ParlayAPI vs Goalserve

Name: ParlayAPI
Brand: ParlayAPI

Goalserve is a long-running sports-data provider that ships XML feeds priced per-product (livescores, fixtures, odds, h2h, lineups, etc.). ParlayAPI is a modern JSON-and-WebSocket sportsbook odds API on a single key. If you're maintaining an old Goalserve integration and the per-product cost has crept up, or you're starting fresh and don't want to parse XML in 2026, this is the migration path.

TL;DR. Goalserve has been around since 2008 and serves customers well at the schedule/fixture/lineup layer where their XML feeds are stable and predictable. For real-time betting odds, modern aggregator alternatives ship faster updates, richer market coverage, and easier integration. ParlayAPI is one of those alternatives.

Feature-by-feature

Feature	ParlayAPI	Goalserve
Wire format	JSON (REST + WebSocket)	XML feeds (per-product endpoints)
Product bundling	Single API key, all endpoints unlocked per tier	Per-product subscriptions (odds, livescores, h2h, etc. priced separately)
Sportsbook count	86+ books across 9 regions	30-50 books typical, varies by feed plan
Update cadence	Sub-second via WebSocket; 1-3s REST cache	30-90s typical poll cadence on odds feed
Cross-book arbitrage	Native /v1/sports/{sport}/arbitrage endpoint	Not offered; customer builds it from comparison feed
Devigged +EV scan	Native /v1/sports/{sport}/ev	Not offered
SGP correlation pricing	/v1/sgp/price with literature coefficients	Not offered
Historical closing lines	/v1/historical/closing-lines.csv free for signed-in users	Historical add-on, separate per-product fee
Reference clients	8 languages, single-file, stdlib-only or minimal deps	XML parsing left to customer
AI agent / MCP integration	Out-of-box MCP server (Cursor / Claude Desktop / Claude Code)	None
Pricing entry	$0 free tier (1,000 req/mo), starter $39/mo	Trial then per-product subscriptions; bundling adds up
Free try endpoints	No auth, no signup required	Trial requires email signup
Fixture / schedule data	Yes, /v1/sports/{sport}/events	Long-running stable feeds, this is core product
Live scores depth	Standard scores feed	Stronger; per-sport stat depth

When Goalserve is the right call

You're already integrated and the XML feeds are stable for your use case. Migration cost outweighs the integration improvement.
You need fixture / schedule / lineup data as the primary product, not odds.
You want per-product à-la-carte pricing rather than a bundled tiered subscription.
Your stack already has XML parsing well-handled.

When ParlayAPI is the right call

You're building a betting-focused product (arb scanner, +EV finder, betting agent, model-runner) where odds quality is the headline metric.
You're starting fresh and want JSON-native integration with reference clients in your language already provided.
You need sub-second freshness for arb / +EV detection. See our latency budget post for what that requires end-to-end.
You want cross-book analytics (arb, +EV, middles) shipped as endpoints rather than something you build yourself on top of the price feed.
You want AI-agent-ready integration via MCP servers for Cursor, Claude Desktop, and Claude Code.

Migration snippet

# Before (Goalserve XML)
GET https://www.goalserve.com/getfeed/{key}/getodds/soccer?bm=DRAFTKINGS,FANDUEL
# Returns XML; customer parses

# After (ParlayAPI JSON)
GET https://parlay-api.com/v1/sports/soccer_epl/odds
?regions=us&markets=h2h,spreads,totals&bookmakers=draftkings,fanduel
-H "X-API-Key: pak_live_..."
# Returns clean JSON; reference client handles parsing

Free key takes 30 seconds at /signup. The /v1/try/soccer_epl/odds endpoint works no-auth so you can verify the response shape before signing up.

What we don't claim

Goalserve has 17+ years of fixture / schedule / lineup data and per-sport depth that we don't aim to match. If schedules and lineups are your primary product and odds is supplementary, Goalserve is genuinely the better fit. We're focused on real-time betting markets; that's the lens for every feature trade-off we make. See our 12-point evaluation rubric for how to think about which provider matches which use case.
