Install Jentic One Beta

Connect the Poloniex API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Poloniex API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Poloniex is a cryptocurrency exchange offering spot trading for hundreds of digital assets including Bitcoin, Ethereum, and altcoins. The Poloniex API provides programmatic access to market data, order placement, account management, and wallet operations. Traders use it to implement automated trading strategies, arbitrage bots, and portfolio rebalancing algorithms. The API supports both REST endpoints for account queries and order management, plus WebSocket streams for real-time price feeds and order book updates. Institutions and quantitative trading firms integrate Poloniex to execute high-frequency strategies, manage cross-exchange positions, and aggregate liquidity. The API includes advanced order types like stop-limit and fill-or-kill, margin trading capabilities, and lending market access for earning yield on idle crypto holdings.

Use Cases

Patterns agents use Poloniex API for, with concrete tasks.

★ Automated Trading Strategy Execution

Quantitative traders and crypto funds use the API to implement algorithmic trading strategies like momentum trading, mean reversion, and statistical arbitrage. Trading bots query real-time price feeds, calculate technical indicators like RSI and MACD, and execute buy/sell orders based on signal generation. The API's order management endpoints enable strategies to track fill rates, manage position sizes, and implement stop-loss protection. Traders backtest strategies using historical data endpoints, then deploy live bots that run 24/7 to capitalize on crypto market volatility.

Query Poloniex for BTC/USDT current price and order book depth, calculate trading signal using RSI indicator, place limit buy order if signal triggers, monitor order status, adjust position sizing based on account balance.

Cross-Exchange Arbitrage and Liquidity Aggregation

Crypto arbitrage firms monitor price differences across Poloniex and other exchanges like Binance, Coinbase, and Kraken. The API enables real-time price queries for the same trading pair on multiple venues, identifying arbitrage opportunities when spreads exceed trading fees. Bots execute simultaneous buy/sell orders across exchanges to capture risk-free profit. The account activity endpoints enable reconciling positions and calculating net P&L across venues. This increases market efficiency while generating consistent returns for arbitrage operators.

Fetch BTC/USDT price from Poloniex and competitor exchanges, calculate spread after fees, if spread exceeds threshold execute buy on cheaper exchange and sell on expensive exchange, transfer funds via wallet operations to rebalance.

Portfolio Management and Rebalancing

Crypto portfolio managers and robo-advisors use the API to implement automated rebalancing strategies that maintain target asset allocations. The API's account balance endpoints provide real-time portfolio valuations, while market data endpoints supply current prices for rebalancing calculations. When an asset drifts beyond tolerance bands (e.g., Bitcoin allocation drops from 40% to 35%), the bot sells overweight positions and buys underweight assets. This maintains risk-adjusted returns and prevents concentration risk, operating continuously across multiple client accounts.

Query account balances for all assets, calculate current portfolio weights using market prices, compare to target allocation, generate rebalancing trades to restore weights, execute orders, log rebalancing activity for reporting.

Market Making and Liquidity Provision

Professional market makers use the API to provide liquidity on Poloniex trading pairs, earning spreads between bid and ask prices. Market making bots place limit orders on both sides of the order book, continuously adjusting prices based on mid-market movements and inventory risk. The API's order book endpoints enable calculating optimal quote prices, while order management endpoints allow rapid cancellation and replacement as market conditions change. Market makers earn rebates from exchanges for providing liquidity while managing inventory risk through hedging strategies.

Query order book for target trading pair, calculate mid-market price and spread, place limit buy order below mid and limit sell above mid, monitor inventory levels, cancel and replace orders as market moves, hedge inventory on other exchanges.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Poloniex API keys and secrets are encrypted in Jentic's vault with permission scope (read, trade, withdraw). Agents execute operations without accessing raw credentials, and Jentic handles HMAC-SHA256 signature generation for each request.

Intent-based discovery

Agents search by intent like 'place a limit order for Bitcoin' and Jentic returns Poloniex order placement operations with parameter schemas for order type, side, price, and quantity, avoiding documentation of signature algorithms.

Time to first call

Direct Poloniex integration: 3-5 days to implement authentication, order management, error handling, and WebSocket connections. Through Jentic: 1-2 hours—search for operations, execute trades with natural language parameters, handle responses.

FAQs

What authentication does the Poloniex API use?

The Poloniex API uses API key authentication with HMAC-SHA256 signatures. You generate API keys in your Poloniex account settings with specific permissions (read-only, trading, withdrawals), then sign each request with your secret key.

Does Poloniex support WebSocket for real-time data?

Yes, Poloniex provides WebSocket endpoints for streaming real-time price updates, order book changes, and account activity. Use REST endpoints for historical data and account management, and WebSockets for live market data in trading bots.

What order types does the Poloniex API support?

The API supports market orders, limit orders, stop-limit orders, fill-or-kill, immediate-or-cancel, and post-only orders. This enables sophisticated trading strategies including stop-loss protection and maker-only liquidity provision.

Can I transfer crypto between different wallet types on Poloniex?

Yes, the accounts/transfer endpoint enables moving funds between spot, margin, and lending wallets within your Poloniex account. This is useful for allocating capital to different trading strategies or earning yield on idle balances.

How do AI agents use the Poloniex API through Jentic?

Agents search Jentic for tasks like 'get Bitcoin price on Poloniex' or 'place a limit order' and receive operation schemas. Jentic vaults API keys, handles HMAC signature generation, and allows agents to execute trades, query balances, and analyze market data with natural language instructions.
