For Agents
Programmatically create list, get lists. Covers 25 operations with apiKey, bearer, oauth2 authentication.
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the TheirStack API Reference, 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%2Ftheirstack.com%2Ftheirstack" | shStep 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%2Ftheirstack.com%2Ftheirstack" | 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.

Introduction Welcome to TheirStack’s API! <br> You can use this API to access all our API endpoints, such as the [Jobs endpoint](https://api.theirstack.com) to get real-time and historical jobs from more than 100 countries or the [Companies endpoint](https://api.theirstack.com) to get a list of companies by the technology they use or by the roles they are hiring for. The API is organized around [R. The API exposes 25 endpoints secured with apiKey, bearer, oauth2 authentication.
Add Companies To List
Patterns agents use TheirStack API Reference API for, with concrete tasks.
★ Identity and Authentication Operations
Use the TheirStack API Reference to perform identity auth operations programmatically. The API provides 25 endpoints covering core functionality including create list, get lists, get list.
Call POST /v0/company_lists to create list
Automated Company Lists Management
Automate company lists operations by combining multiple TheirStack API Reference endpoints. Agents can get lists and then get list in a single workflow.
Call GET /v0/company_lists to get lists, then verify the result
AI Agent Integration via Jentic
AI agents discover and call TheirStack API Reference 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, bearer, oauth2 tokens manually.
Search Jentic for 'create list', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring TheirStack by hand means picking among its token, bearer, and OAuth2 schemes against api.theirstack.com and handling the company-list endpoints yourself. Through Jentic you install once, import TheirStack from the API Directory, store the credential once, and your agent calls it.
Permission scoping
TheirStack puts the list id in the URL path (/v0/company_lists/{list_id}), so a rule can pin your agent to one company list. You choose the operations it may call, so destructive ones like deleting a list or removing companies are not included unless you add them.
Credential isolation
Your TheirStack credential 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 'create a company list' or 'add companies to a list', and Jentic returns the matching TheirStack operation with its input schema so the agent calls the right endpoint without browsing the reference docs.
Alternatives and complements available in the Jentic catalogue.
Specific to using TheirStack API Reference API through Jentic.
What authentication does the TheirStack API Reference use?
The TheirStack API Reference uses apiKey, bearer, oauth2 authentication. 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 create list with the TheirStack API Reference?
Yes. Use the POST /v0/company_lists endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the TheirStack API Reference?
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 create list through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create list'. Jentic returns the matching TheirStack API Reference operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the TheirStack API Reference have?
The TheirStack API Reference exposes 25 endpoints covering company lists, saved searches, catalog operations.
/v0/company_lists/{list_id}/companies
Get List Companies
/v0/company_lists/{list_id}/add_companies
Add Companies To List
