TL;DR — what you get switching
Cheaper
$9 vs $30 / mo
Hobby starts at $9/mo with the full analytical feature set and no per-market credit cost; Pro at $19/mo adds 25,000 requests/day plus bulk CSV export. the-odds-api's starter is $30/mo for 100,000 credits, where each market call burns 1–10 credits.
Drop-in compatible
Same response shape
We mirror the bookmakers[].markets[].outcomes[] shape, so swapping api.the-odds-api.com for api.prop-line.com is the bulk of the migration.
Three features they lack
Resolution, history, +EV
Graded won/lost/push outcomes, full snapshot history for line movement, and Pinnacle-anchored no-vig +EV per book. The-odds-api offers none of these.
Side-by-side comparison
Honest tradeoffs — we win on price and graded data, they win on book count and sport breadth. Match your use case, not the brand.

When PropLine is the right call
- You're building a prop-betting product. 60+ player prop markets across MLB, NBA, NHL, soccer, UFC, plus alt lines (3+ / 5+ / 6+ strikeouts, alt spreads, team totals) all in one response. The-odds-api's prop coverage is thinner and costs 5–10 credits per request.
- You need to know if a prop hit. Our resolver polls official MLB / NBA / NHL / ESPN APIs after games and grades every Over/Under against the actual box-score stat. You get
resolution: "won"andactual_value: 6.0per outcome. The-odds-api gives you the odds but never the settled result. - You're modelling EV or building a +EV scanner. The
/evendpoint derives a no-vig fair line from a sharp anchor (Pinnacle preferred, Bovada fallback) and returns EV% per book, sorted with +EV plays at the top. Build a scanner in a few hours instead of weeks. - You want push delivery, not polling. Streaming Lite ($39/mo) and up sends HMAC-signed webhooks for line movement and resolution events with retry/backoff. The-odds-api is pull-only.
- Predictable per-request pricing. We charge per request, not per market-credit. A single MLB event odds call returns 50+ markets across all books for one request; the same call on the-odds-api can burn dozens of credits.
When the-odds-api is the better fit
We'd be lying if we said PropLine wins on every dimension. They're a mature product with real strengths.
- You need 60+ sportsbooks across regions. We're currently at 16 books, including 5exchanges (Matchbook, Smarkets, Novig, Kalshi, Polymarket). If your app needs deep UK / EU coverage or Betfair Exchange specifically, the-odds-api has those and we don't. AU is covered via TAB.
- You need 70+ sports. We focus on the 38 sports where prop resolution makes sense (MLB, NBA, NHL, NFL, NCAA, 27 soccer leagues, UFC, boxing, golf, tennis). They cover AFL, cricket, darts, snooker, etc.
- Six years of historical depth. We launched in early April 2026 and have ~2 months of history. They have years. If you're backtesting models against multi-season data, they're ahead today — though our gap closes every day.
- You're not in the US, or your end users aren't. Our books are licensed in US markets (plus TAB AU). If you need odds for a UK or EU audience, our Bovada/DK/FD/Pinnacle data isn't the right fit.
Migrating in under an hour
Because we mirror the the-odds-api response shape, most code paths keep working with two changes: the base URL and the auth header.
Before (the-odds-api)
curl "https://api.the-odds-api.com/v4/sports/baseball_mlb/odds?markets=h2h,spreads,totals&apiKey=$KEY"After (PropLine)
curl "https://api.prop-line.com/v1/sports/baseball_mlb/odds?markets=h2h,spreads,totals&apiKey=$KEY"Path prefix is /v1 instead of /v4; sport keys (baseball_mlb, basketball_nba, etc.) are identical. Auth supports ?apiKey= or X-API-Keyheader, same as theirs. Run your existing test suite against the new base URL — everything that touched bookmakers[], markets[], and outcomes[] should pass without edits.
