# RentCast API

rentcast.io/main version 1.0. The API exposes 10 endpoints secured with apiKey authentication.

## For AI agents

Programmatically sale listings, property records. Covers 10 operations with apiKey authentication.

## Scope

Does not handle payments, communications, or crm - use for developer tools only.

## Capabilities

- Sale Listings
- Property Records
- Value Estimate
- Market Statistics
- Random Property Records
- Rent Estimate

## Use cases

### 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.

Example prompt: 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.

Example prompt: 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.

Example prompt: Search Jentic for 'sale listings', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring RentCast by hand means sending its API-key request header to api.rentcast.io and mapping its listings, properties, and valuation endpoints yourself. Through Jentic you install once, import RentCast from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** RentCast puts the property id in the URL path (`/properties/{id}`), so a rule can pin your agent to reading one property alongside its read-only listings and valuation lookups. You choose the operations it may call, so only the endpoints you allow will run.
- **Credential handling:** Your RentCast 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.
- **Discovery method:** Agents search Jentic by intent such as 'find sale listings' or 'estimate a property value', and Jentic returns the matching RentCast operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### 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 your Jentic One instance 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 through Jentic One, the self-hosted execution layer, 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.

### Can I limit what my agent is allowed to do with the RentCast API?

Yes. Jentic One runs self-hosted on your own infrastructure, so your rules decide which RentCast operations and credentials the agent may use. Because RentCast takes the property id in the URL path at GET `/properties/{id}`, you can pin the agent to reading a single property alongside its read-only listings and valuation lookups such as GET `/listings/sale` and GET `/avm/value.` Only the endpoints you allow will run, and your stored API key is injected at execution time rather than exposed to the agent.
