For Agents
Look up real-time stock data and crypto quotes, and check API consumption from a focused four-endpoint financial data API.
Use for: I need to get the current price of a stock ticker, Look up a real-time crypto quote for a given symbol, Check how many API calls I have used this period, Verify the Aletheia API version my workflow is hitting
Not supported: Does not handle order placement, brokerage account access, or historical market data — use for real-time stock and crypto quote lookups only.
Jentic publishes the only available OpenAPI specification for Aletheia Financial API, keeping it validated and agent-ready. Aletheia provides real-time stock market and cryptocurrency data through a small, focused REST surface. The API exposes a stock data endpoint, a crypto quote endpoint, an account consumption endpoint for tracking quota usage, and a version probe. Authentication uses an API key passed in the 'key' header on every request.
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 | sh2
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 instanceJentic 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.
Retrieve real-time stock data for a given ticker symbol with /StockData
Fetch a current crypto quote for a symbol via /Crypto
Check current API consumption against the account quota with /v2/consumption
Probe the API version with /version for environment health checks
Embed market data into agent workflows without parsing ticker websites
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
The Aletheia API key is stored encrypted in the Jentic credential vault and injected as the 'key' header at execution time. The agent never has the raw key in its context.
Intent-based discovery
Agents search Jentic by intent (e.g. 'real-time stock quote', 'crypto price lookup'), and Jentic returns the matching Aletheia operation with its input schema for direct execution.
Time to first call
Direct Aletheia integration: a few hours, given the small surface. Through Jentic: under 15 minutes with search, load, and execute.

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 at https://app.jentic.com/sign-up.
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.
