# MetaMarket

MetaMarket is cross-game software infrastructure that helps studios build lasting player relationships across their titles.

One backend runs your quests, progression, rewards, inventory, currencies, energy, and quotas as configuration rather than services you build. It carries one player identity into every title you ship.

**Build the first game. Reuse the foundation for every one after it.**

> Onboarding runs through the MetaMarket team. We register your app, prepare its configuration with you, and deliver the SDK. There is no self-service signup today. [Get in touch](https://metamarket.tech/#contact) to start.

## Get started

1. **Understand the model.** Read [One Player, Many Games](/core-concepts/one-player-many-games.md) to see what belongs to one game, what spans your portfolio, and who can change what. [Evaluate MetaMarket](/evaluate-and-integrate/evaluate.md) covers what to check before committing.
2. **Check what is available.** [Product Availability](/overview/current-scope.md) lists the status of every capability.
3. **Get access.** [Getting Access](/evaluate-and-integrate/getting-access.md) covers registration and what you receive.
4. **Make your first call.** The [Integration Walkthrough](/evaluate-and-integrate/quickstart.md) signs a player in, sends an action, and reads state back.
5. **Declare your mechanics.** [App Configuration](/evaluate-and-integrate/app-configuration.md) covers the configuration document your game runs on.
6. **Go live.** [Production Operations](/architecture-and-trust/production-operations.md) covers retries, idempotency, and error handling.
