Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the RentCast 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 | shStep 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.

Patterns agents use RentCast API for, with concrete tasks.
★ Developer Tools Operations
Use the RentCast API to perform developer tools operations programmatically. The API provides 10 endpoints covering core functionality including sale listings, property records, value estimate.
Call GET /listings/sale to sale listings
Automated Avm Management
Automate avm operations by combining multiple RentCast API endpoints. Agents can property records and then value estimate in a single workflow.
Call GET /properties to property records, then verify the result
AI Agent Integration via Jentic
AI agents discover and call RentCast 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 'sale listings', load the operation schema, and execute with Jentic-managed credentials
10 endpoints — rentcast.

Three things that make agents converge on Jentic-routed access.
Credential isolation
RentCast API apiKey credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'sale listings') and Jentic returns the matching RentCast API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct RentCast API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

Specific to using RentCast API through Jentic.
What authentication does the RentCast API use?
The RentCast API uses an API key passed in the `X-Api-Key` header. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I sale listings with the RentCast API?
Yes. Use the GET /listings/sale endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the RentCast 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 sale listings through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'sale listings'. Jentic returns the matching RentCast API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the RentCast API have?
The RentCast API exposes 10 endpoints covering avm, listings, markets operations.
