Tiingo provides a financial data API for stock prices, crypto, IEX real-time data, and financial news. Data includes EOD prices, intraday data, and curated news from major financial sources. The API exposes 5 endpoints secured with bearer authentication.
Install Jentic One Beta
Connect the Tiingo API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Tiingo 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Ftiingo.com%2Ftiingo" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Ftiingo.com%2Ftiingo" | 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 Tiingo API.
Get daily stock prices
Manage finance data programmatically
Integrate Tiingo API into automated workflows
Query and filter Tiingo API records by parameters
Monitor Tiingo API operational status and events
Use Cases
Patterns agents use Tiingo API for, with concrete tasks.
★ Finance and Accounting Operations
Use the Tiingo API to perform finance operations programmatically. The API provides 5 endpoints covering core functionality including get daily stock prices, get ticker metadata, get crypto prices.
Call GET /tiingo/daily/{ticker}/prices to get daily stock prices
Automated Crypto Management
Automate crypto operations by combining multiple Tiingo API endpoints. Agents can get ticker metadata and then get crypto prices in a single workflow.
Call GET /tiingo/daily/{ticker} to get ticker metadata, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Tiingo API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle bearer tokens manually.
Search Jentic for 'get daily stock prices', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Tiingo API by hand means setting up its bearer token, targeting the api.tiingo.com host, and building the daily price, crypto, IEX, and news calls yourself. Through Jentic you install once, import the Tiingo API from the API Directory, store the token once, and your agent calls it.
Permission scoping
Tiingo puts the ticker in the URL path (/tiingo/daily/{ticker}/prices, /iex/{ticker}/prices), so a rule can pin your agent to one ticker: it can read prices and metadata for that symbol and nothing else. Every operation is read-only, so the agent stays limited to the lookups you grant.
Credential isolation
Your Tiingo token 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 daily stock prices for a ticker' or 'get crypto prices', and Jentic returns the matching Tiingo API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Tiingo API through Jentic.
What authentication does the Tiingo API use?
The Tiingo API uses a Bearer token in the Authorization header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I get daily stock prices with the Tiingo API?
Yes. Use the GET /tiingo/daily/{ticker}/prices endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Tiingo API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I get daily stock prices through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get daily stock prices'. Jentic returns the matching Tiingo API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Tiingo API have?
The Tiingo API exposes 5 endpoints covering crypto, iex, news operations.
Can I limit what my agent is allowed to do with the Tiingo API?
Yes. Because you run Jentic One yourself, your own rules decide which Tiingo operations and credentials the agent may use. Tiingo puts the ticker in the URL path, such as GET /tiingo/daily/{ticker}/prices and GET /iex/{ticker}/prices, so you can pin the agent to a single symbol and let it read only that ticker's prices and metadata. Every Tiingo operation is read-only, so the agent stays limited to the lookups you grant, including daily prices, crypto prices, and financial news.
