For Agents

Look up real-time stock data and crypto quotes, and check API consumption from a focused four-endpoint financial data API.

Install Jentic One Beta

Connect the Aletheia Financial API to your agent

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

What an agent can do with Aletheia Financial API.

Use Cases

Patterns agents use Aletheia Financial API for, with concrete tasks.

★ Real-time stock watchlist for an internal tool

An ops team builds an internal page that shows live prices for a list of tracked tickers by calling /StockData for each symbol on a short refresh interval. The minimal surface area means the integration is low-effort: a single GET with the ticker as a parameter and an API key header is enough to render a watchlist.

GET /StockData for each ticker in the watchlist and render the resulting price and change values in the dashboard

Crypto quote lookup before a trade alert

A trading assistant agent receives a 'check BTC price' message and calls GET /Crypto with the BTC symbol to fetch the latest quote, then formats and posts the result to the user. Because the endpoint is read-only, the agent never needs trading credentials - only a market data API key.

GET /Crypto with symbol=BTC and post the formatted price and 24h change back to the user channel

API quota awareness for batch jobs

A back-office batch job runs through hundreds of tickers nightly. Before the run, it calls GET /v2/consumption to confirm there is enough quota left in the period; if not, it pages an operator instead of silently failing partway through. This keeps batch reliability high without a separate quota tracker.

GET /v2/consumption before starting the batch and abort if remaining quota is below the projected request count

Agent-driven price lookup through Jentic

A Jentic agent answers questions like 'what's the price of NVDA right now?' by calling /StockData with the ticker and returning the latest price. Because Aletheia is small and focused, the agent does not have to choose between dozens of operations - Jentic surfaces the single matching endpoint.

Search Jentic for 'real-time stock price for a ticker', execute GET /StockData with the requested symbol, and return the price field

Why Jentic?

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

Credential isolation

Your Aletheia API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'get a real-time stock quote' or 'look up a crypto price', and Jentic returns the matching Aletheia operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Aletheia Financial API through Jentic.

Why is there no official OpenAPI spec for Aletheia Financial API?

Aletheia does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Aletheia Financial API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Aletheia Financial API use?

Aletheia uses an API key passed in the 'key' header on every request. Jentic stores the key encrypted in its credential vault and injects it as the header at execution time, so the raw key never enters the agent's prompt context.

Can I get a real-time stock price with the Aletheia API?

Yes. Call GET /StockData with the ticker symbol as a query parameter and the 'key' header. The endpoint returns the latest price along with related stock data fields.

What are the rate limits for the Aletheia Financial API?

The OpenAPI spec does not declare per-endpoint rate limits. Aletheia enforces a quota per billing period; call GET /v2/consumption to check remaining quota before kicking off batch lookups.

How do I look up a crypto quote through Jentic?

Search Jentic for 'aletheia crypto quote', load the schema for GET /Crypto, and execute it with the symbol you want. Jentic returns the quote payload directly to the agent without exposing the API key.

Does Aletheia provide historical price data?

The endpoints exposed in this spec are real-time only - /StockData and /Crypto return current values. For historical price series, pair Aletheia with a complementary historical market-data provider.

Can I limit what my agent is allowed to do with the Aletheia Financial API?

Yes. Jentic One runs self-hosted on your own infrastructure, so your rules decide which Aletheia operations and credentials the agent can use. Because the Aletheia Financial API is read-only quote lookup and passes its target as a query parameter rather than a path resource, you can restrict the agent to just the calls it needs, such as GET /StockData for stock prices or GET /Crypto for crypto quotes. You choose the operations it may call, so the /v2/consumption and /version reads stay off limits unless you add them.
