickstart Code Examples
