Xbox Live Services API
Microsoft's Xbox Live Services REST API providing access to Xbox player profiles, gamertags, achievements, friends lists, game history, leaderboards, presence data, and social features for Xbox and Xbox Game Pass titles.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. OAuth 2.0 with Microsoft Identity Platform is robust. XSTS tokens are user-scoped, limiting blast radius. However, the multi-step token chain increases attack surface. No fine-grained API scopes beyond user-consent-based OAuth.
⚡ Reliability
Best When
Building companion apps, stat trackers, or social tools for Xbox and Game Pass players where Microsoft Account OAuth is feasible to implement.
Avoid When
You need server-side API access without user interaction, or are building outside the Microsoft ecosystem — the OAuth/XSTS token flow is heavyweight for simple integrations.
Use Cases
- • Retrieving Xbox player profiles and gamertag data
- • Fetching achievement unlock history and completion rates for games
- • Building social features using friends lists and presence data
- • Displaying game history and playtime statistics
- • Leaderboard queries for Xbox-enabled titles
Not For
- • Non-Xbox gaming platforms (PlayStation, Steam titles without Xbox Live integration)
- • Purchasing games or managing subscriptions (requires separate Commerce API)
- • Server-to-server automation without user consent (XSTS tokens are user-scoped)
- • Bulk data harvesting or competitive intelligence applications
Interface
Authentication
Requires Microsoft Identity Platform (Azure AD) OAuth 2.0 to obtain a Microsoft Account token, which must then be exchanged for an Xbox Live token (XBL3.0) via a two-step process, then optionally exchanged again for a title-specific XSTS token. This three-legged token exchange is significantly more complex than standard OAuth. XBL3.0 authorization header format is non-standard: 'XBL3.0 x={userhash};{XSTSToken}'.
Pricing
Access requires enrollment in the Microsoft Game Developer Program. Free for registered developers, but approval and onboarding take time. General public access to Xbox Live APIs is not available without developer enrollment.
Agent Metadata
Known Gotchas
- ⚠ Three-step token exchange (MSA -> XBL -> XSTS) must all succeed before any API call — token expiry at any stage requires full re-authentication
- ⚠ XSTS tokens are title-specific and user-scoped, meaning agents cannot make cross-user calls without separate auth flows for each user
- ⚠ The XBL3.0 Authorization header format is non-standard and easy to construct incorrectly
- ⚠ Many endpoints require the target user to have public or friends-visible privacy settings — private profiles return 403 with minimal explanation
- ⚠ Documentation is spread across Microsoft Learn, legacy MSDN docs, and GDK references with inconsistent content and versioning
