switch from the-odds-api

Stop paying for credits.
Pay for requests.

Same drop-in response format. No per-market credit math. 100× the free-tier headroom (1,000 req/day vs 500/month). And on Streaming, you get 1,000,000 requests/day for $79 — their 15M-credit tier costs $249 and the "requests" math is 10–100× lower than the "credits" number suggests.

Enter your usage. We'll compute what each platform would cost. Math assumes ~3 credits per market on the-odds-api (their published range is 1–10).

That's 43K requests / day (1.3M / month) on PropLine, or 31M credits / month on the-odds-api.

Migrating: change one URL

We mirror the-odds-api's bookmakers[].markets[].outcomes[] shape, so most code paths keep working with two changes: the base URL and (optionally) 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"

Each request burns 1 credit per market × per region × per book combination. A single MLB call with 3 markets and a US region can cost 5–15 credits depending on response size.

After (PropLine)

curl "https://api.prop-line.com/v1\
/sports/baseball_mlb/odds\
?markets=h2h,spreads,totals\
&apiKey=$KEY"

One request = one debit. Markets are a free filter, not a credit multiplier. The same call returns 13 books + PrizePicks DFS in the response.

Path prefix is /v1 instead of /v4. Sport keys ( baseball_mlb, basketball_nba, soccer_epl) are identical. Auth supports ?apiKey= or X-API-Keyheader. Run your existing test suite against the new base URL — anything that touched bookmakers[], markets[], and outcomes[] should pass without edits.

Three features the-odds-api literally doesn't offer

Pricing is the obvious win, but the real moat is what you can't get over there at any tier.

01 · Resolution

Did the prop hit?

Every prop is graded against the actual box-score stat after the game. Each outcome carries resolution: "won" and actual_value: 6.0. Pro tier only. Their API stops at pre-game odds.

02 · Cross-book +EV

No-vig fair lines per book

The /evendpoint anchors on Pinnacle's sharp line, removes vig, and returns EV% per book at the same line. Build a +EV scanner in hours, not weeks.

03 · Webhooks

Push, not pull

Streaming tier ($79/mo) sends HMAC-signed line-movement and resolution webhooks with retry/backoff. Filter by sport, event, market, player. They're pull-only.

Where the-odds-api still wins

We'd be lying if we said PropLine wins on every dimension. If any of these matter to you, the-odds-api is probably the right call:

  • 60+ books across regions. We're at 13 books + PrizePicks DFS. UK / EU / AU books and Betfair Exchange are theirs (we cover Matchbook, Smarkets, Kalshi, and Polymarket on the exchange side).
  • 70+ sports. We focus on the 32 sports where prop resolution makes sense. They cover AFL, cricket, darts, snooker, etc.
  • Six years of historical depth. We launched in 2026 and have ~6 months. They have years — though our gap closes daily.
