For Agents

Pull cryptocurrency prices, volumes, market caps, and OHLCV candle data across thousands of coins and exchanges from Nomics on behalf of trading and analytics tools.

Install Jentic One Beta

Connect the Nomics Cryptocurrency API to your agent

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

Capabilities

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Nomics Cryptocurrency API, keeping it validated and agent-ready. Nomics provides cryptocurrency market data covering thousands of coins and exchanges, with current and historical prices, volumes, market caps, OHLCV candles, and exchange-rate conversions. The API is built around currency tickers, exchange tickers, market data, supply intervals, and aggregated candles, with sparkline series for chart rendering. Trading platforms, portfolio dashboards, and data analysts use it as a price feed and historical reference for crypto assets.

Use Cases

Patterns agents use Nomics Cryptocurrency API for, with concrete tasks.

★ Crypto portfolio valuation

Portfolio dashboards displaying live crypto holdings need current prices for each held asset, denominated in the user's fiat currency. The Nomics /currencies/ticker endpoint returns price, 1h, 1d, 7d, and 30d change for a list of currency IDs in a single call, and /exchange-rates converts between fiats. An agent can refresh a portfolio's USD value with two requests rather than per-coin lookups.

Call /currencies/ticker with ids=BTC,ETH,SOL,LINK and convert=USD, then sum holdings * price for the user's portfolio

Backtesting trading strategies

Quants backtesting strategies need clean OHLCV candles at a specific interval over a long history. Nomics /candles returns aggregated candles synthesised across exchanges, removing the need to merge per-exchange data manually. An agent can pull years of 1h or 1d candles for any supported pair and feed them straight into a backtest.

Call /candles with currency=BTC, interval=1d, and start of 2024-01-01 to retrieve daily candles for backtest input

Market sentiment dashboard

Analyst dashboards combining global market metrics with per-exchange flows can pull /market-cap/history and /volume/history for the macro view, then drill into /exchanges/volume/history for individual venues. This produces the 'where is the volume going' view that crypto reporters and fund managers use to spot rotations between exchanges.

Pull /market-cap/history and /volume/history for the past 90 days and chart total market cap against total volume

AI agent for crypto price queries

An AI assistant answering 'what's the price of ETH right now' can use Jentic to find the matching Nomics operation, call /currencies/ticker for ETH, and return the current price plus 24h change. Through Jentic the agent never holds the API key and the operation is discoverable by intent rather than by reading Nomics documentation.

Through Jentic, search 'get current cryptocurrency price', load /currencies/ticker, and execute with ids=ETH and convert=USD

Why Jentic?

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

Credential isolation

Nomics API keys are stored encrypted in the Jentic vault and appended as the 'key' query parameter by the runtime. Agents never hold the raw key.

Intent-based discovery

Agents search Jentic by intent (e.g. 'get current crypto price') and Jentic returns the matching Nomics operation with its input schema, so the agent calls /currencies/ticker without browsing docs.

Time to first call

Direct Nomics integration: 1 day for query string auth, response parsing, and rate-limit handling. Through Jentic: under 30 minutes — search, load schema, execute.

FAQs

Specific to using Nomics Cryptocurrency API through Jentic.

Why is there no official OpenAPI spec for Nomics Cryptocurrency API?

Nomics does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Nomics Cryptocurrency API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Nomics API use?

Nomics uses an API key passed as the 'key' query parameter on every request. Through Jentic, the key is stored in the encrypted vault and appended to the request URL by the runtime — agents never see the raw key in their context.

Can I get OHLCV candles for any cryptocurrency from Nomics?

Yes. /candles returns aggregated OHLCV bars for a given currency and interval. Supported intervals are typically 1d and longer; for sub-daily data, check the parameter documentation on the spec since not all coins have full history.

What are the rate limits for the Nomics API?

Nomics rate limits depend on your subscription tier and are not encoded in the OpenAPI spec. Free keys typically allow about 1 request per second; paid plans raise that ceiling. Cache ticker data for 30-60 seconds and historical /candles results indefinitely to stay well under the limit.

How do I get the current Bitcoin price through Jentic?

Install with pip install jentic, then search 'get current cryptocurrency price', load /currencies/ticker, and execute with ids=BTC and convert=USD. The response includes current price, percent changes over standard windows, and 24h volume.

Does the Nomics API support trading or order placement?

No. Nomics is a market data provider only — it does not place trades, hold balances, or execute orders. Pair it with an exchange API such as Kraken or Binance when you need to act on the data.
