Install Jentic One Beta

Connect the Tatum Blockchain Data API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Tatum Blockchain Data 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%2Ftatum.io%2Ftatum" | sh

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%2Ftatum.io%2Ftatum" | 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.

Use Cases

Patterns agents use Tatum Blockchain Data API for, with concrete tasks.

★ Payments Operations

Use the Tatum Blockchain Data API to perform payments operations programmatically. The API provides 8 endpoints covering core functionality including get token data by contract address, get wallet balances at a specific blockchain moment, get wallet portfolio overview.

Call GET /tokens to get token data by contract address

Automated Collections Management

Automate collections operations by combining multiple Tatum Blockchain Data API endpoints. Agents can get wallet balances at a specific blockchain moment and then get wallet portfolio overview in a single workflow.

Call GET /wallet/balance/time to get wallet balances at a specific blockchain moment, then verify the result

AI Agent Integration via Jentic

AI agents discover and call Tatum Blockchain Data 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 apiKey tokens manually.

Search Jentic for 'get token data by contract address', load the operation schema, and execute with Jentic-managed credentials

Key Endpoints

8 endpoints — tatum blockchain data api providing access to token data, wallet balances, nft collections, transactions, and staking information across 20+ blockchain networks.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Tatum Blockchain Data API by hand means sending its x-api-key header on every request, targeting the api.tatum.io/v4/data host, and building your own retry handling across its data endpoints. Through Jentic you install once, import the Tatum Blockchain Data API from the API Directory, store the API key once, and your agent calls it.

Permission scoping

The Tatum Blockchain Data API's listed operations are read-only lookups where the target travels as query parameters, so limit the agent to the operations it needs, such as fetching token data or a wallet portfolio. You choose what it may call, and these endpoints only read data, so nothing that changes state is included.

Credential isolation

Your Tatum 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 token data by contract address' or 'check a wallet balance', and Jentic returns the matching Tatum Blockchain Data API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Tatum Blockchain Data API through Jentic.

What authentication does the Tatum Blockchain Data API use?

The Tatum Blockchain Data API uses an API key passed in the `x-api-key` 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 token data by contract address with the Tatum Blockchain Data API?

Yes. Use the GET /tokens endpoint. The API returns structured JSON responses that agents can parse and act on directly.

What are the rate limits for the Tatum Blockchain Data 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 token data by contract address through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get token data by contract address'. Jentic returns the matching Tatum Blockchain Data API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

How many endpoints does the Tatum Blockchain Data API have?

The Tatum Blockchain Data API exposes 8 endpoints covering collections, staking, tokens operations.

Can I limit what my agent is allowed to do with the Tatum Blockchain Data API?

Yes. Because Jentic One is self-hosted, you decide which Tatum Blockchain Data API operations your agent may call and which credentials it may use. Every listed endpoint is a read-only lookup, so you can restrict the agent to just the calls it needs, such as GET /tokens for token data or GET /wallet/portfolio for a wallet overview, while leaving out others like transaction history or staking. Since these endpoints only read data and never change state, the agent cannot alter anything with this API.
