Kurage Crypto Brainkcbrain — OSS trading intelligence, metered via x402
19 SKILLS · DEEPSEEK V4 FLASH · PAY PER CALL

Five open-source trading intelligences. One metered brain.

Kurage Crypto Brain vendors the LLM intelligence of five open-source crypto trading projects — ai-hedge-fund-crypto, CryptoTradingAgents, Vibe-Trading, LLM_trader, HELM Agents — pinned to exact commits with full attribution, and runs them on DeepSeek V4 Flash (local Gemma 4 12B is also selectable). You pay per call via x402 (USDC on Base, or JPYC on Polygon): no signup, no subscription — the 402 challenge is the onboarding. Judgment only: the API holds no exchange credentials and cannot place orders.

Kurage — jellyfish AI VTuber

Kurage 🪼

The same jellyfish AI VTuber behind kfreqai and kfxai. This is her crypto brain, for rent — the sibling of Kurage FX Brain.

⚠️ Analysis and judgment only — never investment advice, and never order execution. Outputs are LLM opinions grounded in the evidence you supply; the API honestly reports missing data instead of inventing it. Crypto trading involves substantial risk, including leverage risk.

The vendored anthology

Pinned commits, permissive licenses only, upstream attribution in every response. No license = not vendored (we checked).

MIT

ai-hedge-fund-crypto

The exact generate_trading_decision() portfolio-manager prompt, unpatched — synthesizes supplied analyst signals into a position proposal. Single call.

Apache-2.0

CryptoTradingAgents

Bull researcher → bear researcher → research-manager debate chain, on real evidence you supply. Three sequential LLM calls, priced accordingly at $0.003. Everything else is $0.001.

MIT

Vibe-Trading

The crypto_trading_desk.yaml preset: funding/basis, liquidation, and flow specialist roles chained into a desk-risk-manager synthesis. Multi-agent, priced at $0.003.

MIT

LLM_trader

Fresh-analysis, prompt-version, and decision-gating rules from the upstream prompt builder — trend, momentum, funding, confluence, risk/reward in one structured call.

Apache-2.0

HELM Agents

Four analyst prompts (market, sentiment, news, fundamentals) chained into a portfolio-manager consensus rating. Five sequential LLM calls, priced at $0.003.

ORIGINAL · CORE

Core judgment + market intelligence

Not vendored — kcbrain originals: single-call technical / on-chain / sentiment / full-perspective analysis, bull-bear debate mapping, trade / risk / portfolio / review judgments, plus multi-pair opportunity and flow ranking, anomaly detection, liquidation-cascade risk, and a single-pair evidence-bounded signal. Uses only the evidence you supply.

TRUST BOUNDARY

The brain can't touch money

No exchange credentials, no order sizes, no execution — ever. Visible errors instead of silent fallbacks. Your trading body (like the open-source kfreqai, or NOFX via the OpenAI-compatible /v1/chat/completions integration) keeps the final risk gates.

Try before you pay — two ways

We built verification in, because "trust me" is not a sales pitch.

1. The free browser Workbench

The Crypto Intelligence Workbench is a live console against the same API: pick an endpoint, load a BTC/USDT preset or paste your own evidence JSON, and read the structured judgment — with a health indicator showing the DeepSeek backend is actually up. Judge the quality yourself before spending a cent.

2. Verify the x402 machinery without paying

Every paid endpoint answers unpaid requests with a signed 402 challenge — so you can confirm the exact price, wallet, and network before any money moves:

curl -X POST https://bittensorman.xyz/kcbrain/decide/trade
# → HTTP 402: {"maxAmountRequired":"1000", "payTo":"0x444f…", "network":"base", …}

The full catalog is machine-readable at https://bittensorman.xyz/.well-known/x402.json — 24 paths under /kcbrain/. JPYC rail: https://exbridge.ddns.net:18331/kcbrain/… (0.15 JPYC per call, 0.45 JPYC for the chained multi-agent skills). Also on Bankr (single-call skills only, flat $0.001).
