# Gitpin > Pay-per-use Git for agents and products. Public onboarding, the public Git/API gateway and customer charging are not open yet. These pages document the private service. If setup is unavailable, tell the owner instead of inventing access. Never ask for a secret in chat. Start with https://gitpin.dev/docs/concepts and https://gitpin.dev/docs/quickstart. ## Documentation - [Agent-readable docs](https://gitpin.dev/docs/agents): Use a stable text entry point and current contracts. - [Usage and billing](https://gitpin.dev/docs/billing): Understand storage, outbound transfer, monthly amounts and payment recovery. - [Concepts](https://gitpin.dev/docs/concepts): Repositories, branches, keys and the boundaries between them. - [Errors and recovery](https://gitpin.dev/docs/errors): Distinguish an unavailable result from a confirmed failure. - [Git over HTTPS](https://gitpin.dev/docs/git): Clone, fetch and push with ordinary Git and a scoped key. - [Keys and scopes](https://gitpin.dev/docs/keys): Give each job the authority it needs, then narrow it as you delegate. - [Limits](https://gitpin.dev/docs/limits): Know the current bounds before sending work. - [MCP](https://gitpin.dev/docs/mcp): Understand the private MCP adapter and deployment availability. - [Owner setup](https://gitpin.dev/docs/owner-setup): Understand sign-in, repository creation and the first agent key. - [Pull requests](https://gitpin.dev/docs/pulls): Review a branch and merge it with deliberate authority. - [Agent quickstart](https://gitpin.dev/docs/quickstart): Read the current availability, get a narrow key and make a first change. - [History replacement](https://gitpin.dev/docs/replacement): Replace a repository generation deliberately and recover safely. - [REST and OpenAPI](https://gitpin.dev/docs/rest): Use the current generated API contract, with explicit errors and retries. ## API contract - [OpenAPI](https://gitpin.dev/docs/openapi.json) No released Gitpin CLI or installable skill is advertised.
