OddsBlaze is a fast, well-built odds API aimed at serious sharp bettors and sportsbook operators, priced accordingly - its published entry plan starts at $299/month with no free tier. ParlayAPI covers more sources overall, ships a genuinely free tier, and links pricing straight to our live page instead of a fixed number that goes stale. OddsBlaze, in turn, ships a millisecond-accurate historical odds-replay endpoint and a metered same-game-parlay pricing tool that we don't have as a first-class feature - see the honest section below.
ParlayAPI numbers are from our internal verified-numbers ledger, measured live against production, as of 2026-08. OddsBlaze numbers are pulled directly from their own public pricing and docs pages, sourced inline below - read 2026-08-09. Pricing drifts; always check /pricing and OddsBlaze's own pricing page before you budget.

The rule for this page: if we only flatter ourselves, it's a sales page, not a comparison. Here's where OddsBlaze is genuinely the better tool.
Pricing drifts on both sides. ParlayAPI's numbers below link to our live pricing page rather than a hardcoded figure. OddsBlaze's numbers are what their public pricing page showed on 2026-08-09 - verify both before you commit a budget.
OddsBlaze and ParlayAPI use different request shapes, so this isn't a one-line swap the way our the-odds-api page is. What it looks like to bring an OddsBlaze integration over:
# OddsBlaze: key + sportsbook + league as query params
curl "https://odds.oddsblaze.com/?key=your_key&sportsbook=draftkings&league=nfl"
# ParlayAPI: sport key in the path, apiKey as a query param curl "https://parlay-api.com/v4/sports/americanfootball_nfl/odds?regions=us&markets=h2h&apiKey=YOUR_PARLAY_KEY"
pip install parlay-api from parlay_api import ParlayAPI client = ParlayAPI(api_key="YOUR_KEY") events = client.odds("americanfootball_nfl", regions="us", markets="h2h,spreads,totals") # Plus our extensions props = client.props("baseball_mlb", markets=["player_strikeouts"]) fair_o, fair_u = ParlayAPI.devig(over_price=-110, under_price=-110)
