For Agents

Place and cancel cryptocurrency orders, read live order books, and pull account balances and trade history on Gemini.

Connect the Gemini REST API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Gemini REST 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.

Install Jentic One Beta (Self-Hosted)

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

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.

Capabilities

What an agent can do with Gemini REST API API.

Read real-time order book depth for any trading symbol via /v1/book/{symbol}

Place buy and sell orders, including limit, market, and stop variants, through /v1/order/new

Cancel a specific order with /v1/order/cancel or every open order at once with /v1/order/cancel/all

Pull account balances in native units and notional USD via /v1/balances and /v1/notionalbalances/{currency}

View OpenAPI Document

The Gemini REST API is the trading and account interface for Gemini, the regulated cryptocurrency exchange. It exposes 28 endpoints for public market data (order books, ticker, price feeds, trading symbols), authenticated trading (place new order, cancel single, cancel all, status), account state (balances, notional balances, transfers, deposit address creation), and historical activity (my trades, order history, fee promotions). Authentication uses HMAC-SHA384 with three headers — X-GEMINI-APIKEY, X-GEMINI-PAYLOAD, and X-GEMINI-SIGNATURE — over a base64-encoded JSON request payload.

Use Cases

Patterns agents use Gemini REST API API for, with concrete tasks.

★ Algorithmic Trading Bot

Run a strategy that places, cancels, and manages orders on Gemini. The agent watches /v1/book/{symbol} for liquidity, posts orders to /v1/order/new, and reconciles fills via /v1/order/status. Replaces a UI trader for high-frequency or systematic strategies.

Watch /v1/book/BTCUSD for the best bid, POST /v1/order/new with type=exchange limit, side=buy, and the calculated price; on fill, refresh balances via /v1/balances

Portfolio Reporting Across Crypto Holdings

Pull account-wide balances and notional USD values into a portfolio dashboard. The agent calls /v1/balances and /v1/notionalbalances/USD on a schedule and posts the aggregate to a finance dashboard. Eliminates manual exchange-by-exchange exports.

GET /v1/balances and /v1/notionalbalances/USD on an hourly cron, store the snapshot, and surface the totals on a portfolio page

Tax And Audit Trade History Export

Export complete trade history for tax season or an audit. The agent walks /v1/mytrades and /v1/orders/history paginated by timestamp, normalises the records, and writes them to a spreadsheet or accounting tool. Spares the team from manual CSV downloads.

POST /v1/mytrades with a symbol and timestamp range, paginate until empty, and write each fill to the destination ledger

Agent-Led Crypto Operations Through Jentic

AI agents discover Gemini through Jentic's intent search and execute trading or balance reads without implementing the HMAC-SHA384 signing flow themselves. Jentic isolates the API key and secret in its vault and produces the X-GEMINI-SIGNATURE header at execution time. Critical for an API where credential leakage is financially material.

Use Jentic search query 'place a crypto order on Gemini' to load the gemini_place_order tool and execute with symbol, side, type, and amount

Why though Jentic?

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

Credential isolation

Gemini API key and secret are stored encrypted in the Jentic vault. Jentic computes the X-GEMINI-SIGNATURE HMAC at execution time from the vaulted secret, so the agent never handles the signing key — material for an API that can move funds.

Intent-based discovery

Agents search by intent (e.g. 'place a crypto order on Gemini') and Jentic returns the matching operation among the 28 endpoints with its input schema, distinguishing /v1/order/new from /v1/order/status without manual disambiguation.

Time to first call

Direct Gemini integration: 1-2 days to wire HMAC-SHA384 signing, base64 payload encoding, and nonce handling. Through Jentic: under 30 minutes — search, load schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Kraken API

Kraken offers a comparable cryptocurrency trading API; Gemini is US-regulated and emphasises compliance-first trading.

Choose Kraken for broader coin coverage and margin features; choose Gemini when the user prioritises a US-regulated venue.

Alternative

Binance API

Binance has the deepest liquidity and broadest pair coverage; Gemini is smaller but US-regulated and integrates with traditional finance flows.

Choose Binance for global liquidity and feature breadth; choose Gemini for US users who require a regulated counterparty.

Alternative

Bitstamp API

Bitstamp is a long-running European exchange with similar order and account endpoints; Gemini is US-based and uses HMAC-SHA384 over base64 payloads.

Choose Bitstamp for European fiat rails and EUR pairs; choose Gemini for USD-denominated trading from the US.

FAQs

Specific to using Gemini REST API API through Jentic.

What authentication does the Gemini REST API use?

Gemini uses HMAC-SHA384 signing. Each authenticated request needs three headers — X-GEMINI-APIKEY, X-GEMINI-PAYLOAD (base64-encoded JSON request body), and X-GEMINI-SIGNATURE. Through Jentic the key and secret are stored encrypted in the vault and the signature is computed at execution time.

Can I place a limit order with the Gemini API?

Yes. POST /v1/order/new with type=exchange limit and the symbol, side, amount, and price fields. The response includes the assigned order_id which you can later pass to /v1/order/status or /v1/order/cancel.

How do I cancel all open orders at once?

Call POST /v1/order/cancel/all. Gemini cancels every open order under the API key's scope and returns a result list. Use /v1/order/cancel for cancelling a single order id instead.

What are the rate limits for the Gemini REST API?

Gemini's documented limits are 600 public requests per minute and 600 private requests per minute, with stricter caps on order placement bursts. Back off on HTTP 429 and consult docs.gemini.com for the current ceilings before scaling.

Can I generate a deposit address through the API?

Yes. POST /v1/deposit/{currency}/newAddress generates a new deposit address for that currency and returns the address string. Suitable for systems that rotate addresses per deposit for audit reasons.

How do I trade on Gemini through Jentic?

Install with pip install jentic, search 'place a crypto order on Gemini', load the gemini_place_order operation schema, and execute with symbol, side, type, amount, and price. Jentic computes the X-GEMINI-SIGNATURE header from the vaulted secret.
