Lender League Table / Market-Share Report
See where every lender ranks. For a state and mortgage product, RateAPI returns the ranked roster of the top N lenders publishing today — each lender's best APR/rate, its league position, and how many basis points it sits above the leader — plus the market min, median, and max. This page explains how it works and what the API returns. Run it in the dashboard, or call the API / MCP directly. Powered by real, ranked credit union rates — not affiliate revenue.
RateAPI returns a lender league table — a ranked roster of the top N lenders publishing a given mortgage product in a state today, with per-lender best APR/rate, league position, and basis points above the leader, plus the market min/median/max. It extends the benchmark (which returns only min/median/max and the single lowest institution) with the full ranked table.

A lender league table is a ranked roster of the top N lenders publishing a mortgage product in a state today, ordered by their best APR. Each row shows the lender name, its best APR/rate, its league position, and how many basis points it sits above the market leader. It is the client-facing competitive-landscape view — the full ranked table behind the market min, median, and max benchmark.
What a League Table Returns
A league table is a ranked roster of lenders for one state and product. Each row is a single lender's best published offer, ordered ascending by the chosen metric:
- Rank / position — 1 is the market leader; positions ascend by best APR (or rate).
- Lender name — the credit union publishing the offer.
- Best APR / rate — that lender's lowest live APR and rate for the product.
- Product — the mortgage product the row applies to (30yr_fixed or 15yr_fixed).
- Basis points above the leader — how far each lender sits above position 1.
Alongside the table you get the market min, median, and max APR and the total lender count — so the league table extends the single-number benchmark with the full ranked roster. Lenders also weigh credit score, equity, and loan size; published rates are a starting point. Verified June 11, 2026.
How It Works
From State and Product to a Ranked Roster
One call returns the ordered table plus the market block
Pull the League Table for a State and Product
POST a state, a product, and an optional limit to the league-table endpoint. RateAPI ranks every lender publishing that product in the state by best APR (or rate) and returns the top N rows, each with its position and basis points above the leader, plus the market min/median/max. The same logic ships as the MCP tool get_league_table and the in-app report at /league-table in the consumer app.

Frequently Asked Questions
Quick answers about the lender league table
A lender league table is a ranked roster of the top N lenders publishing a given mortgage product in a state today, ordered by their best APR (or rate). Each row shows the lender name, its best APR/rate, its league position, and how many basis points it sits above the market leader. It is the client-facing competitive-landscape view of a state and product market.
A benchmark returns only the market min, median, and max plus the single lowest institution. A league table extends that with the full ranked table — every one of the top N lenders, in order, with each lender's best APR, its position, and its basis points above the leader. You still get the market min/median/max, but now with the roster behind it.
Three things: a 2-letter US state code, a mortgage product (30yr_fixed or 15yr_fixed), and an optional limit for how many lenders to return (default 10, clamped to 1–50). You can also choose to rank by apr (default) or by rate.
A ranked table of lenders (position, name, best APR, best rate, product, and basis points above the leader), the count of rows returned, the total number of lenders in that state and product market, a market block with min/median/max APR, and a human-readable note summarizing the leader and market size.
The league table is built from the same ranked credit union rate path that powers the benchmarks — real published rates from 4,300+ US lenders across 50 states. There is no affiliate weighting; lenders are ordered purely by their best APR or rate.
