}About the nerdwallet.com API
The NerdWallet API exposes 4 endpoints covering national average mortgage rates, top-rated credit card recommendations, per-card detail pages, and mortgage editorial content. The get_mortgage_rates endpoint returns rate data across products like 30-year fixed and ARM loans, while get_credit_card_detail delivers pros, cons, ongoing APR, annual fee, and NerdWallet's own rating for any card review slug you supply.
Mortgage Rate Data
get_mortgage_rates returns two key objects: national_averages — an array of objects each containing product, interest_rate, and apr — and lender_offers, which may be populated when location context is provided. Optional parameters include zip_code, credit_score, down_payment, and purchase_price. These inputs may or may not shift the national average figures, but they provide borrower-profile context when lender-level results are available.
Credit Card Endpoints
get_best_credit_cards returns an array of card objects with id, name, description, url, and rating fields, reflecting NerdWallet's editorially curated top-card list. For deeper detail on any individual card, get_credit_card_detail accepts a card_slug matching the URL path used on NerdWallet review pages (e.g. chase-freedom-unlimited). The response includes pros, cons, ongoing_apr, annual_fee, rating, and the canonical url. If the slug does not correspond to a valid review page, the endpoint returns an input_not_found indicator rather than an error.
Mortgage Articles
get_mortgage_articles returns an array of objects with title and url fields drawn from NerdWallet's mortgage editorial section, including guides, calculators, and explainers. This endpoint takes no input parameters and reflects the current state of that section's content listing.

Does NerdWallet have an official public developer API?+
What does `get_credit_card_detail` return, and what happens if I use a wrong slug?+
name, url, rating, annual_fee, ongoing_apr, pros (array of strings), and cons (array of strings) for the matched card review. If the card_slug you supply does not match a valid NerdWallet review page, the response contains an input_not_found indicator rather than raising an HTTP error, so you should check for that field in your response handling.Does `get_mortgage_rates` return lender-specific offers, or only national averages?+
national_averages with per-product interest_rate and apr values. The lender_offers array may be populated when location and borrower parameters are provided, but it can also return empty. You should not rely on lender_offers being non-empty in all cases.Does the API cover personal loans, auto loans, banking products, or insurance from NerdWallet?+
Does `get_best_credit_cards` allow filtering by card category, such as travel or cash-back rewards?+
description and name fields often indicate reward type, so category filtering would need to be applied client-side. You can fork the API on Parse and revise it to add a category-specific endpoint if you need server-side filtering.
