by RateAPI

Overview

Get real-time financing rates from 4,200 credit unions across all 50 states—covering mortgages, auto loans, HELOCs, personal loans, and credit cards. RateAPI delivers personalized recommendations based on your location, loan amount, and credit profile, with interactive comparisons and rate monitoring. Unlike estimate-based calculators, every rate comes from actual credit union data, helping you find competitive offers that traditional rate sites often miss.

Tools

create_monitor

ChatGPT

Create a new decision monitor that watches for rate changes and sends webhook notifications when conditions are met. Returns the monitor with a webhook_signing_secret for verifying webhook payloads.

delete_monitor

ChatGPT

Permanently delete a monitor. This action cannot be undone.

deliver_test_webhook

ChatGPT

Send a test webhook for a monitor using a simulated rate change. This actually delivers an HTTP request to the monitor's configured webhook URL. Only use when the user explicitly requests a test webhook delivery.

get_benchmarks

ChatGPT

Get rate benchmark statistics (min/median/max APR) across all institutions. Use this for market analysis, comparing user quotes against market rates, or building benchmark dashboards. Returns statistics for mortgages (30yr/15yr), auto loans (new/used), HELOCs, and personal loans. Each product shows the lowest APR institution, median APR, and count of institutions.

get_credit_union

ChatGPT

Reference tool: Get detailed info and all mortgage rates for a specific credit union by state and slug. Use this when a user asks about a specific credit union. For personalized rate recommendations, use get_financing_decision instead.

get_extraction_stats

ChatGPT

Get data extraction statistics showing the scale and health of rate data collection. Use this to understand extraction volumes, product coverage, and data freshness. Supports filtering by date range and product type. Great for building transparency dashboards or monitoring data collection health.

list_monitors

ChatGPT
