OpenOddsAPI

The Odds API alternative

The Odds API alternative
built for AI agents

The incumbent. Broad coverage, no agent tooling, no freshness signal.

Start free — 1,000 requests Read the docs

Switch in minutes, not hours

Three ways in, from least work to most control. Most people are done before the coffee is.

Fastest

Let your agent do it

Add the MCP server, then ask in plain language. Claude Code and Cursor discover every endpoint as a tool — you write no client code at all.

terminal
claude mcp add openoddsapi -e OPENODDSAPI_KEY=$KEY -- npx -y @openoddsapi/mcp-server
then paste this prompt
Migrate this project from The Odds API to OpenOddsAPI. Base URL becomes
https://api.openoddsapi.com/v1, the key moves from a query parameter to an
X-API-Key header, and responses now carry a per-bookmaker last_update and a
stale flag. Find every call site, update them, then make one real request and
print the result.
No code changes

Drop in the compatibility shim

Patch fetch once. Existing The Odds API-shaped calls keep working, served by us.

npm
npm install @openoddsapi/compat
Full control

Change two lines by hand

Swap the base URL and move the key into a header. The response shape is compatible, so parsing code is untouched.

- https://api.the-odds-api.com/v4
+ https://api.openoddsapi.com/v1

- ?apiKey=KEY
+ header: X-API-Key: KEY

Watch it happen

Your agent does the migration

One prompt. It connects to the MCP server, finds every call site, rewrites them, and proves the result with a live request — while you read this sentence.

Straight answer

Where The Odds API is the better choice

The Odds API covers 26 sports and around 50 bookmakers. We cover one sport. If you need a sport we do not carry yet, they are the correct choice and we are not.

Why teams switch

Your agent can call it directly

Point Claude Code or Cursor at our MCP server and it discovers every endpoint as a tool — no client code, no SDK, no docs archaeology.

You can see which books are stale

Every response carries last_update per bookmaker and a stale flag per source. A price shown as live when it is twenty minutes old is the worst failure mode in this category, and most APIs give you no way to detect it.

Exchanges and prediction markets sit beside the books

Kalshi and Polymarket prices next to FanDuel and Pinnacle, normalised to the same American odds.

Compare with others

OddsJamBuilt for bettors first. The API is an enterprise upsell behind a sales call. OpticOddsEnterprise aggregation at enterprise prices. Form-gated, six figures a year. OddsBlazeReal-time data costs $249/mo. Their $29 tier is delayed by about two minutes. SportsGameOddsObject-based billing that makes cost hard to predict.
