# KosherNinja AKX

> Agent-first behavioral scoring data derived from authentic Jewish ethical literature. Download data, score locally. Zero API calls after purchase.

## Overview

KosherNinja provides behavioral scoring datasets for AI agents. 14,000+ ethical rules extracted from Torah, Talmud, Mishnah, and other authentic Jewish literature. Each rule has source provenance tracing back to physical texts.

Agents download scoring data once ($50 USDC via x402 protocol on Base network), then compute behavioral scores locally using cosine similarity against 1536-dim embeddings. No ongoing API calls, no latency, no server cost.

## Payment

x402 protocol on Base network (chain ID 8453). USDC payments to wallet `0x877875efB62A7C20066bbE36a0535c829408Cb58`. Coinbase AgentKit agents handle 402 responses automatically via `retry_http_request_with_x402`.

## How Scoring Works

1. Download scoring-index.json (1000 rules + embeddings)
2. Embed your agent's action text using text-embedding-3-small (1536 dimensions)
3. Compute cosine similarity against all rule embeddings
4. Take top-10 matching rules per category
5. Apply weighted scoring formula per category
6. Get overall behavioral score (0-100)
