Install Jentic One Beta

Connect the Homebuyer.com Mortgage Rates API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Homebuyer.com Mortgage Rates 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%2Fhomebuyer.com%2Fhomebuyer" | 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%2Fhomebuyer.com%2Fhomebuyer" | 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 Homebuyer.com Mortgage Rates API for, with concrete tasks.

★ Refinance Decision Assistant

Power a refinance assistant that pulls live mortgage rates from Homebuyer.com and compares them against a borrower's existing loan terms. The agent calls GET /rates to retrieve the current conforming, jumbo, FHA, and VA rates, then computes monthly payment savings and break-even points. Integration is fast because there is only one endpoint to wire up and authentication is a single API key in a header.

Call GET /rates and return the current 30-year conforming fixed rate alongside the prior day's rate so the user can see the day-over-day delta.

Homebuyer Affordability Coach

Embed live mortgage rates into a homebuyer affordability coach so the user sees realistic monthly payments based on today's market. The assistant pulls Homebuyer.com rates, applies them to the user's target home price and down payment, and explains how rate changes shift purchasing power. Useful for first-time buyer chatbots and lender lead-capture forms.

Retrieve the current FHA 30-year rate via GET /rates and compute the monthly principal-and-interest payment for a $350,000 home with 3.5% down.

Daily Rate Briefing for Real Estate Teams

Generate a daily mortgage rate briefing for real estate brokers and loan officers. An agent calls GET /rates each morning, formats the conforming, jumbo, FHA, VA, and USDA snapshots into a short summary, and posts it to Slack or email. Replaces manual rate-sheet copy-paste workflows.

Pull today's rates from GET /rates, format a multi-product summary, and post the briefing to a Slack channel at 8am each weekday.

AI Agent Mortgage Lookup via Jentic

Expose Homebuyer.com mortgage rates to a conversational AI agent through Jentic so the agent can answer rate questions without scraping or maintaining custom HTTP clients. Jentic handles credential storage, schema discovery, and execution. The agent searches for 'current mortgage rates', loads the GET /rates schema, and executes the call in one flow.

Use Jentic to search 'current mortgage rates', load the homebuyer_get_rates schema, and execute a call returning all five loan products in a structured response.

Why Jentic?

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

Setup

Wiring Homebuyer.com by hand means setting up its X-API-Key header auth and picking the right host between api.homebuyer.com and homebuyer.com/api/v1 yourself. Through Jentic you install once, import the Homebuyer.com Mortgage Rates API from the API Directory, store the key once, and your agent calls it.

Permission scoping

This API exposes one read-only rates lookup, so scope your agent to the operation it needs: reading the current mortgage rate snapshot. You choose the operations it may call, so nothing beyond that read is included in the allowed set.

Credential isolation

Your Homebuyer.com 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 'current US mortgage rates', and Jentic returns the GET /rates operation with its input and output schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Homebuyer.com Mortgage Rates API through Jentic.

Why is there no official OpenAPI spec for Homebuyer.com Mortgage Rates API?

Homebuyer.com does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Homebuyer.com Mortgage Rates API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Homebuyer.com Mortgage Rates API use?

The API uses an API key passed in a request header. Jentic stores the key encrypted in your Jentic One instance and injects it at execution time, so the raw key never enters the agent's context window.

Can I get FHA and VA rates with the Homebuyer.com Mortgage Rates API?

Yes. The single GET /rates endpoint returns rate snapshots for conforming, jumbo, FHA, VA, and USDA loan products in one response, so an agent can pick the product it needs without additional calls.

What are the rate limits for the Homebuyer.com Mortgage Rates API?

The API is in public beta and rate limits may change. Treat it as low-volume polling friendly (a few calls per minute is safe) and cache the response when serving multiple users from the same snapshot.

How do I fetch current mortgage rates with the Homebuyer.com API through Jentic?

Install the SDK with pip install jentic, then search for 'current mortgage rates', load the GET /rates schema, and execute the call. Jentic handles auth and returns the structured rate snapshot directly to your agent.

Is the Homebuyer.com Mortgage Rates API free?

The API is currently in public beta. Pricing and access tiers are not yet finalised, so check Homebuyer.com directly for the latest commercial terms before going to production.

Can I limit what my agent is allowed to do with the Homebuyer.com Mortgage Rates API?

Yes. Because you run Jentic One yourself, you decide which operations and credentials your agent may use, and your own rules define the allowed set. This API exposes just one read-only operation, the GET /rates lookup that returns current conforming, jumbo, FHA, VA, and USDA rate snapshots, so you can scope the agent to that single read and nothing else. Your API key stays encrypted in your own instance and is injected only when that permitted call runs.
