Free mortgage calculation API: no authentication, no key, no rate limit
and no signup. HTTPS and CORS confirmed against the live endpoint from a
third-party origin.
Endpoints cover monthly payment and amortization, affordability,
refinance break-even, closing costs, PMI and MIP, and property tax
reference data for all fifty states. The state data is also published
under CC BY 4.0.
Checked before opening: no mortgage or amortization API is currently
listed, the entry is alphabetical between Twelve Data and VAT
Validation, and the description is 76 characters.

Adds Worth the Rip — a free, no-key JSON API for sealed trading-card product
data: live TCGPlayer market prices, expected pull value, and profit margin for
460+ sealed products across 160 sets in 10 games (Pokémon, Magic, Yu-Gi-Oh!,
One Piece, Lorcana, and more), refreshed every 2 hours. Static JSON over a
CORS-enabled CDN — no auth, no rate-limit dance. Docs: https://worththerip.com/api/
Not a duplicate: TCGdex (already listed) serves singles card data; this serves
sealed-product prices and expected-value analytics, which no current entry covers.
